The Aegean civilization refers to the Bronze Age cultures of Greece surrounding the Aegean Sea, notably the Minoan civilization on Crete and the Mycenaean civilization on the Greek mainland. The Minoans thrived with advanced city structures and trade until around 1250 BCE, while the Mycenaeans, known for their warrior society, began their decline around 1200 BCE, leading to the eventual rise of ancient Greece. Key features of these civilizations include architectural innovations, religious practices, and a rich cultural legacy that influenced subsequent Greek culture and society.
