The document discusses Mexico's role in the Spanish conquest and colonization of the Philippines from 1565 to 1821. It notes that the Legazpi expedition that conquered the Philippines was patronized by Mexican authorities, funded by Mexico, and manned by Mexican soldiers and sailors. Without Mexico's additional support of troops, missionaries, and supplies, the expedition would not have succeeded. The Philippines was then ruled from Mexico by the Mexican viceroy on behalf of the Spanish king for over 250 years. During this time, there was frequent exchange between the colonies, including trade, migration of people, and spread of culture and religion.
