The Yellow River (Huang He) in China is prone to a great deal of flooding. The 1887 Yellow River floods devastated the area, killing between 900,000-2,000,000 people. It was one of the deadliest natural disasters ever seen. For centuries, people living near this river had built dikes to contain the rising waters, caused by silt accumulation on the riverbed.

In 1887, the rising riverbed, coupled with heavy rain fall, overcame the dikes, causing a great flood. It was generally thought that the Yellow River broke through the dikes in Huayankou, near the city of Zhengzhou in Henan province. Owing to the low-lying plains in the area, the flood spread quickly throughout Northern China, covering an estimate 50,000 square miles, swamping agricultural settlements and commercial centers. After the flood, two million were left homeless. The resulting pandemic and lack of basic essentials directly claimed as many lives as the flood itself. But, in 1931, greater floods killed over 4 million.
