Abid Hamid Mahmud al-Tikriti was a close associate of Saddam Hussein and served as his personal secretary and adviser. He held significant power within the Iraqi government and was one of Hussein's most trusted loyalists. Mahmud was known for his role in the Ba'ath Party and was involved in various aspects of the regime's administration and security apparatus.

Their relationship was characterized by deep loyalty, and Mahmud was often seen as a key figure in Saddam's inner circle, especially during the 1980s and 1990s. After the fall of Saddam's regime in 2003, Mahmud was captured by U.S. forces and later tried for crimes against humanity, highlighting the extent of his involvement in the oppressive actions of the Iraqi government under Saddam Hussein.
