Widely regarded as Islam's Golden Age, the Abbasid Caliphate was best known for its immense contributions to science, literature, and religion. Modern Cameras, Algebra, Air Conditioner, 1001 Nights, Modern Medicine, Qandil Lamp, Water Clock, Irrigation Methods, and so so much more were all invented during the Abbasid Caliphate. Along with an intelligence surveillance network, massive cross-continental trade routes, and a sophisticated taxation system, the Abbasid Caliphate lasted nearly 500 years.
