Who built the first greek kingdom?

The first Greek kingdom is often attributed to the Mycenaean civilization, which emerged around 1600 BC. This civilization was characterized by its complex palatial states, such as Mycenae, Tiryns, and Pylos. The Mycenaeans were influenced by earlier Minoan culture on Crete and played a significant role in the development of Greek language, art, and trade. Their decline around 1100 BC marked the end of the Bronze Age in Greece.
