What happened 609 AD

In 609, Pope Boniface IV re-dedicated the Pantheon in Rome to "St Mary and all martyrs" on 13 May. This was the same date as Lemuria, an ancient Roman festival of the dead, and the same date as the commemoration of all saints in Edessa in the time of Ephrem.

Despite the loss of almost all of its major cities, and in the face of overwhelming odds, Assyrian resistance continued under Ashur-uballit II (612–609 BC), who fought his way out of Nineveh and coalesced Assyrian forces around Harran which finally fell in 609 BC. The same year, Ashur-uballit II besieged Harran with the help of the Egyptian army, but this failed too, and this last defeat ended the Assyrian Empire.

Sinsharishkun's successor Ashur-uballit II, the final king of Assyria, was defeated at Harran in 609 BC.

This Battle of Megiddo is recorded as having taken place in 609 BC when Pharaoh Necho II of Egypt led his army to Carchemish (northern Syria) to join with his allies, the fading Neo-Assyrian Empire, against the surging Neo-Babylonian Empire. This required passing through territory controlled by the Kingdom of Judah. The Judaean king Josiah refused to let the Egyptians pass. The Judaean forces battled the Egyptians at Megiddo, resulting in Josiah's death and his kingdom becoming a vassal state of Egypt. The battle is recorded in the Hebrew Bible, the Greek 1 Esdras, and the writings of Josephus.
