Answer:
4: The Khmer Rouge refused to follow a peace agreement established with the United Nations in 1991
Explanation:
The Khmer Rouge is definitely the most terrible thing that has happened to the people of Cambodia, and the worst period was when Pohl Pot was the leader. Around two million people lost their lives, many more were tortured, everything was taken away from the people, and violence was what ruled the country. The Khmer Rouge managed to commit pretty much all crimes against humanity unfortunately. One thing that can not be considered as a violation of the human rights is that it didn't followed the agreement with the United Nations in general, as that is more of a diplomatic issue between two sides.
The 13th, 14th, and 15th Amendments, also collectively known as the Civil War Amendments were designed to ensure equality for recently emancipated slaves. The 13th Amendment banned slavery and all involuntary servitude, except in the case of punishment for a crime.
The 14th Amendment guaranteed African Americans citizenship rights and promised that the federal government would enforce equal protection of the laws.
The 15th Amendment stated that no one could be denied the right to vote based on race, color or previous condition of servitude.
