🏛️Intro to Ancient Rome Unit 8 – Julius Caesar: Fall of the Roman Republic

Julius Caesar's rise to power marked a pivotal moment in Roman history. As a skilled general and charismatic leader, he transformed the political landscape, challenging the traditional power structures of the Roman Republic. His military conquests in Gaul and his formation of the First Triumvirate with Pompey and Crassus set the stage for his eventual dictatorship. Caesar's assassination on the Ides of March triggered a series of events that led to the fall of the Republic. The power vacuum left by his death sparked renewed civil conflict, ultimately resulting in the rise of Octavian (Augustus) and the establishment of the Roman Empire. Caesar's legacy continues to influence political thought and popular culture to this day.
