The Mamluk dynasty existed from approximately 1250 to 1500 A.D. The Mamluks were slave soldiers who earned their freedom and became rulers of a dynasty which lasted 250 years. Their rulers were known for patonage of the arts, thus this was the most prolific and influential period for Islamic art. Mamluk metalware is recognizeable by the repeated cartouches and medallions and the chain patterns encircling the pieces. Copper and silver inlay into brass pieces is also commonly found.
