World’s oldest constitutional republic

San Marino on the Italian peninsula claims to be the oldest constitutional republic in the world as the continuation of the monastic community founded on 3 September 301 by stonecutter Marinus of Arba. It is governed by the Leges Statutae Republicae Sancti Marini, a series of six books written in Latin in the late 16th century, that dictate the country’s political system. The country is considered to have the earliest written constitution still in effect.
