Overview

Concluded on 23 January 1579, the "closer union" of the northern (and some southern) provinces of the Low Countries — Holland, Zeeland, Utrecht, Guelders and others, later joined by cities such as Ghent, Antwerp, Bruges and Breda — formed to prosecute the revolt against Philip II more effectively (in counterpoint to the Catholic-royalist Union of Arras in the south). It confirmed the powers of the provincial stadtholders and provided for common defence while preserving provincial autonomy. It is regarded as the founding compact of the Dutch Republic and functioned, in effect, as its constitution for over two centuries.
