What happened 745 AD

Tiglath-Pileser III was a prominent king of Assyria in the eighth century BCE (ruled 745–727 BCE) who introduced advanced civil, military, and political systems into the Neo-Assyrian Empire.

After the reign of Adad-nirari III, Assyria entered a period of instability and decline, losing its hold over most of its vassal and tributary territories by the middle of the 8th century BC, until the reign of Tiglath-Pileser III (745–727 BC). He created the world's first professional army, introduced Imperial Aramaic as the lingua franca of Assyria and its vast empire, and reorganized the empire drastically. Tiglath-Pileser III conquered as far as the East Mediterranean, bringing the Greeks of Cyprus, Phoenicia, Judah, Philistia, Samaria, and the whole of Aramea under Assyrian control. Not satisfied with merely holding Babylonia in vassalage, Tiglath-Pileser deposed its king and had himself crowned king of Babylon. The imperial, economic, political, military, and administrative reforms of Tiglath-Pileser III were to prove a blueprint for future empires, such as those of the Persians, Greeks, Romans, Carthaginians, Byzantines, Arabs, and Turks.
