Husni al-Za'im
Al-Hinnawi overthrew the military rule of Syrian President Husni al-Za'im on August 14, 1949 with the aid of fellow members in the Syrian Social Nationalist Party, including Adib al-Shishakli. After the coup, he swiftly ordered al-Za'im and Prime Minister Muhsin al-Barazi to be brought to Mezze prison in Damascus, where both were executed in front of Muhsin al-Barazi's son.
