Comprehensive yet accessible, this classic text, now in its thirteenth edition follows the evolution of political thought over 300 years. Organized chronologically, this text examines each ideology within a political, historical, economic, and social context. In addition to a thorough updating of examples and data, here's what you'll find in the new edition:

• Analyses of President Trump's rollback of Obamacare, trade war with China, and changes to immigration, taxation, and environmental policy.
• Conservative justifications for supply-side economics and liberal rationale for drug legalization and trigger-word bans.
• Brexit's effects on the Scottish independence movement.
• Resurgence of feminist protest, including the Me Too movement, alongside anarchist protest, following Trump's election, including groups like Black Bloc and Antifa.
• China's rising environmental and social problems, including unrest among its heavily controlled Uighur population.
• Cuba's transfer of power from the Castros to President Diaz-Canel, and their fraught rapprochement with the U.S.
• Russia's disinformation campaigns, and alternating brinksmanship and detente between Trump and North Korea's Chairman Kim Jong-un.
• The ascent of the Alt-right in the U.S., and white supremacist influence on parties in the U.S. and Europe.
• The continuing salience of Islamism, the teetering Iran deal, and ongoing degeneration of the Arab Spring to the Islamist Winter.
