Ashur-bel-nisheshu

Ashur-bel-nisheshu (1417–1409 BC) seems to have been independent of Mitannian influence, as evidenced by his signing a mutually beneficial treaty with Karaindash, the Kassite king of Babylonia in the late 15th century. He also undertook extensive rebuilding work in Ashur itself, and Assyria appears to have redeveloped its former highly sophisticated financial and economic systems during his reign.
