blood compact
Sanduguan was an ancient ritual in the Philippines intended to seal a friendship or treaty, or to validate an agreement. The contracting parties would cut their wrists and pour their blood into a cup filled with liquid, such as wine, and drink the mixture.
A famous example of the blood compact was the 1565 Sandugo between Spanish explorer Miguel López de Legazpi and Datu Sikatuna, the chieftain of Bohol. Another blood compact was done between the Portuguese explorer Ferdinand Magellan and Rajah Humabon of Cebu.
