@theforgottenautho: The Longshan Culture-China's Forgotten Bronze Age Predecessor Before China's first dynasty, an advanced culture built walled cities and vanished. Around 3000 BC, China's Longshan culture built walled settlements and produced remarkably advanced pottery, centuries before the Shang Dynasty, traditionally considered China's first confirmed dynasty. Evidence suggests organized labor and early social hierarchy already existed. The culture mysteriously declined before 1900 BC, for reasons still debated by archaeologists. Why do you think earlier cultures like this get so little recognition compared to the dynasties that followed them? #ancientcivilizations #longshanculture #chinesehistory #hiddenhistory #historicalmysteries
