Born in 85 BC, he was known for his philosophical leanings and was a follower of Stoicism. Brutus's involvement in the conspiracy against Caesar was driven by his belief in the Republic and the fear of tyranny. Despite his noble intentions, the assassination led to a series of civil wars that ultimately ended the Roman Republic. Brutus's legacy is complex; he is often remembered as both a traitor and a hero, embodying the struggle between personal loyalty and civic duty.
