This book is a combination of three works by a Roman historian and politician, focusing on the political and military events of the late Roman Republic. It first covers the conspiracy led by Catiline in 63 BC, then shifts to the war against Jugurtha in North Africa, and finally provides a fragmentary history of Rome from 78-67 BC. The author uses these events to critique the moral decay of Rome, highlighting the corruption, greed, and ambition that he believed led to the fall of the Republic.

The book is a profound exploration of European imperialism and the roots of genocide, blending travelogue, personal diary, and historical analysis. The narrative delves into the dark history of colonialism, examining how racist ideologies were used to justify the extermination and subjugation of non-European peoples under the guise of civilization and progress. Through a series of interwoven reflections and accounts, the author confronts the violence and atrocities committed by European powers in Africa and beyond, challenging readers to acknowledge and understand the brutal legacy of colonialism that has shaped the modern world.
