Caesar wanted to be consul but he didn't know how to get money to become consul.
I what to be consul but how am I going to get enough money?
Caesar saw the two richest people in town, Pompey and Crassus, and started the First Triumvirate because they were all in need of something. Crassus had arranged for his wealthy friends to collect taxes, Pompey joined to makes sure that his soldiers would stay loyal to him, and Caesar became concul but later because governer of Gaul
I was wondering if you guys could donate some money to me?
We all need something so we should all give each other what we want.
The Triumvirate ended in 50 B.C due to Crassus dying in a battle and Pompey was jealous of Caesar's military success and his popularity.
