The Christmas Flood of the Netherlands
In 1717, a massive storm hit the coast of the Netherlands, Germany, and Scandinavia. Floodwaters began to rise drastically, faster than anyone could compensate for, and soon whole villages and towns became engulfed. Dams and dykes were breached by the force of the water and storm, and the floods continued all throughout the usually cheery holiday. By the end of it, an estimated 13,000 people or more were drowned by the flooding, and others were killed by debris and disease that came later. Some towns were so badly destroyed that there was nothing left, and they simply ceased to exist.
