Saddam Hussein joined the revolutionary Baath party when he was a university student. In 1958 he had the head of Iraq, Abdul-Karim Qassim, killed. Since 1979 he has been President of Iraq. Under his reign Iraq fought a decade-long war with Iran. Because of his steady enmity with extreme Islamic leaders the West supported him first of all, until his army invaded Kuwait in August 1990, an incident that the USA led to the Gulf War. Since then many rumors about a coup d'état have been launched, but Saddam Hussein is still in unrestricted power.
