Why did Johan van Oldenbarnevelt support the Twelve Years’ Truce with Spain?

Johan van Oldenbarnevelt supported the Twelve Years’ Truce primarily because he believed the independence and security of the United Provinces had been sufficiently established to justify a reduction in the immense financial expenditures required by the war against Spain.1

Under his leadership, the province of Holland sought to move away from the heavy costs of the conflict. When Spain agreed to treat the United Provinces as an independent and sovereign power—falling just short of formal recognition—and dropped its demands for guarantees regarding Dutch Catholics, Oldenbarnevelt viewed the terms as a viable path toward peace.1

Furthermore, Oldenbarnevelt’s support for the truce was tied to his broader political vision. He and the regents of Holland favored a state that maintained authority over the church and promoted religious tolerance to facilitate trade, whereas opponents of the truce, including Maurice of Nassau and strict Calvinist clergy, feared that peace would diminish their influence and compromise the religious objectives of the revolt.12
