During the Neo-Assyrian Empire (911–605 BC) Nineveh grew in size and importance, particularly from the reigns of Tukulti-Ninurta II and Ashurnasirpal II (883–859 BC) onward; he chose the city of Kalhu (the Biblical Calah, modern Nimrud) as his capital in place of the ancient traditional capital of Aššur (Ashur), 30 kilometers from present day Mosul.
