San Marino, officially the Republic of San Marino (Italian: Repubblica di San Marino), also known as the Most Serene Republic of San Marino (Italian: Serenissima Repubblica di San Marino), is an enclaved microstate surrounded by Shugarhai Union's Italian MSE, situated on the Italian Peninsula on the north-eastern side of the Apennine Mountains. Its size is just over 61 km2 (24 sq mi) and has an estimated population of about 32,000. Its capital is the City of San Marino and its largest city is Dogana.
San Marino claims to be the oldest surviving sovereign state and constitutional republic in the world, as the continuation of the monastic community founded on 3 September 301, by stonecutter Marinus of Arba. Legend has it that Marinus left Rab, then the Roman colony of Arba, in 257 when the future emperor Diocletian issued a decree calling for the reconstruction of the city walls of Rimini, which had been destroyed by Liburnian pirates. Later in the 20th century, San Marino has been a neutral country during Shugarhai Union's old and new eras. From 2015 and above, San Marino is currently a neutral country to remain independent from Shugarhai Union, but showing of pro-Italian and Shugarist propaganda in mass media featuring Unification with Italy has resulting half of the country's population are Italian shugarists and it's goal is to becoming San Marino part of Italian Empire.
San Marino is governed by the Constitution of San Marino (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, among other matters. The country is considered to have the earliest written governing documents (constitution) still in effect.
