The "Vierlander" groat takes its name from the monetary agreement of 1434 binding four Burgundian territories — Flanders, Brabant, Holland, and Hainaut — to a unified coinage standard, one of the more ambitious currency coordination efforts of the medieval Low Countries. Philip the Good pushed the arrangement as part of a broader effort to rationalize commerce across his expanding domains, though local mints retained enough independence that die workmanship varies considerably across the participating counties.
Hainaut examples struck under this agreement are modestly scarcer than their Flemish counterparts in surviving collections, reflecting the county's smaller mint output during the period.
