Why did Johan van Oldenbarnevelt seek a strong political position for Holland within the United Provinces?

Johan van Oldenbarnevelt sought a strong political position for Holland within the United Provinces because the province had become the preeminent power in the region after the reconquest of Brabant and Flanders by Spanish forces. As the wealthiest province, Holland contributed nearly 59 percent of the federal budget, and it considered itself entitled to a dominant role after having borne the brunt of the revolt against Spain alongside Zeeland for nearly seven years.12

Oldenbarnevelt, serving as the landsadvocaat (chief minister) of Holland, acted as the province's primary advocate to ensure its individuality and special position were safeguarded against attempts at centralized government. By securing this influence, he aimed to protect the interests of the province that served as the economic engine of the republic, effectively filling the power vacuum left by the decline of previously dominant regions.13
