The Grand Canal of China is completed

609 CE

The Sui emperor Yang, working with millions of conscripted labourers, linked and enlarged existing waterways between 605 and 609 to create the Grand Canal, connecting the Yellow River in the north with the Yangtze valley and Hangzhou in the south. Later extended to Beijing, it reached some 1,800 km and is the longest artificial waterway in the world. It moved rice to the capital and bound together the north and south of China. The cost in lives and taxes helped bring down the Sui dynasty in 618. The canal is still partly used today.
