Final answer:
The quote 'Et tu, Brute?– Then fall Caesar.' is spoken by Julius Caesar in Shakespeare's play and reflects Caesar's shock upon seeing his friend Brutus among his assassins. The First Triumvirate included Caesar, Pompey, and Crassus. The Second Triumvirate was formed by Mark Antony, Octavian, and Lepidus.
Step-by-step explanation:
The quote 'Et tu, Brute?– Then fall Caesar.' is a line from William Shakespeare's play Julius Caesar. This line is said by Julius Caesar himself, as he is being assassinated. It is a moment of betrayal, as Caesar is shocked to see his friend Brutus among the conspirators. The historical Caesar's last words are not definitively known, but Shakespeare's portrayal has deeply influenced the image of Caesar's death in popular culture.
The First Triumvirate initially consisted of Julius Caesar, Pompey, and Crassus, three powerful figures in Roman politics who formed an alliance to dominate the Roman political landscape. This triumvirate is important to understanding the events that lead to the rise of Julius Caesar as a dictator and the eventual fall of the Roman Republic.
After Caesar's assassination, the Second Triumvirate was formed by Mark Antony, Octavian (the future Emperor Augustus), and Lepidus, which is a significant chapter in Roman history, as it led to the ultimate collapse of the Republic and the rise of the Roman Empire.
