The Saudi flag is deeply rooted in the history of the Saudi state since its founding in the eighteenth century. It has undergone several stages through official institutions as follows:

The banner of the First Saudi State, since the time of Imam Mohammed Bin Saud, was green, made from silk and wool, with the phrase "There is no God but Allah and Muhammad is the Messenger of Allah" written on it.
