The Cambodian genocide was a very dark time in history. It happened between 1975 and 1979 in the country of Cambodia. A group called the Khmer Rouge took control of the land. Their leader was a man named Pol Pot. This group wanted to turn the whole country into a farm-based society. They wanted everyone to live in the countryside and work the land. 
To reach their goals, the Khmer Rouge made many hard choices. They forced people to leave big cities. They marched citizens into labor camps in the countryside. Life in these camps was very difficult for everyone. People suffered from hunger, disease, and hard work. Many people were also killed by the group.
The Khmer Rouge did not act alone. They received a lot of help from China. The Chinese Communist Party supported Pol Pot for many years. In 1975 alone, China gave at least US$1 billion in aid. This aid included money and weapons for the military. Pol Pot even traveled to Beijing to meet with leader Mao Zedong. 
The numbers from this time are very large and sad. Between 1.2 and 2.8 million people died during the genocide. This was about 15 to 36 percent of all people in Cambodia. Many different groups of people were targeted. This included 200,000 to 300,000 Chinese Cambodians and many Cham people. Some people were even taken to a place called the Killing Fields. 
Eventually, the Khmer Rouge lost their power. The Vietnamese military invaded in 1978 and stopped the regime. Later, the world worked to find justice for what happened. In 2003, a special court was set up. It was called the Extraordinary Chambers in the Court of Cambodia. This court held trials for the leaders of the Khmer Rouge. Some leaders, like Nuon Chea and Khieu Samphan, were sent to prison for life. 
The Cambodian genocide was a period of systematic persecution and mass killing. It occurred between 1975 and 1979 in Cambodia. The Khmer Rouge, a radical political group, held total power during this time. Their leader was Pol Pot, who served as the general secretary. The regime aimed to transform Cambodia into an agrarian socialist republic. This meant they wanted a society based entirely on farming and manual labor. They were heavily influenced by ultra-Maoism and the Chinese Cultural Revolution. 
The path to power began with a civil war and political instability. In 1970, Premier Lon Nol deposed King Norodom Sihanouk. This established the Khmer Republic, which was supported by the United States. Sihanouk later formed an alliance with the Khmer Rouge while in exile. This alliance helped the Khmer Rouge grow from 6,000 to 50,000 fighters. Meanwhile, the United States conducted a massive bombing campaign in Cambodia from 1970 to 1973. Some historians believe this devastation helped the Khmer Rouge gain more local support. On April 17, 1975, the Khmer Rouge captured the capital city, Phnom Penh. 
The Khmer Rouge regime operated through strict control and forced movement. After seizing power, they emptied the large cities immediately. They forced citizens to march into the countryside to join labor camps. In 1976, they officially renamed the country Democratic Kampuchea. The government sought to eliminate modern influences to focus on agriculture. This process involved widespread indoctrination and the abduction of children. Many children were forced to participate in the regime's violent actions. Life in the countryside was defined by forced labor and constant fear.
Conditions within the country were extremely brutal for the population. Many people died from malnutrition, exhaustion, and various diseases. The Khmer Rouge also operated a network of 196 different prisons. One famous site was Security Prison 21, also known as Tuol Sleng. Out of 20,000 prisoners who passed through that specific prison, only seven adults survived. Prisoners were often taken to sites known as the Killing Fields. There, they were executed and buried in mass graves. 
The scale of the loss of life was massive and reached many groups. It is estimated that between 1.2 and 2.8 million people died. This represented 15% to 36% of Cambodia's total population in 1975. The deaths included 200,000 to 300,000 Chinese Cambodians and 90,000 to 500,000 Cham people. They also killed 20,000 Vietnamese Cambodians. Direct executions accounted for up to 60% of the total death toll. The genocide also caused a large number of refugees to flee to Thailand and Vietnam.
Foreign support played a major role in the Khmer Rouge's ability to rule. The Chinese Communist Party, led by Mao Zedong, provided significant help. At least 90% of the foreign aid received by the Khmer Rouge came from China. In 1975 alone, China provided at least US$1 billion in interest-free aid. This included both economic support and military assistance. High-ranking Chinese officials even visited Cambodia to offer help to the regime. This international backing helped sustain the Khmer Rouge during their rule.
The regime finally collapsed when the Vietnamese military invaded in 1978. This invasion toppled the Khmer Rouge and ended the massacres by early 1979. In the years following, the world sought legal accountability for these crimes. In 2003, the Cambodian government and the United Nations created a special court. This was known as the Extraordinary Chambers in the Court of Cambodia. The tribunal began trials in 2009 to prosecute the Khmer Rouge leadership. 
Several high-ranking leaders were eventually held responsible for their actions. In 2010, Kang Kek Iew was convicted of crimes against humanity. He was sentenced to life imprisonment by the Supreme Court Chamber. Later, in 2014, Nuon Chea and Khieu Samphan were also convicted. The court found them guilty of crimes against humanity and grave breaches of the Geneva Conventions. They were also found guilty of genocide against the Vietnamese and Cham groups. Both men received sentences of life imprisonment for their roles in the genocide.
