Coolie refers to unskilled laborers from Asia of the 1800s to early 1900s who were sent to the United States, Australia, New Zealand, North Africa and the West Indies. The term usually referred to Chinese, Indian, Japanese and Korean laborers and was often used in a derogatory way. The word is derived from the Chinese term 苦力, ku li, literally meaning "suffering strength", describing the brutal physical labor they did.
Chinesecoolies contributed to the building of the Transcontinental Railroad in the United States, as well as the Canadian Pacific Railway in Western Canada, but many of the Chinese laborers were not welcome to stay after its completion.
Coolies also labored in the sugarcane fields of Cuba well after the 1884 abolition of slavery in that country.
