Philippines: Massive Anti-Corruption Rallies Set to Hit Manila on September 21
What Is Happening in Manila?
Several groups are preparing demonstrations in Manila on Monday, September 21, as public attention remains focused on allegations of corruption involving government-funded infrastructure and flood-control projects.
The planned protests also fall on the 54th anniversary of the declaration of martial law under former Philippine President Ferdinand Marcos Sr. The date has therefore taken on additional historical significance for groups emphasizing accountability and democratic rights.
Organizers are expected to gather in different locations around Metro Manila, with some groups planning marches toward the Mendiola area near Malacañang, the Philippine presidential palace.
Why Are Protesters Taking to the Streets?
A major issue behind the demonstrations is the controversy surrounding flood-control projects. Allegations have included claims of irregular spending, questionable project implementation and possible misuse of public funds.
The controversy has remained a major political and public issue in the Philippines, with government investigations and criminal proceedings involving several individuals connected to the wider infrastructure controversy.
Protest organizers have said their demonstrations are intended to demand accountability and greater transparency in the handling of public money.
- Major anti-corruption demonstrations are planned for Manila on September 21, 2026.
- The rallies coincide with the 54th anniversary of the 1972 declaration of martial law.
- Flood-control and infrastructure controversies are central issues for several protest groups.
- Organizers have announced activities in different parts of Metro Manila.
- Police authorities have prepared a large security deployment for the demonstrations.
- The Philippine government has urged protesters to keep the gatherings peaceful and orderly.
More Than 15,000 Police Personnel to Be Deployed
The National Capital Region Police Office has announced heightened security preparations ahead of the September 21 demonstrations.
According to the Philippine National Police, more than 15,700 personnel are expected to be deployed for security operations across Metro Manila. Authorities have also said officers involved in crowd-control operations will not carry firearms and will use body-worn cameras.
Police officials said the preparations are intended to protect protesters, commuters, residents and other members of the public while allowing peaceful assemblies to take place.
Authorities Urge Peaceful Demonstrations
The Philippine government has emphasized that citizens have the right to express grievances and participate in peaceful assemblies.
Malacañang has also appealed to participants to avoid violence, stressing that public demonstrations should remain within the law.
The call follows disturbances that occurred during portions of the September 21 protests in 2025, when clashes between some protesters and police resulted in injuries and arrests.
Where Are the Rallies Expected?
Different organizations have announced activities at locations across Metro Manila. One announced gathering is planned around Liwasang Bonifacio, followed by a march toward Mendiola.
Other demonstrations and gatherings are also expected in the wider capital region. Because several groups are involved, the size and exact movement of crowds may change throughout the day.
Authorities have also announced road restrictions and security measures around areas connected to the planned demonstrations.

Previous September 21 Protests
The September 21 demonstrations have a recent history in the Philippines. In 2025, large gatherings were held in Manila and other locations amid public anger over alleged corruption connected to flood-control projects.
Most of the major gatherings were initially reported as peaceful, although serious clashes later occurred in parts of Manila. The incidents led to arrests and injuries among police and protesters.
The events of 2025 have influenced preparations for this year's demonstrations, with authorities announcing a larger security presence and urging participants to avoid confrontation.
What Could Happen on September 21?
The scale of the demonstrations will depend on turnout at the different assembly points and the movement of participating groups during the day.
Authorities are preparing for significant crowds and possible traffic disruption in parts of Metro Manila. Road closures and restrictions are expected around areas affected by the planned activities.
The situation may also develop during the day as organizers, police and local authorities respond to crowd movements and changing conditions.
Why the Flood-Control Issue Matters
Flooding is a serious concern in the Philippines, making the country's flood-control infrastructure especially important to communities vulnerable to heavy rainfall and storms.
Allegations that public funds may have been improperly handled in connection with infrastructure projects have therefore attracted significant public attention.
Government investigations and legal proceedings are continuing, while different political and civic groups have expressed competing views about responsibility, accountability and the appropriate response.
Philippines Anti-Corruption Rallies: The Bottom Line
Manila is preparing for a major day of demonstrations on September 21, 2026. Protest groups are focusing on corruption allegations, flood-control projects and demands for greater public accountability.
The demonstrations coincide with the anniversary of the 1972 declaration of martial law, giving the date additional historical and political significance.
Police have announced a major security operation, while the Philippine government has said peaceful assembly remains a right and urged demonstrators to avoid violence.
