United in revolt and discourse: urban and noble perceptions of ‘bad government’ in fifteenth-century Brabant (1420–1)

This case study on the Brabantine uprising of 1420–1 reveals common ground between noble and urban political values, calling into question the dominant historiographical cleavage between noble and urban ideologies. In 1420, one of the most severe political conflicts in Brabantine history caused a coalition of members of the upper nobility and Leuven city councillors to remove Duke John IV from the throne and convict his councillors. Preceding these drastic events, both parties had written texts together to legitimise their political position and attract supporters. By analysing the writings of the insurgents, this article illustrates how these noblemen and urban councillors combined their political ideas in practice to create a coherent discourse that supported their claims to power. The analysis also emphasises the insurgents’ appropriation, interpretation and use of key notions, such as the ‘common good’, to criticise Duke John’s government and promote their cause.
