The Rajahnate of Cebu was a native kingdom which used to exist in Cebu prior to the arrival of the Spaniards. It was founded by Sri ‘Lumay’ otherwise known as ‘Rajamuda Lumaya’, a native prince of the Chola dynasty which had invaded Sumatra in Indonesia. He was sent by the Maharajah to establish a base for expeditionary forces to subdue the local kingdoms, but he rebelled and established his own independent Rajahnate instead.
The arrival of Portuguese explorer Ferdinand Magellan in 1521 established a period of Spanish exploration and colonization.
Losing favor for his plan of reaching the Spice Islands from king Manuel I of Portugal, by sailing west from Europe, Magellan offered his services to king Charles I of Spain. On September 20, 1519, Magellan led five ships with a crew of 250 people from the Spanish fort of Sanlúcar de Barrameda en route to Southeast Asia via the Americas and Pacific Ocean. They reached the Philippines on March 16, 1521. RajahKolambu the king of Mazaua told them to sail for Cebu, where they could trade and have provisions.
