Diosdado Macapagal

Macapagal defeated incumbent President Carlos P. Garcia in the 1961 Philippine presidential election, running under the Liberal Party. His campaign focused on anti-corruption and economic reform, and he won with a platform promising change from the nationalist policies of Garcia.

President Macapagal issued Proclamation No. 28 moving the celebration of Philippine Independence Day from July 4 (the date of U.S. recognition of independence in 1946) to June 12 (the date of Emilio Aguinaldo's declaration of independence from Spain in 1898). This act aimed to assert national identity and correct historical inaccuracy.

Macapagal formally revived the Philippine claim to the territory of Sabah (North Borneo), asserting that it was part of the Sultanate of Sulu and thus belonged to the Philippines. This claim led to diplomatic tensions with Malaysia and the United Kingdom, and remains unresolved.

Macapagal signed the Agricultural Land Reform Code (Republic Act No. 3844) into law, aiming to abolish tenancy and establish owner-cultivatorship. The law provided for the expropriation of large estates and redistribution to tenant farmers, though implementation was limited and faced resistance from landowners.

Macapagal lost his re-election bid to Senate President Ferdinand Marcos. The election was marked by Marcos's effective campaign and Macapagal's perceived failure to fully implement land reform and address economic issues, leading to a decisive defeat.
