What group in Iraq had the most power under Saddam Hussein?

Under Saddam Hussein, the most powerful group in Iraq was the Ba'ath Party, which he led. The party promoted Arab nationalism and socialism, consolidating power through a network of loyalists and security forces. The Sunni Arab minority, particularly from Saddam's Tikriti clan, dominated key positions in the government and military, marginalizing other ethnic and religious groups, particularly the Shiites and Kurds. This concentration of power contributed to widespread repression and conflict during his regime.
