What happened 323 AD

After the death of Alexander, his empire was, after quite some conflict, divided among his generals, resulting in the Ptolemaic Kingdom (Egypt and adjoining North Africa), the Seleucid Empire (the Levant, Mesopotamia, and Persia), and the Antigonid dynasty (Macedonia). In the intervening period, the poleis of Greece were able to wrest back some of their freedom, although still nominally subject to Macedon.

The conquests of Alexander the Great marked the beginning of a new era in the history of the entire Near East, including regions inhabited by Arameans.

Following the conquest of Bactria by Alexander the Great in 323 BC, for about two centuries Greek was the administrative language of his Hellenistic successors, that is, the Seleucid and the Greco-Bactrian kingdoms.

Perdiccas appointed Ptolemy, one of Alexander's closest companions, to be satrap of Egypt. Ptolemy ruled Egypt from 323 BC, nominally in the name of the joint kings Philip III and Alexander IV.

On either 10 or 11 June 323 BC, Alexander died in the palace of Nebuchadnezzar II, in Babylon, at age 32.

Alexander, who quickly conquered the Persian Empire under its last Achaemenid dynast, Darius III, died young in 323 BC, leaving an expansive empire of partly Hellenised culture without an adult heir. The empire was put under the authority of a regent in the person of Perdiccas, and the territories were divided among Alexander's generals, who thereby became satraps, at the Partition of Babylon, all in that same year.
