Originally published in 1962, this is the final volume of Party Politics following Appeal to the People and The Growth of Parties, which appeared in 1960 and 1961. In it Sir Ivor Jennings analyses the nature of politics by discussing some of the political ideas such as Church and King, liberty, nationalism, imperialism, free trade and the welfare state, which were instrumental in shaping the British political system. The three volumes of Party Politics complete the survey of British political institutions which Sir Ivor Jennings began with Parliament and Cabinet Government. At the time of publication these volumes formed the standard twentieth century authority on British Constitutional history, law and practice.
