How were the Kurds treated when Saddam Hussein was the leader of Iraq?

Saddam Husein treated his national people terribly. He kept them poor, uneducated and unexposed to the global environment. He would annihilate anyone he felt like killing, even his own family members. He was oppressive and mean. Thousands of of people lost their family members due to his murderous streak. Some people were killed and buried secretly. Many Iraqis have never known what happened to their family members.
