The rule of Saddam Hussein was a dictatorship. Saddam Hussein was the ruthless dictator of Iraq for over two decades, until he was deposed in 2003.
Two measures that he took as a dictator are:
The invasion of Kuwait in 1990, which is a much smaller country to the south of Iraq. This invasion started the Gulf War, in which the United States participated, and was crucial in the eventual Iraqi defeat.
The brutal crackdown on popular uprisings in 1991, which led to the deaths of thousands of Kurdish People and Shia Muslim.
