Margaret Thatcher (1925-2013) is a real historical figure and Conservative politician who served as Prime Minister of the United Kingdom from 1979 to 1990, during which she implemented policies that emphasized individualism, nationalism, and fiscal conservatism. Her style of rule marked an extreme shift in the style of governance which had become the norm in the U.K. in the decades after World War II. In history and in the novel’s alternate history, she began to see declining support due to inflation and higher unemployment rates. In actual history, she saw renewed support following British victory in the 1982 Falklands War. In the novel’s alternate timeline, however, Thatcher’s popularity takes a massive hit following Britain’s loss of that war, and she is ousted from power when she loses the 1983 election to Labour Party politician Tony Benn.
