Schliemann excavated the ancient Greek city of Mycenae in 1874, finding artifacts that showed a civilization thriving between 1600-1100 BC. Many artifacts were discovered in unique bee-hive shaped burial tombs filled with spoils of war. While the Mycenaeans had a written language called Linear B deciphered in the 1950s, it revealed little about their culture. Major Mycenaean influence was also found in Tiryns, Athens, Orchomenus, and Thebes. Around 1200 BC, all major Mycenaean cities were burned, likely due to warfare, and people began abandoning the cities around 1150 BC, signaling the collapse of the Mycenaean civilization.
