Factionalism in the medieval Low Countries

Factionalism in the medieval Low Countries, in Dutch historiography known as partijstrijd or (partij)twisten, comprises several political, military and socio-economic conflicts in the Low Countries during the Middle Ages, especially the Late Middle Ages (circa 1300 to 1500). The so-called 'parties' (Dutch: partijen) usually behaved like factions, which were formed ad hoc, could rapidly change in composition, and usually did not have strong ideological underpinnings.
