In the early 1370s, when serfdom had all but disappeared in Flanders, Count Louis II resumed the collection of mortmain, a death fee usually paid only by those of servile status. In a region with a sophisticated financial system it is striking that rather than accepting payment in cash the Count's bailiffs secured personal items. In this paper it is argued that the Count was thereby taking advantage of a population dazed by the ravages of plague and by the on-going civil war between himself and a number of the towns within his territory. Traditional local bonds such as mortmain, extended and reinterpreted within a new constellation of power, enabled Flemish counts to turn a fee into a tax, highlighting their authority.
