In the widely revised and updated third edition of this important work on political ideologies, Andrew Heywood provides a clear and accessible introduction to the political doctrines and beliefs that have dominated and shaped global politics for over 200 years.

Written from an international perspective and ranging from the traditional ideologies of the 19th century, such as liberalism, conservatism, and socialism to more contemporary ones like feminism, environmentalism, and political Islam, it offers a clear exposition of both the historical evolution of each ideology and the impact each has had on modern political movements, parties, and contemporary governance.

The distinct ideas and values of various ideologies are highlighted, along with the competing, and sometimes conflicting, traditions they have created.

This new edition includes new frameworks that analyze the key contrasts within each ideology. It also assesses the prospects of ideologies in the 21st century, while focusing on the impact generated for political ideology and the major ideological traditions by developments such as globalization, the advance of postmodernity and 'post-isms', as well as changes in the global order, including the emergence of global terrorism.
