During the Geometric period (ca. 900–700 BCE), the sociopolitical structure of Big Men became collaborative aristocratic rule. Most Geometric buildings had fieldstone foundations, mudbrick walls, and pitched thatch roofs, or, in the Cyclades and Crete, fieldstone walls and flat roofs. Larger dwellings were usually apsidal or rectangular, smaller dwellings often oval. In the eighth century, a large household could include separate buildings and areas inside an enclosure (Oropos, Eretria). By 700, multi-room rectangular houses with a courtyard appear (Zagora). Sanctuaries in settlements were usually open-air. Sanctuaries outside settlements proliferated in Late Geometric as sites of elite display and competition; rituals included animal sacrifice, communal feasting, and votive offerings. Monumental temples were built 725–700 at Eretria, Amarynthos, Naxos, Samos, Kalapodi, and Ano Mazaraki, all extra-urban except Eretria. Geometric burials were generally inhumations, though cremation was common in Athens/Attica. On pottery, angular geometric motifs replaced Protogeometric circular designs. Figured scenes (funerals, battles) appear in the mid-eighth century and possibly mythological scenes in the late eighth century. Greeks, probably Euboeans, borrowed the Phoenician alphabet ca. 800 BCE; early inscriptions were scratched on pottery, some in poetic meter. By ca. 700, many settlements had developed into the politically organized community called a polis.

Thucydides served as elected general (strategos) for Athens, and it is likely that he had (perhaps extensive) personal experience of warfare. His work is therefore an important guide both to the practicalities of warfare in 5th-century BCE Greece and to the wider function(s) that war played in politics and society. This chapter analyses what the History tells us about the ‘art of war’ in this period, discussing the use of land troops (light-armed soldiers and cavalry as well as hoplites) and naval forces. It discusses military strategy and tactics, the nature of combat and the consequences of warfare, for non-combatants as well as soldiers.

This chapter studies the four branches of the Athenian armed forces. For each branch, it discusses the legal and social positions of branch members, the means by which they were recruited and called up, and the history and the organization of their branch.
