In the history of Tuamotu, the Tuamotus were first discovered by a Spanish expedition led by Ferdinand Magellan in 1521. From the Inca Empire, Tupac Inca Yupanqui is also credited with leading a nearly 10-month voyage of exploration into the Pacific around 1480. None of these visits were of political consequence, the islands being in the sphere of influence of the Pomare dynasty of Tahiti.
