In 494 BC the plebians detached and formed their own plebian council. they elected tribunes to protect their rights; with the tribunes they could not vote against unjust laws passed by patricians/the senate. the citizen assembly elected consuls, tribunes, and magistrates, could declare war and ratify peace treaties, and could approve or disapprove laws proposed by the Senate.
