The Sandugo was a blood compact, performed in the island of Bohol in the Philippines, between the Spanish explorer Miguel López de Legazpi and Datu Sikatuna the chieftain of Bohol on March 16, 1565, to seal their friendship as part of the tribal tradition. This is considered as the first treaty of friendship between the Spaniards and Filipinos. "Sandugo" is a Visayan word which means "one blood".
The Battle of Mactan (Cebuano: Gubat sa Mactan; Filipino: Labanan sa Mactan) was a fierce clash fought in the Philippines on 27 April 1521. The warriors of Lapulapu, a native chieftain in Mactan, overpowered and defeated a Spanish force fighting for Rajah Humabon of Cebu under the command of Portuguese explorer Ferdinand Magellan, who was killed in battle. The outcome of the battle resulted in the departure of the Spanish crew from the archipelago, and delayed the Spanish colonization of the Philippines by 44 years until the conquest by Miguel López de Legazpi in 1564–1565.
