@WomanCorn Feudalism was neither the first form of government nor even a worldwide form. Feudalism was limited mostly to medieval Europe, so it didn't really exist prior to the 9th century Europe.
Contrast this with the first governments (Sumer and Egypt) which arose around 3000 BCE, about 4,000 years earlier than feudalism, which never really made it to that region at all. They were largely monastic.
