Kaifeng is one of the oldest cities in China and one of its seven historical capitals, with a history spanning several millennia. The first settlements at this site, located in the fertile Yellow River valley, appeared as early as the 8th–5th centuries BC. The official founding date of the city is considered to be 364 BC, when the State of Wei made it its capital under the name Daliang. Throughout its long history, the city changed names several times, including Bianliang and Bianjing, before its modern name was established.
A key factor in Kaifeng's development was its strategic geographical position. In the 7th century, the city was connected to the Grand Canal of China, which transformed it into a major trade and logistics hub. However, Kaifeng's true "golden age" occurred during the Northern Song Dynasty (960–1127), when it became the imperial capital. During this time, Kaifeng was not only a political center but also one of the largest economic and cultural hubs in the world, with a population estimated by some to exceed one million people.
During its heyday, Kaifeng was a bustling metropolis. Caravans from the Silk Road passed through its gates, fostering the development of trade and crafts. The city was famous for its culture: poetry, calligraphy, and the production of exquisite ceramics flourished here, examples of which are still considered unsurpassed. It was in Kaifeng that important inventions were made, including movable type printing technology and some of the world's first hydraulic astronomical clocks.
