and agreed to restore him to the English throne. Defeat in the 1649–1651 Third English Civil War or Anglo-Scottish War resulted in Scotland's incorporation into the Commonwealth of England, Scotland and Ireland, largely driven by Cromwell's determination to break the power of the kirk, which he held responsible for the Anglo-Scottish War. The 1652 Tender of Union was followed on 12 April 1654 by An Ordinance by the Protector for the Union of England and Scotland, creating the Commonwealth of England, Scotland and Ireland. It was ratified by the Second Protectorate Parliament on 26 June 1657, creating a single Parliament in Westminster, with 30 representatives each from Scotland and Ireland added to the existing English members. 1660–1707 While integration into the Commonwealth established free trade between Scotland and England, the economic benefits were diminished by the costs of military occupation. Both Scotland and England associated union with heavy taxes and military rule; it had little popular support in either country, and was dissolved after the Restoration of Charles II in 1660. The Scottish economy was badly damaged by the English Navigation Acts of 1660 and 1663 and England's wars with the Dutch Republic, Scotland's major export market. An Anglo-Scots Trade Commission was set up in January 1668 but the English had no interest in making concessions, as the Scots had little to offer in return. In 1669, Charles II revived talks on political union; his motives were to weaken Scotland's commercial and political links with the Dutch, still seen as an enemy and complete the work of his grandfather James I. Continued opposition meant these negotiations were abandoned by the end of 1669. Following the Glorious Revolution of 1688, a Scottish Convention met in Edinburgh in April 1689 to agree a new constitutional settlement; during which the Scottish Bishops backed a proposed union in an attempt to preserve Episcopalian control of the kirk. William and Mary were supportive of the idea but it was opposed both by the Presbyterian majority in Scotland and the English Parliament. Episcopacy in Scotland was abolished in 1690, alienating a significant part of the political class; it was this element that later formed the bedrock of opposition to Union. The 1690s were a time of economic hardship in Europe as a whole and Scotland in particular, a period now known as the Seven ill years which led to strained relations with England. In 1698, the
