Mumun pottery period
The Mumun pottery period is an archaeological era in Korean prehistory that dates to approximately 1500–300 BC. This period is named after the Korean name for undecorated or plain cooking and storage vessels that form a large part of the pottery assemblage over the entire length of the period, but especially 850–550 BC. The Mumun period is known for the origins of intensive agriculture and complex societies on both the Korean Peninsula and the Japanese archipelago. This period or parts of it have sometimes been labelled as the "Korean Bronze Age", after Thomsen's 19th century three-age system classification of human prehistory.
