While not strictly regulated to just Piracy, the term ''Blackbirding'' is implied to be a 19th Century term for the coercion of Native Peoples for the purpose of ''voluntarily'' enslaving or indenturing them into servitude. The term wand practice was more widely seen in The Pacific Ocean and involved many of the smaller islands and native populace.
While Slavery was outlawed (in theory) in England, it still existed in many European Nations – in particularly with Spain and it's New World Colonies. The United States saw no immediate need to contract with ''Agencies'' that specialized in Blackbirding – whereas Slavery was still very much legal within The Southern Region. England did attempt to tacitly enforce anti-slavery and blackbirding on the High Seas, but only within it's Colonial jurisdictions. Rarely did England Board foreign vessels due the immediate causal of War with the particular Country the ship was registered to.
Inducements made to primate tribes (trinkets, promises of food etc), were mostly met without hostilities. By the time the tribe discovered the ''truth'' they were sold into forced labor (mostly working in Sugarcane Fields, Tobacco etc). As a result of this influx of labor, a ''new'' Colony for Spain could develop ''faster'' and thus entice Colonists to move. A 30% increase in immigration from Spain developed in the early 19th Century as a result.
True to form, Pirates and Privateers saw ''investment possibilities'' in blackbirding as well. Often, when a ship was taken ANY ''person'' could be ''pressed'' and ''sold'' – without his consent. Most blackbirding would cease by the 1850s within Pacific Region, but examples continued until the 1890s in some cases.
