Miguel López de Legazpi, also known as El Adelantado and El Viejo, was a Spanish conquistador who financed and led an expedition to conquer the Philippine islands in the mid-16th century. He was joined by Guido de Lavezares, relative Martin de Goiti, friar Andrés de Urdaneta, and his grandsons Juan and Felipe de Salcedo, in the expedition. Legazpi established the first Spanish settlement in the East Indies after his expedition crossed the Pacific Ocean, arriving in Cebu in 1565. He became the first Governor-General of the Spanish East Indies, which was administered from New Spain for the Spanish crown. It also encompassed other Pacific islands, namely Guam, the Mariana Islands, Palau, and the Carolinas. After obtaining peace with various indigenous tribes and kingdoms, he made Cebu City the capital of the Spanish East Indies in 1565 and later transferred to Manila in 1571. The capital city of the province of Albay bears his name.

The governor-general of the Philippines was the title of the government executive during the colonial period of the Philippines, governed by Mexico City and Madrid (1565–1898) and the United States (1898–1946), and briefly by Great Britain (1762–1764) and Japan (1942–1945). They were also the representative of the executive of the ruling power.
