The party now known as PDP–Laban is the result of a merger between the Partido Demokratiko Pilipino and Lakas ng Bayan. Partido Demokratiko Pilipino (PDP) was founded in 1982 by Aquilino “Nene” Pimentel Jr. and a group of protesters against the authoritarian government of Ferdinand Marcos, the 10th President of the Philippines.

These protesters include the leaders of Davao City and Cagayan de Oro City, such as Zafiro L. Respicio, Rey Magno Teves, Cesar R. Ledesma, Samuel Oceña, Crispin Lanorias and Morgs Cua.
