San Marino is considered to have the earliest written governing documents still in effect, as the Statutes of 1600 are still at the core of its constitutional framework. San Marino was originally led by the Arengo, initially formed from the heads of each family. In the 13th century, power was given to the Grand and General Council. In 1243, the first two captains regent were nominated by the council. Still today, Captains Regent are elected every six months by the council. The legislature of the republic is the Grand and General Council (). The council is a unicameral legislature with 60 members.
