A wildlife corridor, habitat corridor, or green corridor is an area of habitat connecting wildlife populations separated by human activities or structures (such as roads, development, or logging). This allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding and reduced genetic diversity (via genetic drift) that often occur within isolated populations. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to random events (such as fires or disease). This may potentially moderate some...

The Polish Corridor (German: Polnischer Korridor; Polish: Pomorze, Polski Korytarz), also known as the Danzig Corridor, Corridor to the Sea or Gdańsk Corridor, was a territory located in the region of Pomerelia (Pomeranian Voivodeship, eastern Pomerania, formerly part of West Prussia), which provided the Second Republic of Poland (1920–1939) with access to the Baltic Sea, thus dividing the bulk of Germany (Weimar Republic) from the province of East Prussia. The Free City of Danzig (now the Polish city of Gdańsk) was separate from both Poland and Germany. A similar territory, also occasional...

The Nordic race is one of the putative sub-races into which some late-19th to mid-20th century anthropologists divided the Caucasian race, attributing them to Northwestern and Northern Europe, particularly to populations such as Anglo-Saxons, Germanic peoples, Balts, Baltic Finns, Northern French, and certain Celts and Slavs. The supposed physical traits of the Nordics included light eyes, light skin, tall stature, and dolichocephalic skull; their psychological traits were deemed to be truthfulness, equitability, a competitive spirit, naivete, reservedness, and individualism. Other supposed...

The Spanish expression la Raza ('the people' or 'the community'; literal translation: 'the race') has historically been used to refer to the Hispanophone populations (primarily though not always exclusively in the Western Hemisphere), considered as an ethnic or racial unit historically deriving from the Spanish Empire, and the process of racial intermixing of the Spanish colonizers with the indigenous populations of the Americas and enslaved Africans brought there by the Atlantic slave trade.The term was in wide use in Latin America in the early-to-mid-20th century, but has gradually been replaced...

Indentured servitude is a form of labor in which a person (an indenture) agrees to work without salary for a specific number of years through a contract for eventual compensation or debt repayment. Historically, it has been used to pay for apprenticeships, typically when an apprentice agreed to work for free for a master tradesman to learn a trade (similar to a modern internship but for a fixed length of time, usually seven years). Later it was also used as a way for a person to pay the cost of transportation to colonies in the Americas. Like any loan, an indenture could be sold; most employers...

Blackbirding involves the coercion of people through deception or kidnapping to work as slaves or poorly paid labourers in countries distant to their native land. The term has been most commonly applied to the large-scale 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 the Solomon Islands, Vanuatu, Niue, Easter Island, Gilbert Islands, Tuvalu and the islands of the Bismarck Archipelago amongst others. The owners, captains and crew...

Indentured servitude in British America was the prominent system of labor in British American colonies until it was eventually overcome by slavery. During its time, the system was so prominent that more than half of all immigrants to British colonies south of New England were white (mostly Irish) servants, and that nearly half of total white immigration to the Thirteen Colonies came under indenture. By the beginning of the American Revolutionary War in 1775, only 2 to 3 percent of the colonial labor force was composed of indentured servants.The consensus view among economic historians and economists...
