Did Greeks invent the chariot

Answer 1

No. They had been around for a couple of thousand years in the Middle East before Rome became more than a village.

Although the Latins are recorded early on as using chariots (see Aeneid), the Romans adopted mainly infantry tactics, and quickly learned to neutralise chariots, so they quickly disappeared from the Italian battlefield. The Hellenistic kingdoms in the east persiated with chariots for an extra century or so but learnt that they were a liability against the Roman countermeasures.

Answer 2

The ancient Egyptians did not invent Chariots, but the did greatly improved them. The Chariot was introduced to the Egyptians by the Hyksos.

Answer 3

No they did not. They were invented by the Sumerians, before the Greek days.
