The May 1 riots or EDSA Tres was a protest sparked by the arrest in April 2001 of newly deposed President Joseph Estrada of the Philippines. The protest was held for seven days in a major highway in Metropolitan Manila, the Epifanio de los Santos Avenue or EDSA, which eventually culminated in an attempt to storm the Malacañang presidential palace. Taking place four months after EDSA Revolution of 2001, the protests were asserted as a more populist and representative uprising in comparison to the previous demonstrations in the same location, in January 2001. The protests and the attack on the presidential palace, however, failed in their objectives. Participants continue to claim that it was a genuine People Power event, a claim disputed by the participants and supporters of EDSA II. President Gloria Macapagal-Arroyo has acknowledged the divisive nature of the two terminologies by saying in one statement that she hoped to be the president of "EDSA II and EDSA III."

The crowd of an alleged several hundred thousand people (although according to Eagle Broadcasting Corporation-owned broadcast network Net 25 and to Senator Sotto, a high of over 3 million in the evening of April 30), most of whom were members of the urban poor and devotees of the Iglesia ni Cristo which institutionally supported Estrada, gathered at the Roman Catholic EDSA Shrine, the site of the January EDSA II revolt which had toppled Estrada from the presidency.

News organizations aiming to cover the rally were advised not approach the area, as there were reports of stones being thrown at cameramen, particularly those from ABS-CBN.

The protest was led by members of the political opposition of the time, most notably Senators Juan Ponce Enrile, Vicente Sotto III, Gringo Honasan, Panfilo Lacson and Miriam Defensor-Santiago.
