New Spain, officially the Viceroyalty of New Spain, originally the Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain. It was one of several domains established during the Spanish conquest of the Americas, and had its capital in Mexico City. Its jurisdiction comprised a large area of the southern and western portions of North America, mainly what is now Mexico and the Southwestern United States, but also California, Florida and Louisiana; Central America, the Caribbean, and northern parts of South America; several Pacific archipelagos, most notably the Philippines and Guam. Additional Asian colonies included "Spanish Formosa", on the island now known as Taiwan.

The Philippines, officially the Republic of the Philippines, is an archipelagic country in Southeast Asia. In the western Pacific Ocean, it consists of 7,641 islands, with a total area of 300,000 square kilometers, which are broadly categorized in three main geographical divisions from north to south: Luzon, Visayas, and Mindanao.
