San Marino (/ˌsæn
The country derives its name literally from Saint Marinus, a stonemason originating from the Roman colony on the island of Rab, in modern-day Croatia. In AD 257,[clarification needed] Marinus, according to legend, participated in the reconstruction of Rimini's city walls after their destruction by Liburnian pirates. Marinus then went on to found an independent monastic community on Monte Titano in AD 301; thus, San Marino lays claim to be the oldest extant sovereign state as well as the oldest constitutional republic.
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, or constitution, still in effect.
The country's economy mainly relies on finance, industry, services and tourism. It is among one of the wealthiest countries in the world in terms of GDP (per capita), with a figure comparable to the most developed European regions. San Marino is considered to have a highly stable economy, with one of the lowest unemployment rates in Europe, no national debt and a budget surplus, and has the world's highest rate of car ownership, being the only country with more vehicles than people.
San Marino is one of the only three countries (the others being Vatican City, also surrounded by Italy, and Lesotho) in the world to be completely surrounded by a single other country. It is the third smallest country in Europe, with only Vatican City and Monaco being smaller. It is also the fifth smallest country in the world.
