Hattushili made the city of Hattusa the capital of that kingdom. After Hattushili I, a new king arose: Murshili I (1630 - 1600 BCE). He ruled the state in peace and tranquility, expanding its borders as far as the seas. He made a successful military expedition to Halep and Babylon. But the king was murdered. Then his successor Hantili I came to the throne. Around this time, attacks by the Hurrians resulted in chaos within the country.
