Passage: In 1250, the Mamluks seized control of Egypt from the Ayyubids, and by 1261 had managed to assert themselves in Syria as well their most famous ruler was Baibars. The Mamluks were not, strictly speaking, a dynasty, as they did not maintain a patrilineal mode of succession; in fact, Mamluks were freed Turkish and Caucasian slaves, who (in theory) passed the power to others of like station. This mode of government persevered for three centuries, until 1517, and gave rise to abundant architectural projects (many thousands of buildings were constructed during this period), while patronage of luxury arts favored primarily enameled glass and metalwork, and is remembered as the golden age of medieval Egypt.  The "Baptistère de Saint-Louis" in the Louvre is an example of the very high quality of metalwork at this period.
