Passage: Evidence suggests that around 3,000 years ago successive waves of human migrants from Southeast Asia spread across the Western Pacific Ocean, populating its many small islands. The Marshall Islands were settled by Micronesians in the 2nd millennium BC. Little is known of the islands' early history. Early settlers traveled between the islands by canoe using traditional stick charts.The Spanish explorer Alonso de Salazar landed there in 1526, and the archipelago came to be known as "Los Pintados" ("The Painted (Ones)", possibly referring to the autochthonous people first found there), "Las Hermanas" ("The Sisters") and "Los Jardines" ("The Gardens") within the Spanish Empire. It first fell within the jurisdiction of the Viceroyalty of New Spain, and was then administered by Madrid, through the Captaincy General of the Philippines, upon the independence of Latin America and the dissolution of New Spain starting in 1821.
