Peace was declared on 15 April 1654 with the signing of the Treaty of Westminster. Cromwell's sole condition was that he required Dutch agreement that no Prince of Orange or other member of the House of Orange should hold the office of Stadtholder or any other public office in the Netherlands, a demand that was strongly opposed by Orangists. Although this was not part of the formal peace treaty, the Treaty of Westminster, the two members of the negotiating team from the province of Holland agreed to a secret annexe providing that England would only would ratify the treaty after the States of Holland had passed an Act of Seclusion, excluding the House of Orange from holding public office in that province: this legislation was passed in May 1654. There was an adverse reactions from several of other Dutch provinces, but their provincial assemblies could neither overcome their own internal divisions nor coordinate opposition with other provinces. However, although they did not enact their own Exclusion legislation then, in practice they did not oppose it. Only after the Second Anglo-Dutch War did four other provinces besides Holland adopt the Perpetual Edict (1667) sanctioning Exclusion.
