Kanakas were workers from various Pacific Islands employed in British colonies, such as British Columbia (Canada), Fiji, Solomon Islands, Vanuatu, Papua New Guinea, and Queensland (Australia) in the 19th and early 20th centuries. They also worked in California and Chile.

Blackbirding is the coercion of people through deception or kidnapping to work as slaves or poorly paid labourers in countries distant from their native land. The practice took place on a large scale with the taking of people indigenous to the numerous islands in the Pacific Ocean during the 19th and 20th centuries. These blackbirded people were called Kanakas or South Sea Islanders. They were taken from places such as Papua New Guinea, the Solomon Islands, Vanuatu, Niue, Easter Island, the Gilbert Islands, Tuvalu, Fiji, and the islands of the Bismarck Archipelago amongst others.
