The area was so named due to the high volume of enslaved people transported from its shores, profoundly impacting both the local societies and the broader Atlantic world.
A significant number of these individuals, likely more than half, were embarked from the beach south of Ouidah, which lacked formal port facilities.
[6] While most European personnel either died or returned home after short tenures, those who stayed longer often formed relationships with local women and had children.
[12][13] Ports that exported these enslaved people from Africa include Ouidah, Lagos, Aného (Little Popo), Grand-Popo, Agoué, Jakin, Porto-Novo, and Badagry.
[citation needed] The transatlantic slave trade in West Africa began to decline earlier than in other regions.
[16] Most powerful slave-trading countries had begun abolitionist campaigns in 1807, while the volume of slave shipments began to decline in West Africa from 1787.
[16] This was due to colonial legislation creating favorable circumstances for abolition and greater economic opportunities, such as the cash crop revolution, empowering former slaves.
[16] The coast was also called "the White man's grave"[17][18] because of the mass amount of death from illnesses such as yellow fever, malaria, heat exhaustion, and many gastro-entero sicknesses.
[31] After the institution of slavery was abolished by successive European governments, the transatlantic slave trade continued for a time, with independent traders operating in violation of their countries' laws.
Historian Ana Lucia Araujo has noted that the process of enslavement did not end with arrival on Western Hemisphere shores; the different paths taken by the individuals and groups who were victims of the trans-Atlantic slave trade were influenced by different factors—including the disembarking region, the ability to be sold on the market, the kind of work performed, gender, age, religion, and language.
