Abd al-Karim Qasim
In February 1958, King Hussein of Jordan and `Abd al-Ilāh proposed a union of Hāshimite monarchies to counter the recently formed Egyptian–Syrian union. The resulting Arab Federation, formed on 14 February 1958, was short-lived. It ended in 1958, when the monarchy was overthrown in a military coup, led by Abd al-Karim Qasim.
