Qatar General Post Office Issue for the Golden Age Scientists.

The Islamic Golden Age is the era in the history of Islam, traditionally between the 8th and 14th century.

During much of this period, most of the Islamic world was ruled by caliphates. Science, economic development and cultural works flourished.

This period is understood to have began during the reign of Abbasid caliph Hard Al Rashid (788 to 809) with the inauguration of the 'house of wisdom' in Baghdad. Scholars from all over the Islamic World were mandated to gather and translate the world's classic literature into Arabic.

The period is thought to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the Siege of Baghdad in 1258.
