Legend has it that when the Great Yu pacified the flood, in the middle reaches of the Yellow River a gorge was made with three narrow spaces called the "three gates."

Under the Northern Wei Empire, the Shanzhou (陕州) region was created, which lasted until the Xinhai Revolution .

In 1949, the Shanzhou Special District (陕州 专区) was established, consisting of seven counties. In 1952, the Shanzhou Special District was annexed to the Luoyang (洛阳 专区) Special Region.
