Pressing and urgent domestic problems were the justification for L. Cornelius Sulla's election to the dictatorship in 82 b.c.Footnote 1 He responded with an extensive legislative programme which reorganized the judicial and legislative processes of the res publica.Footnote 2 While there is agreement, in broad terms, about the nature of these changes, their purpose and significance remain debated.Footnote 3 None the less, there is general consensus that the Senate's role in Sulla's res publica was enhanced in comparison with earlier periods.Footnote 4 This conclusion is based on the increase in the size of the Senate; on the monopoly it resumed of judicial decision-making in the iudicia publica; and on the extension, in practice, of its legislative capacity, given that its decrees could not be vetoed by tribunes of the plebs, who had also lost their capacity to put forward legislation. Flower offers a recent and concise summary: ‘This new “consensus” of Sulla was based on force and on the necessity of agreeing with Sulla himself, and subsequently with his new, mighty senate that was expected to wield unprecedented power and absolute authority.’Footnote 5
Two hypotheses are required to support this view of Sulla's Senate: first, that his proposals were designed to enhance the role of the Senate, or even, in a stronger version, to ensure that it monopolized political power; and secondly, that they were implemented in such a way that, in practice, the Senate acquired greater power and authority than it had had previously. The purpose of this article is to scrutinize these claims: it will suggest that neither can be accepted without modification. Sulla's package of constitutional change combined solutions to specific problems with an attempt to eliminate conflict from the res publica, and the resulting mix of measures was incoherent. The Senate's position was different as a result of Sulla's changes, but not necessarily stronger. In addition, their implementation was affected both by the nature of his dictatorship and by the recent history of the Senate. These factors created a Senate which was structurally weak, divided, and ineffectual.
A determination to remove opportunities for destructive conflict from the structure of the res publica is a convincing framework within which to understand the changes Sulla introduced to the role of the tribunate of the plebs and to the composition of juries, both of which had effects on the role and composition of the Senate. Every episode of domestic violence over the previous half-century had had its origins in a dispute over legislation proposed by a tribune.Footnote 6 Sulla's own consulship in 88 had come under unprecedented attack from the tribune Sulpicius, and he had narrowly escaped death in the rioting which occurred as a result of Sulpicius’ proposals and which had led to the death of his daughter's husband.Footnote 7 The kind of arguments which could be put forward to legitimize the restriction of the tribunate to prouocatio on behalf of individual citizens are also evident: that that was the initial function of the tribunate and that the legislative activity by individual tribunes was supported by an unrepresentative faction with the citizen body.Footnote 8 However far the ban on tribunician legislation seemed to subsequent commentators to be an unworkable and unstable attempt to silence the urban populace, we need not posit an unsustainable level of self-delusion on Sulla's part in the belief that restricting legislation to citizens voting in the comitia centuriata on proposals put forward by consuls and praetors might solve, or at least substantially mitigate, the problem of violent factionalism.Footnote 9 This reorganization of legislative practice gave a much greater role to imperium-holding magistrates than hitherto; it also affected the Senate, whose decrees no longer faced the threat of veto.
The change in the composition of the juries can also plausibly be linked to eliminating dissension between equestrians and senators and the exploitation of that conflict by others. That dispute had been an important, if indirect, factor in the outbreak of the Social War in 91, a catastrophe from which all other more recent disasters could be seen to flow. Once Sulla had decided to rebuild the iudicia publica around seven new standing courts and to provide their juries from the Senate, it would have been apparent that many more senators would be required simply in order to provide an adequate number of jurors.Footnote 10 The rise in the number of praetors from six to eight ensured that each court had a praetorian president; and a future supply of an adequate number of jurors was ensured by the extraordinary growth in the number of quaestors to twenty.Footnote 11
Sulla introduced a variety of changes to the Senate. Senatorial membership had been the responsibility of the censors, but the senatorial lectio was now replaced, as the means of entering the Senate, by the elections for the quaestorship, since quaestors now participated in the Senate from their election, even if they were not formally members until enrolled by the censors.Footnote 12 The role of princeps senatus appears to have fallen into abeyance, and the princeps’ privileged speaking position during debate to have fallen to one of the consulars, whose identity changed from year to year.Footnote 13 The consular who would speak first that year was identified at the start of the year by the consul who presided during January, and was expected to agree with that consul.Footnote 14 The presence of all eight praetors in Rome during their year in office, the tendency for the consuls also to be present throughout the year, and the much earlier elections contributed to a major change in the nature of senatorial debate, in which magistrates now played a much more dominant role.Footnote 15 The post-Sullan Senate was run by the consuls, with a significant role in the second half of the year for the consuls-elect.Footnote 16 Even had other factors not conspired against the authority of senior priuati in the Senate, that is the principes, this shift towards the presence of imperium-holders in Rome alone undermined their position.
A range of other factors also weakened the principes. The Senate which Sulla found after his victory in 82 had been hollowed out by the violence of previous years; the proscriptions he presided over compounded the effect. As few as half those enrolled by the censors in 86 might now still be alive and able to attend.Footnote 17 One particularly striking aspect of these losses was the very small number of ex-consuls and ex-praetors present.Footnote 18 When Sulla assumed the dictatorship in 82, he was still the most junior surviving consular present in Rome, despite having held the office in 88: everyone who had held that office with him or subsequent to him was dead, about to die, or in exile.Footnote 19 This is an extraordinary rate of attrition, unparalleled in any other period of Republican history.Footnote 20 Moreover, these losses were in addition to consular deaths during the Social War, and the deaths of earlier holders of the office during the civil conflicts of 88–87 and of 82.Footnote 21
In consequence, only four consulars, apart from Sulla, are known to have been alive and able to participate in the Senate in 82: L. Valerius Flaccus (cos. 100), C. Valerius Flaccus (cos. 93), M. Perperna (cos. 92), and L. Marcius Philippus (cos. 91).Footnote 22 L. Flaccus led the senatorial negotiations with Sulla after the latter's arrival in Italy, and as interrex after Sulla's victory he ensured some semblance of propriety to the installation of Sulla as dictator; he was, moroever, Sulla's Master of Horse.Footnote 23 His cousin C. Flaccus appears to have missed all the domestic excitements of the previous decade, through an extraordinarily extended proconsular command in Spain and Gaul: he returned to Rome, and a triumph, only in 81 b.c. These men – both, like Sulla himself, patricians – played an important part initially in legitimizing Sulla's activity, but neither seems to have had a prominent role after 81. M. Perperna was, as far as is known, almost entirely inactive, and this may be connected with his son's opposition to Sulla; but he was still alive.Footnote 24 The only pre-82 consular who is attested as an active member of the post-Sullan Senate was L. Marcius Philippus.
Information for men of praetorian standing is less complete, but indicates a similar pattern.Footnote 25 Eight ex-praetors can firmly be placed in the Senate in 81.Footnote 26 This category produced five of the six consuls of 81–79 (with Sulla himself being the sixth), evidence that Sulla placed considerable importance on re-establishing a pattern of regular office-holding in accordance with the lex annalis.Footnote 27
Sulla's Senate thus had an unprecedently tenuous connection in terms of membership with the body that had existed ten years’ earlier at the outbreak of the Social War. Pre-Social War senators who survived into the Sullan period were also subject to brutal demonstrations of the nature of Sulla's power. These began even before the proscriptions. Plutarch (Vit. Sull. 30.2–3) records a Senate meeting which Sulla summoned soon after his victory at the Colline Gate:
ἐκάλει τὴν σύγκλητον εἰς τὸ τῆς Ἐνυοῦς ἱερόν. ἅμα δ’ αὐτός τε λέγειν ἐνήρχετο καὶ κατέκοπτον οἱ τεταγμένοι τοὺς ἑξακισχιλίους. κραυγῆς δέ, ὡς εἰκός, ἐν χωρίῳ μικρῷ τοσούτων σϕαττομένων ϕερομένης καὶ τῶν συγκλητικῶν ἐκπλαγέντων, ὥσπερ ἐτύγχανε λέγων ἀτρέπτῳ καὶ καθεστηκότι τῷ προσώπῳ προσέχειν ἐκέλευσεν αὐτοὺς τῷ λόγῳ, τὰ δ’ ἔξω γινόμενα μὴ πολυπραγμονεῖν· νουθετεῖσθαι γὰρ αὐτοῦ κελεύσαντος ἐνίους τῶν πονηρῶν.
He summoned the Senate to meet in the Temple of Bellona. Just as he began to speak, by arrangement his men began to execute the six thousand [sc. prisoners]. The noise of so many men being slaughtered in a small area was audible and the senators were terrified; but Sulla continued to speak with an unchanged and immoveable expression and instructed them to pay attention to what he was saying and not to worry about what was taking place outside; some wrong-doers were receiving correction, on his orders.Footnote 28
The Temple of Bellona was outside the pomerium, and not infrequently used as a meeting place for the Senate when the attendance of an imperium-holder was required; on this occasion, it had the added advantage of proximity to the Villa Publica and Circus Maximus, where prisoners of war captured after the Battle of the Colline Gate were being held.Footnote 29 It had only been a matter of weeks since that year's urban praetor, M. Iunius Brutus Damasippus, had ordered a massacre at a meeting of the Senate which he had convened; now Sulla was demonstrating what would happen to his enemies.Footnote 30 This initial act of terror was followed over the next six months by the organized terror of the proscriptions. In a gruesome indication of the lawlessness which followed Sulla's victory, the idea of a written list – the defining feature of the proscriptions, on this occasion and subsequently, and the source of the name – was itself presented as a concession, in so far as it set limits to what was otherwise the indiscriminate elimination, by Sulla's followers, of their personal enemies.Footnote 31
The device of proscription turned Sulla's purge of his and his followers’ enemies into a bureaucratically supported redefinition of a selected group of citizens. The property of the proscribed became the state's; they themselves lost the state's promise of protection in case of violence; and the citizen rights of their male descendants, for two generations, were curtailed.Footnote 32 The neatness of the process was underscored by its having a fixed endpoint of 1 June 81, enshrined in the law which authorized the proscriptions.Footnote 33 Glimpses of the consequences in communities outside Rome can be caught in some of Cicero's early speeches, particularly his defences of Sextus Roscius of Ameria and Cluentius: those members of local elites who were acknowledged supporters of Sulla were able to extend their political and economic power substantially. Conversely, Sulla attempted to revoke the citizen status of some of the communities which had opposed him.Footnote 34 Other Italian towns were now neighbours to settlements of Sullan veterans established on confiscated land.Footnote 35
The elimination of Sulla's enemies through the proscriptions was accompanied by continuing news of their defeat overseas and the public demonstration of these successes in Rome. Gnaeus Pompeius had pursued the consul Carbo, captured him in Sicily, and had him executed; Pompeius then crossed to Africa and captured and killed Cn. Domitius, one of the proscribed, who had raised an army and gained the support of the local ruler Iarbas. Only in Spain did Roman opponents of the new regime maintain a presence beyond the end of 81. On 28 January 81 Sulla held a triumph over Mithridates, remarkable not only for the display of booty but also – according to Plutarch's account – for the presence in the procession of Sulla's elite supporters declaring that they were returning from exile.Footnote 36 Sulla concluded his triumph with a contio at which he gave an account of his res gestae and took the title ‘Felix’.Footnote 37 Also during 81, Murena held a triumph over Mithridates and C. Valerius Flaccus from his campaigns in Spain and Gaul. Within a single year, three Sullan commanders had demonstrated the new regime's military capacity.Footnote 38 At Rome, Sulla's unique status was made visible during his dictatorship in the 24 lictors who accompanied him. He altered religious practice through the addition to the annual cycle of festivals of ludi victoriae, which commemorated the battle at the Colline Gate and were first held in 81; and, probably also in this year, he redrew the city's boundaries by extending the pomoerium for the first time since the regal period.Footnote 39 Rome was now, temporally and spatially, a Sullan city.
The Senate, too, became Sullan. Few if any surviving senators can have been known opponents of Sulla, and many had welcomed his return with enthusiasm; Sulla's relentless assertion of his power must surely have deterred any waverers from expressing even modest hesitation about the changes which were taking place. In addition, surviving senators were soon joined by a large number of new senators, in whose appointment support for Sulla was the major criterion. The act of appointment itself recalled the quinquennial censorial lectio, though there were important differences in the lectio of 82 or 81: Sulla did not hold the office of censor, he appointed a much larger number of new senators than the censors tended to, and many of his appointees did not meet the usual criteria for senatorial membership.Footnote 40
Appian gives the number of appointees as ‘around three hundred’ (B Civ. 1.100) and these appear to have been drawn from two distinct categories.Footnote 41 One was those men who would have expected to be enrolled in the Senate at the next lectio, because they had held a qualifying office since the census in 86. It seems that Sulla did include this category (excluding, of course, those of its members who had fought against him in the civil war which preceded his dictatorship), together with that of those who had held the quaestorship since 86.Footnote 42 To this extent, his lectio followed traditional practice. But former office-holders, even including ex-quaestors, could have provided only a fraction of the number which Sulla had decided to recruit, particularly given that some in this category had been killed during the fighting and others were ineligible because they were Sulla's enemies.Footnote 43 Consequently, we can reasonably infer – although no individual in this category can be identified with complete confidence – that the remaining Sullan appointees had not held elected office at Rome.
The epitome of Livy says that Sulla filled the Senate ex equestri ordine (Per. 89); technically, new senators were always former equestrians, but this passage may imply that some at least came from non-senatorial families.Footnote 44 In this connection, there is a considerable number (43) of individuals who are attested in the Senate after 80 but are not known to have held a magistracy.Footnote 45 This group of new senators who had not held elected office were, we can reasonably assume, fervent supporters of Sulla, and very probably beneficiaries of the proscriptions: the process of appointment was an opportunity for Sulla to reward his adherents from the equestrian class with senatorial status. But it is impossible to reach any very satisfactory conclusions about the identity of the new senators beyond the characteristics of Sullan and equestrian, and the most recent prosopographical survey describes its results as ‘disappointing’.Footnote 46
This lectio made the Senate larger than it had ever been, with about 450 members, some two-thirds of whom were new. Thereafter, there was a change from appointment through a lectio to membership following automatically from election to the quaestorship. Since the number of quaestors had risen to 20, the Senate's larger size would be maintained through the accession of 20 new senators each year.Footnote 47 The actual size of the Senate after Sulla as a result of the increase in the number of quaestors to 20 cannot be calculated in the absence of actuarial tables and membership data; in addition, the Sullan system did not quite have time to settle into a stable state.Footnote 48 For an annual recruitment of 20 individuals aged 30 to produce an overall size of 600, an average male life expectancy, at the age of 30, of 60 years is required. This figure is higher than most modern estimates of probable Roman population structure.Footnote 49 It also contrasts with the imperial Senate: this body also recruited 20 quaestors a year and maintained a size of 600, but the minimum age for entry was 25. A reasonable conclusion is that the size of the post-Sullan Senate rose gradually from a total of around 450, immediately after Sulla's co-options, towards a figure between 500 and 600.Footnote 50 The size of the new Senate was soon noticeable in built form, since Sulla enlarged the existing Senate House.Footnote 51
The Senate as Sulla recreated it was not the body it had been prior to the Social War. That Senate had been composed of the res publica’s greatest men, chosen by the censors, whose decisions mediated the popular will, as demonstrated in elections for higher office, through their judgement of individual virtue. Sulla's Senate contained his adherents, men identified for their personal loyalty during civil war. The composition of his Senate, combined with the exclusion of his enemies’ descendants from public office, ensured that the consequences of civil war would continue to be embedded in the res publica for decades.Footnote 52 Decisions about its membership thereafter were handed directly to the people, whose capacity to choose was none the less limited, in so far as senatorial membership now depended on the relatively undiscriminating quaestorial elections.Footnote 53
The effects of this strongly Sullan membership were compounded by the increase in size. Hawthorn neatly summarized the issue: ‘There is almost nothing you can do to an exclusive and aristocratic body which is worse than flooding it with new members’.Footnote 54 The survivors of the pre-Sullan Senate found themselves outnumbered, perhaps by as much as two to one, by new members whose qualifications for being chosen included their loyalty and commitment to Sulla and his regime and whose prior experience of participation in the res publica was in many cases limited or even non-existent.Footnote 55 The experience of the new senators as senators was also very different. Sulla's nominees to the Senate were not all, as we have seen, former office-holders; and there does not seem to have been any obligation on them to stand for the quaestorship subsequent to their joining the Senate.Footnote 56
There was thus, from 81 onwards, a group of senators, initially around 250 in number and gradually declining thereafter as a result of natural wastage, who had never held an elected office. The role of this group was, in all probability, to serve on juries. That was a consequence of Sulla's decision to entrust the juries in his new courts to senators; and although we have little evidence for the way in which other senatorial tasks were allocated, it seems unlikely that they would have been handed over to men who had no prior experience of administering the res publica.Footnote 57 Ryan's hypothesis that it is this group of men who were called pedarii is very attractive.Footnote 58 The name suggests a degree of scorn from their office-holding senatorial peers. There was a tension between the reality of an enlarged Senate, divorced from its traditional relationship with the Roman people through office-holding, and the presentation of Sulla's victory as that of the nobilitas.Footnote 59 This tension may have contributed significantly to the extraordinary lectio conducted by the censors elected in 70 b.c., which expelled an unprecedented 64 senators; apart from one of the consuls of 71, Sura, no senator who had held imperium is attested among those expelled. If the censors of 70 were defining, however informally, unworthiness to belong to the Senate in terms that targeted the surviving Sullan appointees, then the general message of renewal and reform to which their lectio contributed would be supplemented by a specific move away from the Sullan Senate as constituted during the previous decade.Footnote 60
Sulla's appointments to the Senate increased its size very considerably and were, it appears, embedded informally in a distinction between those who had entered in this manner and those who had served as magistrates. The new senatorial class inevitably drew on a wider group of families than those who had filled the pre-Social War Senate; but the existing elite was not replaced, except in so far as individual families had chosen the wrong side in the civil war, and its pre-eminence was confirmed initially by Sulla's support in consular elections and subsequently, for whatever reason, by the electorate. Sulla's changes to the Senate were not driven by a wish for, and did not result in, a change in the composition of the ruling elite.
Their purpose and explanation lie elsewhere in his programme of change. Flower has more recently described Sulla's republic as ‘a political constitution based on laws and their regular enforcement by a system of courts’.Footnote 61 This interpretation offers an attractive framework for understanding what Sulla attempted to achieve, and can be connected with the changes to senatorial procedure which reduced scope for debate, as well as to the creation of a group of senators whose role, as jurors, was ‘the task of policing Roman society, and especially the behaviour of its most powerful senatorial elites’.Footnote 62 Moreover, it gains further support from a consideration of the Senate's behaviour in the recent past, when the Senate had taken a line of action distinct from that of the consuls, with destructive consequences.Footnote 63 The shift in power from the Senate to imperium-holding magistrates that resulted from Sulla's changes can be seen as a response to these moments of conflict which, as elsewhere in his programme, sought to establish unipolar rather than multipolar locations of power. These separate spheres were now defined by law.Footnote 64
Such a reading is radically different from the standard interpretation of Sulla's res publica as one in which the Senate was dominant. But even so it arguably does not quite go far enough in explaining either Sulla's purposes (in so far as those can be divined) or the results which actually occurred. The Senate became – and perhaps Sulla conceptualized this as a return to – a consilium for magistrates, whose function was to offer advice when asked for it by magistrates. As the body which contained the res publica’s most distinguished citizens, it was also the right organ from which to draw the jurors in legal cases which affected the res publica. If that were the case, it would explain why Sulla was willing to recruit so heavily into his Senate; it did not need the authority to act independently, and he had no cause to be concerned about the outraged feelings of its existing members.
Finally, this interpretation of the Sullan Senate helps to explain why, in practice, the Sullan res publica did not last, either in its initial form beyond 70 or more fundamentally beyond the outbreak of civil war in 49. Many other factors, above all the response of the Roman people to their loss of power and prestige, are involved. But the Senate was a major design flaw in the overall framework of the res publica as constituted by Sulla. It was composed of two groups with interchangeable membership and conflicting ambitions: those who policed the actions of the res publica’s agents through the courts, and those who acted for the res publica as magistrates.Footnote 65 Such a system of oversight could only work effectively if the two groups remained separate, but there was continual traffic between the two groups, as men stood for office, were elected as magistrates, and then returned to the status of private individuals. If Sulla had hoped that his appointees would act as a bulwark for his changes he was to be disappointed; and he was himself largely responsible for its failure, because he did not provide a mechanism for their renewal and because he also supported the re-emergence of an exclusive nobility which largely monopolized access to imperium. This group, in turn, had only a few years to wait before they felt confident in challenging Sulla's res publica, and its senatorial supporters, and restoring, albeit in an unstable form, a framework which permitted the traditional exchange of favours between aristocrats and the Roman people.
The view that Sulla strengthened the Senate can only be maintained if one believes that larger bodies are more effective than smaller ones. That is clearly not the case. At somewhere between 500 and 600 members, the post-Sullan Senate was not a place where productive discussion took place. It existed to confirm the distinction of those whom the Roman people had elected to office and to demonstrate that the res publica’s best citizens advised its magistrates on the conduct of public affairs. It had a useful subsidiary role of avoiding judicial conflict by supplying jurors. But its prominence after Sulla is an illusion, created by the suppression of the people. Sulla's vision had no need of a ‘strong Senate’: power and authority belonged to the magistrates.
