President Aquino envisioned agrarian and land reform as the centerpiece of her administration's social legislative agenda. However, her family background and social class as a privileged daughter of a wealthy and landed clan became a lightning rod of criticisms against her land reform agenda. On 22 February 1987, three weeks after the resounding ratification of the 1987 Constitution, agrarian workers, and farmers marched to the historic Mendiola Street near the Malacañan Palace to demand genuine land reform from Aquino's administration. However, the march turned violent when Marine forces fired at farmers who tried to go beyond the designated demarcation line set by the police. As a result, at least 12 were killed and 51 protesters were injured in this incident now known as the Mendiola Massacre. This incident led some prominent members of the Aquino Cabinet to resign their government posts.
