  1. Background

    The Macedonian king's sudden death left a succession crisis, and commanders and satraps competed for royal authority and territory.

    • The king’s sudden death created a succession crisis without an uncontested adult heir
    • Generals and satraps competed over royal authority and territorial assignments
    • Politics in regions from Babylon to the Mediterranean became tightly connected

  2. Course

    Regents and generals alternated between treaties and wars, while Ptolemaic Egypt, the Seleucid realm in Syria and western Asia, and Antigonid Macedonia took shape.

    • Regents and commanders alternated between agreements and armed conflict
    • The Triparadeisos settlement rearranged satrapies and military appointments
    • Dynastic bases consolidated around Egypt and Syria
    Commanders confer over a map at a dry camp council with horses and supply carts nearby

  3. Outcome

    After the Battle of Ipsus in 301 BCE, imperial unity had disappeared and several dynastic states stood across the eastern Mediterranean and western Asia.

    • Imperial unity was lost after Ipsus in 301 BCE
    • Ptolemaic, Seleucid, and Antigonid dynasties stood alongside one another
    • Cities and courts supported regional administration and exchange

  4. Historical significance

    Political fragmentation helped create a Hellenistic world in which Greek language, cities, trade, and royal patronage circulated across regions without erasing local traditions.

    • Greek language and urban institutions mediated long-distance exchange
    • Dynastic competition overlapped with local traditions rather than erasing them
    • The Hellenistic world became a space of simultaneous fragmentation and connection
