The Erlitou culture was an early Bronze Age society and archaeological culture. It existed in the Yellow River valley from approximately 1900 to 1500 BC. The culture is named after Erlitou, an archaeological site in Yanshi, Henan. It was widely spread throughout Henan and Shanxi and later appeared in Shaanxi and Hubei. Most archaeologists consider Erlitou the first state-level society in China. Chinese archaeologists generally identify the Erlitou culture as the site of the Xia dynasty, but there is no firm evidence, such as writing, to substantiate such a linkage, as the earliest evidence of Chinese writing dates to the Late Shang period.

The Shang dynasty, also known as the Yin dynasty, was a Chinese royal dynasty that ruled in the Yellow River valley during the second millennium BC, traditionally succeeding the Xia dynasty and followed by the Western Zhou dynasty. The classic account of the Shang comes from texts such as the Book of Documents, Bamboo Annals and Records of the Grand Historian. Modern scholarship dates the dynasty between the 16th and 11th centuries BC, with more agreement surrounding the end date than beginning date.
