August Twenty-One Movement (ATOM) Under the administration of President
Ferdinand Marcos, Agapito was one of the founders of the August Twenty-One Movement (ATOM), Coalition of Organizations for the Restoration of Democracy (CORD) and Bansang Nagkakaisa sa Diwa at Layunin (BANDILA). Agapito became close friends with Binay as co-founders.
KOMPIL In January 1984, Aquino established with the aid of the CPP the Kongreso ng Mamamayang Pilipino (KOMPIL), which aimed to unite the opposition against the Marcos administration.
Bayan In May 1985, upon the establishment of the
Bagong Alyansang Makabayan (or Bayan), Aquino was elected to its National Council. After two weeks, however, Aquino resigned from the council with
Teofisto Guingona Jr., with the two being reportedly uneasy about the growing influence of the CPP and its
National Democratic Front (NDF) in the alliance. Aquino thus formed a new organization with Guingona called Bansang Nagkaisa sa Diwa at Layunin (BANDILA; ), and by August 4, 1985 he launched another group called the Filipino Social Democratic Movement (FSDM) at a convention within the
Ateneo de Manila University, with Mar Canonigo as secretary general. In a conversation with journalist
Gregg Jones that same month, Aquino claimed that the CPP had been attempting to impose itself on how the composition of Bayan's national council should be during its first congress, and that while he had permitted the CPP to utilize him in the past, he vowed to no longer associate with the party: "
Diokno,
Tañada and I worked with them in trust. For us, that trust was broken at the Bayan national congress." Aquino thus went directly to
Camp Aguinaldo for Enrile and Ramos' second press conference and proceeded to offer his support, with Enrile answering: "We need all the support we can get." Some hours after Aquino and Sin broadcast their messages, several soldiers attacked and destroyed the station's transmitter. On February 25, 1986, three days after Aquino and Sin's broadcast, the movement spread nationwide and became known as the
People Power Revolution (also called the EDSA Revolution), managing to remove the Marcos family from government and install
Corazon Aquino as the new
president of the Philippines. ==Political career==
