Granada, which soon became part of the Umayyad-ruled Muslim Andalusia in the early eighth century, emerged as an independent kingdom in the aftermath of the collapse of Umayyad rule and was subsequently formed the part of Zirid, Almoravid and Almohad rulers and became the seat of power of the Nasrid rulers in the early part of the 13th century which lasted till the closing part of the 15th century. Under the Nasrid rulers, Granada registered multiple strides in socio-economic realms along with progress in art, architecture and culture and Alhambra fort and palace complex is the unique legacy of Medieval Islamic architecture.
