Term limits, age requirements, the election of two consuls instead of one, and the ability of magistrates to veto each other, to name a few examples, all served the purpose of preventing one person from amassing too much power.

Detailed explanation-2: -The Senate was the governing and advisory assembly of the aristocracy in the ancient Roman Republic. It was not an elected body, but one whose members were appointed by the consuls, and later by the censors.
