Rise to Power after Alexander’s Death
After Alexander died in 323 BCE, his empire was left without a clear successor. Perdiccas became the regent. Seleucus supported Perdiccas initially.

When Perdiccas faced military failures, Seleucus joined a conspiracy to assassinate him around 321 BCE. This move elevated Seleucus’s status among Alexander’s generals.
Wars of the Diadochi
Following Perdiccas’s death, the Wars of the Diadochi erupted among Alexander’s successors. Seleucus was appointed Satrap of Babylon in 321 BCE at the Partition of Triparadisus. However, conflict soon resumed. Antigonus, a powerful general, forced Seleucus to flee Babylon.
With Ptolemy I Soter‘s support, Seleucus returned to Babylon in 312 BCE. He then expanded his territories ruthlessly, conquering Persia and Media. Seleucus secured control over the eastern regions of Alexander’s empire.
