The island of St. Martin owes its name to the explorer Christopher Columbus, who sighted the island on November 11, 1493, during his second voyage to the Americas. November 11 is the feast day of St. Martin of Tours, a 4th-century Roman soldier turned bishop known for his humility and for famously sharing his cloak with a beggar. Following the tradition of naming discoveries after the saint of the day, Columbus christened the land "Santo Martino." Before the arrival of Europeans, the indigenous Carib and Arawak populations called the island "Soualiga" (Land of Salt) or "Oualichi" (Land of Brave and Beautiful Women). Today, the name reflects the island's dual heritage, divided into the French "Saint-Martin" and the Dutch "Sint Maarten," a partition that has existed peacefully since the 1648 Treaty of Concordia.
