Micronesian colonists reached the Marshall Islands using canoes circa 2nd millennium BC, with interisland navigation made possible using traditional stick charts. They eventually settled there. Islands in the archipelago were first explored by Europeans in the 1520s, starting with Ferdinand Magellan, a Portuguese explorer in the service of Spain, Juan Sebastián Elcano and Miguel de Saavedra. Spanish explorer Alonso de Salazar reported sighting an atoll in August 1526. Other expeditions by Spanish and English ships followed. The islands derive their name from John Marshall, who visited in 1788. The islands were historically known by the inhabitants as "jolet jen Anij" (Gifts from God).
