Much is uncertain concerning the Kassites, we know little about their culture as well as where they came from. One of the most likely suggestions is that their origin was in the Zagros Mountains in today’s Iran.
The horse was a sacred animal among the Kassites, and they probably introduced this animal into Mesopotamia.
There is little in art and architecture that was specific to Kassite. Most of what the Kassites built was Babylonian in style — their only intention was to use molded bricks to create relief decorations in temple walls.
Among the modern peoples that seem to descend from the Kassites is the Lors of Iran.
18th century BCE: The Kassites try to penetrate into Babylonia, but are driven out by the king. Still, they manage to establish themselves in Mesopotamia north of Babylonia’s borders.
Middle 18th century: Gandash becomes the first king among the Kassites, a dynasty that eventually would take over Babylonia.
Around 1600: The Kassites take control over Babylonia, and their king becomes king over Babylonia as well. From this followed a 400 year period of Kassite domination in Babylonia.
1158: The Elamites conquer Babylonia, and loot the cities. This becomes the end of the Kassite dynasty.
