Greece has a long history dating back to ancient civilizations like the Minoans and Mycenaeans. The Minoans arose on Crete around 2700 BC and had a advanced, trade-based civilization until around 1450 BC. The Mycenaeans settled in Greece around 2000 BC and were influenced by Minoan culture, eventually dominating Crete after 1400 BC. Their empire lasted until 1200 BC when the Dorians invaded. Sparta later emerged as a powerful city-state in the 9th century BC, known for its military focus and social system where male citizens underwent rigorous training. Sparta was a dominant military power until 371 BC and played a major role in the Greco-Persian Wars
