Concilio Populi
The Concilio Populi (Anglish: The Council of the People) is the higher chamber of the federal legislative branch of the Sanctum Imperium Catholicum. Ancient records from the First Salvian Imperium date its first establishment in the late 5th century BC, however it did not exist in its modern form until the end of the People's War in 1709 and was largely absent from the Salvian government following its dissolution by the Second Salvian Imperium in the third century AD.
History
The Concilio Populi was originally created in 470s BC, where records of it begin. It had the job of creating and passing new laws and signing treaties with foreign powers, however was subject to the monarch, who, at any time he pleased, could overrule the laws or any other action by them without council.
It existed in this form for the First Imperium until its quick dissolution by the Second Salvian Imperium around 267 AD. It wouldn't be refounded until the nation's new Constitution reinstated it in 1709, with the first elections being held in 1710.
