Manuel Luis Quezon y Molina (19 August 1878 – 1 August 1944), also known by his initials MLQ, was a Filipino lawyer, statesman, soldier, and politician who served as the second president of the Philippines from 1935 until his death in 1944. He was the first Filipino to head a government of the entire Philippines and is considered the second president of the Philippines after Emilio Aguinaldo (1899–1901), whom Quezon defeated in the 1935 presidential election. Quezon City, a city in Metro Manila and Quezon Province, are named after him.

During his presidency, Quezon tackled the problem of landless peasants. Other major decisions included the reorganization of the islands' military defense, approval of a recommendation for government reorganization, the promotion of settlement and development in Mindanao, dealing with the foreign stranglehold on Philippine trade and commerce, proposals for land reform, and opposing graft and corruption within the government. He established a government in exile in the U.S. with the outbreak of World War II and the threat of Japanese invasion. Scholars have described Quezon's leadership as a "de facto dictatorship" and described him as "the first Filipino politician to integrate all levels of politics into a synergy of power" after removing his term limits as president and turning the Senate into an extension of the executive through constitutional amendments.
