After serving as a senator from 1992 to 1998, she was elected to the vice presidency under President Joseph Estrada, despite having run on an opposing ticket.
After Estrada was accused of corruption, she resigned her cabinet position as Secretary of Social Welfare and Development and joined the growing opposition to the president, who faced impeachment.
Estrada was soon forced out from office by the Second EDSA Revolution in 2001, and Arroyo was sworn into the presidency by Chief Justice Hilario Davide, Jr. on January 20.
In 2003, the Oakwood mutiny occurred after signs of a martial law declaration were seen under her rule.

A 2010 leaked diplomatic cable from the United States
stated that Arroyo's administration was 'corrupt', even worse than Ferdinand Marcos's, and that Arroyo's husband, Jose Miguel Arroyo, is 'one of the most corrupt'.
Following her presidency, she was elected to the House of Representatives through her home district, which was her last bailiwick, making her the second Philippine president—after José P. Laurel—to pursue a lower office after their presidency.
On November 18, 2011, Arroyo was arrested following the filing of criminal charges against her for electoral fraud.
She was held at the Veterans Memorial Medical Center in Quezon City under charges of electoral sabotage but released on bail in July 2012.
She was rearrested on charges of misuse of $8.8 million in state lottery funds in October 2012.
She was given a hospital arrest allegedly due to "life-threatening health conditions" certified by her doctors.
On July 19, 2016, she was acquitted by the Supreme Court by a vote of 11-4 under the administration of her ally, Rodrigo Duterte.
Also, the Supreme Court declared the DOJ's hold departure order unconstitutional.
Her lawyers afterwards stated that Arroyo no longer needed her medical paraphernalia, releasing her from the hospital.
She has since been a member of the Philippine Academy of the Spanish Language after she announced her support to bring back Spanish as an official language of the Philippines during her 9-year presidency.
