# Coastwise slave trade

The coastwise slave trade existed along the southern and eastern coastal areas of the United States in the antebellum years prior to 1861. Hundreds of vessels of various capacities domestically traded loads of slaves along waterways, generally from the Upper South which had a surplus of slaves to the Deep South where new cotton plantations created high demand for labor.
International tensions developed when ships were forced by weather or incident into ports in Bermuda and the British West Indies, as the British freed the slaves as part of the banned trade on the high seas, even before its abolition of slavery in its territories in 1834. There were several cases: Comet (1830), Encomium (1833), Enterprise (1835), Hermosa (1840), and, most notably, the Creole case of 1841, the result of a ship slave revolt that forced the vessel into Nassau, Bahamas. British officials freed the 128 slaves who chose to stay in the Bahamas.

## Legal rights

Prior to 1807, the 1787 United States Constitution and the 1793 Fugitive Slave Act were the only national United States laws on slavery. Individual states had enacted laws authorizing and regulating slavery within their boundaries.
The multi-faceted 1807 Act Prohibiting Importation of Slaves abolished the "importation of slaves" from Africa, effective in 1808. The United States and Great Britain patrolled to create an international Blockade of Africa, trying to suppress the slave trade. In addition, American and British ships patrolled the Caribbean, where illegal slaves were generally brought for sale to the sugar plantations and smuggling into the United States.
The 1807 Act also regulated the United States' "coastwise slave trade"; it protected shipping by domestic slave traders between markets along the other slave trading coasts. Attorneys argued that ships at sea were an extension of United States sovereignty, which permitted domestic slave trade among the states.

## Conflict between the United States and Britain in the Caribbean

Complications developed between the United States and Great Britain from their differing interpretations of the application of laws against the slave trade in the Caribbean colonies. When American merchant ships were forced by weather or incident into ports in Bermuda and the British West Indies, the British freed the slaves as part of the banned trade on the high seas, even before its abolition of slavery in its territories in 1834. As early as 1825, the Home Office in London had ruled that "any slave brought to the Bahamas from outside the British West Indies would be manumitted, which led to 300 slaves owned by U.S. nationals being freed." In addition, slaves who escaped to the Bahamas from Florida became free.
Several cases occurred as anti-slavery agitation increased and abolition was passed: Comet (1830), Encomium (1833), Enterprise (1835), and Hermosa (1840) In each case, the British freed the slaves from the ships that had put into ports in Bermuda and the Bahamas, whether by weather or accident.
The most notable case was the 1841 Creole, the result of a ship slave revolt that forced the vessel into Nassau, Bahamas. One of the slave leaders had heard of slaves being freed from the Hermosa there the previous year.
Holding that the slaves were free persons illegally detained in slavery, British officials ultimately freed the 128 of 135 slaves from the Creole who chose to stay in the Bahamas. It has been termed the "most successful slave revolt in U.S. history". The US slaveholders feared this would encourage other slave ship revolts.

## Cabotage

The act of sailing along a coast and using landmarks for guidance is called cabotage, from the French word caboter ("to coast," "go from cape to cape"). When slaves were the merchandise being transported by cabotage, the practice was called the coastwise slave trade.
