Margaret Thatcher’s premiership from 1979 to 1990 had a profound impact on Scotland. David Stewart analyzes the impact of this period of Conservative government on Scotland, while examining the extent to which Conservative policy under Thatcher represented a break from the ‘post-war consensus’ in British politics. Focusing on the origins and impact of the poll tax, the campaign to save Ravenscraig steelworks, the sharpening of the North/South divide, the 1984/85 miners’ strike, and the balance of power within Scottish civil society, he makes substantial contributions to the debates surrounding the decline of Scottish Unionism, the roots of Scottish devolution, the legacy of Thatcherism, and the changing British constitution.
