Ninoy Aquino Day is a national non-working holiday in the Philippines observed annually on August 21, commemorating the anniversary of the 1983 assassination of former Senator Benigno “Ninoy” Aquino, Jr.. He was the husband of Corazon Cojunagco Aquino, who was later to become Philippine President; both are treated as two of the heroes of democracy in the country. His assassination led to the downfall of the Dictator Ferdinand Edralin Marcos on February 25, 1986, through the People Power Revolution.
Unlike other dates reserved for national heroes of the Philippines (like Bonifacio Day, Rizal Day, Araw ng Kagitingan, and National Heroes Day), the date is not a “regular holiday” but only a “non-working holiday”. (Wikipedia)
Aquino was a well-known opposition figure and critic of the then-President Ferdinand Marcos. Due to his beliefs, he was later imprisoned for about eight years after martial law was declared in the country. Even in his imprisonment, he sought a parliamentary seat for Metro Manila in the Interim Batasang Pambansa, under the banner of the Lakas ng Bayan (LABAN). He eventually led in the opinion polls and was initially leading the electoral count but eventually lost to the Kilusang Bagong Lipunan (KBL) slate led by First Lady Imelda Marcos. Aquino remained in prison but continued to fight for democracy in the country and against the oppression of the Filipino people. After suffering from a heart attack in March 1980, he and his family moved to the United States for medical treatment, eventually leading to his self-imposed exile for about three years. There, he continued his advocacy by giving speeches to the Filipino-American communities. Later, he planned to return to the islands to challenge Marcos for the parliamentary elections in 1984. Though some did not feel this was a good idea, he still did so in 1983. Upon returning to the Philippines at the Manila International Airport (now renamed Ninoy Aquino International Airport in his honor), he was shot and died on August 21, 1983 as he was escorted off an airplane by security personnel. This led to several protests at his funeral that sparked snap presidential elections in 1986, which led to the 1986 EDSA Revolution, catapulting his wife, Cory Aquino, to the presidency.
