Final answer:
The First Triumvirate consisted of Julius Caesar, Pompey, and Crassus, formed to forward their individual goals and significantly shaped Roman politics.
Step-by-step explanation:
The members of the First Triumvirate were: Julius Caesar, Pompey, and Crassus. This alliance was formed in 60 BCE to advance the political and personal interests of the three Roman leaders. Each had specific objectives: Caesar was seeking military command and glory in Western Europe, Crassus desired to lead campaigns against Parthia, and Pompey sought recognition and land for his troops. Following Crassus's death and Caesar's increasing popularity, Pompey aligned with the Senate against Caesar, leading to a civil war that ended with Pompey's defeat. The First Triumvirate was therefore a crucial event that led to significant political and military upheaval in the late Roman Republic.
