Beginning with the campaigns of Adad-nirari II, Assyria again became a great power, ultimately overthrowing the Twenty-fifth dynasty of Egypt and conquering Elam, Urartu, Media, Persia, Mannea, Gutium, Phoenicia/Canaan, Arabia, Israel, Judah, Philistia, Edom, Moab, Samarra, Cilicia, Cyprus, Chaldea, Nabatea, Commagene, Dilmun, Shutu and Neo-Hittites; driving the Nubians, Kushites and Ethiopians from Egypt; defeating the Cimmerians and Scythians; and exacting tribute from Phrygia among others. Adad-nirari II and his successors campaigned on an annual basis for part of every year with an exceptionally well-organized army. He subjugated the areas previously under only nominal Assyrian vassalage, conquering and deporting Aramean and Hurrian populations in the north to far-off places. Adad-nirari II then twice attacked and defeated Shamash-mudammiq of Babylonia, annexing a large area of land north of the Diyala river and the towns of Hit and Zanqu in mid Mesopotamia. He made further gains over Babylonia under Nabu-shuma-ukin I later in his reign. He was succeeded by Tukulti-Ninurta II in 891 BC, who further consolidated Assyria's position and expanded northwards into Asia Minor and the Zagros Mountains during his short reign.
