How did Holland’s wealth give Johan van Oldenbarnevelt influence in the United Provinces?

Johan van Oldenbarnevelt’s influence in the United Provinces was fundamentally rooted in his position as the landsadvocaat (chief minister) of Holland, which had become the preeminent province within the union. Following the reconquest of Brabant and Flanders by Spanish forces, Holland emerged as the dominant political and economic power, contributing nearly 59 percent of the federal budget.12

As Holland’s chief exponent and advocate, Oldenbarnevelt leveraged this financial weight to coordinate the republic's resources, effectively making the state's military efforts possible. Because the central government lacked direct taxation powers and relied on provincial contributions, Holland’s status as the primary financier granted Oldenbarnevelt significant leverage in shaping national policy and integrating the commonwealth of rebels. He utilized this position to act as the union's de facto foreign secretary, managing diplomatic missions and securing international alliances that solidified the independence of the northern provinces. Consequently, his authority was inextricably linked to the wealth of the province he represented, allowing him to serve as the primary counterweight to the political influence of the princes of Orange.1234
