The Crusaders: the enemies of Islam:

In 927 AH/1521 AD, the vanguard of the crusaders arrived at the Philippines islands from the east under the command of Ferdinand Magellan, the Portuguese explorer, in an attempt to encircle the Muslim world.
Once Magellan arrived at the Philippines, he began his Christian proselytizing efforts, sometimes by force, using weapons that were unknown to the peoples of these islands. He resorted to temptation at other times to lure Muslims into Christianity.

He reached an agreement with Rajah Humabon, the ruler of Cebu Island that he converts into Catholicism and in return he would be appointed the king of all the islands under the authority of the Spanish Crown. Then, Ferdinand Magellan moved to the rest of the islands to solidify the rule of his friend Humabon and to preach Christianity.
Magellan reached a small island, Mactan that was ruled by a Muslim ruler named "Lapu-Lapu".

The Spaniards resorted to terrorism in order to convert the Muslims of that island into Christianity. They set their huts on fire, stole their money, destroyed their livelihood, and chased their women. Lapu-Lapu resisted their terrorism and sabotage and refused to surrender to Magellan. He even urged the rest of the islands to rebel against the Spanish invaders. Lapu-Lapu attacked Magellan and killed him and refused to give his body to the Spaniards. After the killing of Magellan, Spain sent four successive campaigns to conquer the Philippines but all ended in failure.
