The document discusses the history of terrorism in three stages. It begins by summarizing a New Yorker article describing the shock experienced by Muslims after the defeat of the Ottoman Empire in World War I and the abolition of the Islamic caliphate in the early 20th century. This created a sense of humiliation that continues to influence the Muslim world. It then discusses how the author plans to study the history of terrorism to better understand the present and move toward peace in the future. The summary provides context on some early groups considered terrorist, including Jewish Zealots resisting Rome, the Hashashin assassins of the 11th century, and European pirates of the 16th-18th centuries.
