On March 6, 1521, three
Spanish ships under the command of
Fernão de Magalhães (Ferdinand Magellan) land on the
Island of Guam after a seemingly endless eleven week voyage across the
Pacific Ocean. Magalhães names the archipelago Las Isles de las Velas Latinas (The Islands of the Latine Sails). When the Spaniards refuse to pay for supplies, natives take iron from the ships. Magalhães renames the archipelago Las Islas de los Ladrones (The Islands of the Thieves).
The
Spanish-Chamorro Wars (1670-1683 on Guam) pacifies CHamoru resistance and solidifies Spanish control
Guam becomes a major stopover for
Spanish galleons en route to Manila, from
Acapulco. A number of coastal forts are built to protect these ships, including
Fort Soledad and Fort San Jose in
Umatac.
