The short answer
EDSA II began as an impeachment crisis and ended with a change of president. Mass protest, cabinet resignations and the military’s withdrawal of support brought Gloria Macapagal Arroyo to office; the Supreme Court then held that Joseph Estrada had resigned and that the succession was constitutional.

How did an impeachment trial become a street crisis?
Joseph Estrada won the presidency in 1998 with a large populist mandate. In October 2000, Governor Luis “Chavit” Singson publicly accused him of receiving illegal gambling proceeds and diverted tobacco-tax funds. The allegations rapidly moved from political controversy to constitutional process.
The House transmitted articles of impeachment to the Senate, where a televised trial began. On 16 January 2001, the Senate voted 11–10 not to open a sealed envelope that prosecutors said contained important evidence. The prosecution panel walked out and public confidence in completing the case through the trial collapsed.
What happened at EDSA?
Protesters gathered around the EDSA Shrine after the envelope vote. Political leaders, civil-society organisations, religious figures and media networks helped sustain a mobilisation that borrowed the location and symbolism of the 1986 People Power Revolution.
Cabinet resignations and the withdrawal of support by the armed forces and national police on 19 January transformed the balance of power. The next day, Chief Justice Hilario Davide Jr. administered the presidential oath to Vice President Gloria Macapagal Arroyo, and Estrada left the presidential palace.
Was EDSA II a revolution or a constitutional succession?
Estrada argued that he had not resigned and that Arroyo was at most an acting president. In Estrada v. Desierto, the Supreme Court examined his public statements, final acts and departure, concluding that he had resigned and that Arroyo had become president under the Constitution.
The Court distinguished EDSA I, which it described as an extra-constitutional revolution that replaced the old order, from EDSA II, which it treated as an exercise of speech and assembly within the existing constitutional framework. That legal classification remains central to understanding the succession.
Why does EDSA II remain contested?
Supporters view EDSA II as a legitimate response to failed accountability and presidential loss of authority. Critics argue that street mobilisation, elite realignment and military withdrawal displaced a leader chosen by a national election before the impeachment court reached a verdict.
Both perspectives point to a real institutional tension. The succession was upheld through constitutional interpretation, yet it also depended on forces outside the courtroom and legislature. Later mobilisation by Estrada supporters and continuing disputes over legitimacy showed that a legal ruling could stabilise office without producing universal political consent.
