The population of San Marino is comprised of native Sammarinese and Italian citizens. Crop farming, sheep farming, and the working of stone from the quarries formed the early backbone of San Marino's economy. It has no mineral resources, and today most of the land is cultivated or covered by woods.
According to tradition, San Marino was founded in AD 301 when a Christian stonemason named Marinus the Dalmatian fled to the island of Arbe to escape the anti-Christian Roman Emperor Diocletian. Marinus hid on the peak of Mount Titano and founded a small community of people following their Christian beliefs. It is certain that the area had been inhabited since prehistoric times, although evidence of existence on Mount Titano only dates back to the Middle Ages. In memory of the stonecutter, the land was renamed "Land of San Marino" and was finally changed to its present-day name, "Republic of San Marino."
