BANGKOK, AUGUST 9

In Bangladesh, weeks of protests against a quota system for government jobs turned into a broad uprising that forced the prime minister to flee the country and resign.

The demonstrations began peacefully last month and were primarily led by students frustrated with the system that they said favored those with connections to the ruling party.

But it turned violent on July 15 as student protesters clashed with security officials and pro-government activists. Former Prime Minister Sheikh Hasina fled this week after the unrest during which nearly 300 people died, including both students and police officers.

Students or other young people have frequently played pivotal roles in popular uprisings that have brought down governments or forced them to change policies. Here are some other major cases:

Gota Go Gama protests in Sri Lanka

Like in Bangladesh, widespread protests in Sri Lanka in 2022 were able to bring down a government, and youth played a key role.

Scattered demonstrations turned into months-long protests starting in March 2022 as an economic crisis worsened in the Indian Ocean island nation, leading to a shortage of fuel, cooking gas and other essentials as well as an extended power outage.

In April, protesters primarily led by university students and other young people occupied an esplanade adjoining President Gotabaya Rajapaksa's office in the capital Colombo, demanding he and his government resign.

More people joined daily, setting up a tent camp dubbed 'Gota Go Gama,' or 'Gota Go Village,' a play on Gotabaya's nickname 'Gota.'

The protest site was peaceful, with organizers offering free food, water, toilets and even medical care for people. Camp leaders, many of whom were university students, held daily media briefings and made regular speeches, while the crowd was entertained by bands and plays.

The government reacted by imposing a curfew, declaring a state of emergency, allowing the military to arrest civilians and restricting access to social media, but were unable to stop the protest.

Under pressure, many ministers resigned but President Rajapaksa and his older brother, Prime Minister Mahinda Rajapaksa remained.

In May, Rajapaksa supporters attacked the protest camp, drawing widespread condemnation from across the country and forcing Prime Minister Rajapaksa to resign.

Gotabaya Rajapaksa clung to power until July, when protesters stormed his official residence, forcing him to flee the country. After taking temporary refuge in the Maldives, Rajapaksa later resigned.

His successor, Ranil Wickremesinghe, in one of his first moves as new president ousted protesters from occupied government buildings and shut down their camp, dismantling their tents in the middle of the night.

The situation has since calmed, and Wickremesinghe has been able to address the shortages of food, fuel and medicine and restore power.

Complaints continue, however, about the rise in taxes and electric bills that are part of the new government's efforts to meet International Monetary Fund loan conditions. Former Prime Minister Rajapaksa's son Namal Rajapaksa will be running in the presidential elections this September.

Athens Polytechnic uprising in Greece

In November 1973, students at Athens Polytechnic university rose up against the military junta that ruled Greece with an iron fist for more than six years.

Military officers seized power in a 1967 coup, establishing a dictatorship marked by the arrest, exile and torture of its political opponents.

The regime's brutality and hardline rule gave rise to a growing opposition, particularly among students, culminating in the November uprising.

The protest began peacefully on Nov. 14, with students staging a strike at the Athens Polytechnic university and occupying the campus. By the next day, thousands from around Athens had joined in to support the students and the demonstrations grew, as did calls to end the dictatorship.

On Nov. 17, the military crushed the revolt when a tank smashed through the university's gates in the early hours of the day, killing several students. The number of fatalities is still disputed, but at the time the regime had announced 15 dead.

Days after the uprising, another military officer staged a coup and implemented an even harsher regime. It was short lived however, after a series of events led to a return to democracy in Greece, its birthplace, in 1974.

A prosecutor's report issued after the return to civilian government, estimated fatalities at 34, but mentioned only 18 names. There were more than 1,100 injured.

Today, annual marches in Athens to commemorate the pro-democracy student uprising still attract thousands of people.

Kent State demonstrations in the United States

American students had long been protesting the U.S. involvement in Vietnam when President Richard Nixon authorized attacks on neutral Cambodia in April 1970, expanding the conflict in an attempt to interrupt enemy supply lines.

On May 4, hundreds of students at Ohio's Kent State University gathered to protest the bombing of Cambodia, and authorities called in the Ohio National Guard to disperse the crowd.

After failing to break up the protest with teargas, the National Guard advanced and some opened fire on the crowd, killing four students and wounding nine others.

The confrontation, sometimes referred to as the May 4 massacre, was a defining moment for a nation sharply divided over the protracted conflict, in which more than 58,000 Americans died.

It sparked a strike of 4 million students across the U.S., temporarily closing some 900 colleges and universities. The events also played a pivotal role, historians argue, in turning public opinion against the conflict in Southeast Asia.

Soweto Uprising in South Africa

In the decades-long struggle against white minority rule in South Africa, a pivotal moment came in 1976 in the Soweto area of Johannesburg.

In a series of demonstrations starting June 16, Black students from multiple schools took to the streets to protest against being forced to study in Afrikaans, the Dutch-based language of the white rulers who designed the system of racial oppression known as apartheid.

The protests spread to other areas in South Africa, becoming a flashpoint for anger at a system that denied adequate education, the right to vote and other basic rights to the country's Black majority.

Hundreds are estimated to have died in the government crackdown that followed.

The bloodshed was epitomized by a photograph of a dying student, Hector Pieterson. The image of his limp body being carried by another teenager was seen around the world and galvanized international efforts to end South Africa's racial segregation, though apartheid would linger for nearly two more decades.

South Africa achieved democracy with majority rule elections in 1994 and today June 16 is a national holiday.

Velvet Revolution in Czechoslovakia

As the Communist governments of Eastern Europe teetered in 1989, widespread demonstrations broke out in Czechoslovakia after riot police suppressed a student protest in Prague on November 17.

On November 20 as the anti-Communist protests grew, the students being joined by scores of others and some 500,000 took to the streets of Prague.

Dubbed the 'Velvet Revolution' for its non-violent nature, the protests led to the resignation of the Communist Party's leadership on November 28.

By Dec. 10, Czechoslovakia had a new government and on Dec. 29, Vaclav Havel, a dissident playwright who had spent several years in prison, was elected the country's first democratic president in a half century by a parliament still dominated by communist hard-liners.

In 1992, Czechoslovakia peacefully split into two countries, the Czech Republic and Slovakia.
