Forced labour, or unfree labour, is any work relation, especially in modern or early modern history, in which people are employed against their will with the threat of destitution, detention, or violence, including death or other forms of extreme hardship to either themselves or members of their families.

The Burma Railway, also known as the Siam–Burma Railway, Thai–Burma Railway and similar names, or as the Death Railway, is a 415 km (258 mi) railway between Ban Pong, Thailand, and Thanbyuzayat, Burma. It was built from 1940 to 1943 by South East Asian civilians abducted and forced to work by the Japanese and a smaller group of captured Allied soldiers, to supply troops and weapons in the Burma campaign of World War II. It completed the rail link between Bangkok, Thailand, and Rangoon, Burma. The name used by the Japanese Government was Tai–Men Rensetsu Tetsudō (泰緬連接鉄道), which means Thailand-Burma-Link-Railway.
