Seleucus 1 Nicator (1 jul 323 año aC – 30 jun 312 año aC)

Descripción:

Alexander's generals (the Diadochi) jostled for supremacy over parts of his empire. Ptolemy, a former general and the satrap of Egypt, was the first to challenge the new system; this led to the demise of Perdiccas. Ptolemy's revolt led to a new subdivision of the empire with the Partition of Triparadisus in 320 BC.
Seleucus, who had been "Commander-in-Chief of the Companion cavalry" (hetairoi) and appointed first or court chiliarch (which made him the senior officer in the Royal Army after the regent and commander-in-chief Perdiccas since 323 BC, though he helped to assassinate him later) received Babylonia and, from that point, continued to expand his dominions ruthlessly. Seleucus established himself in Babylon in 312 BC, the year used as the foundation date of the Seleucid Empire.
