Atlantic slave trade
The Igbo were affected heavily by the Atlantic slave trade in the 18th century. Enslaved Igbo were known for being rebellious and having a high count of suicide in defiance of slavery. In the United States the Igbo were most numerous in the states of Maryland (coincidentally where there is a predominant population of recent Igbo immigrants) and Virginia, so much so that some historians have denominated colonial Virginia as “Igbo land.”
With a total of 37,000 Africans that arrived in Virginia from Calabar in the 18th century, 30,000 were Igbo according to Douglas B. Chambers. The Frontier Culture Museum of Virginia estimates around 38% of captives taken to Virginia were from the Bight of Biafra. Igbo peoples constituted the majority of enslaved Africans in Maryland. Chambers has been quoted saying "My research suggests that perhaps 60 percent of black Americans have at least one Igbo ancestor..."
Virginia was the colony that took in the largest percentage of Igbo slaves. Researchers such as David Eltis estimate between 30—45% of the 'imported' slaves were from the Bight of Biafra, of these slaves 80% were likely Igbo. A so-called conservative estimate of the amount of Igbo taken into Virginia between 1698 and 1778 is placed at 25,000. The Igbo concentration was especially high in the Tidewater and Piedmont regions of the Virginia interior. One of the reasons for this high number of Igbo slaves in Virginia was the domination of the Bight of Biafra region of Africa by Bristol and Liverpool English merchants who frequently brought Bight of Biafra slaves to British colonies, Virginia being one of these colonies. The high concentration of Igbo slaves in Virginia was contributed to further by neighboring states. Planters in South Carolina and Georgia looked down on Igbo slaves because many were rebellious. Because of this the majority of Igbo slaves were taken and sold to Virginian planters.
Some possible Igbo names were also found among slave records in Virginia. Names found in records such as Anica, or Anakey, Breechy and Juba may originate respectively from the Igbo names Nneka, meaning the mother is superior, and mburichi, male members of the Kingdom of Nri and Jiugba, meaning yam barn. Some had their ethnicity added to their names such as Eboe Sarah and plain Ebo. These hints of Igbo influence go along with cultural remnants pointing towards the Igbo presence in Virginia, one of which is the use of the Eboe drum in music. The Igbo presence in Virginia also brought new practices such as the cultivation of Okra, a plant whose name derives from the Igbo language. Slaves in Virginia relied on sweet potato which is argued by Douglas Chambers to be an indication of a substitute for yam, the Igbo staple crop.
The state of Kentucky, which was carved out of the Colony of Virginia had received many of Virginia's slave drivers and slaves as people started migrating westward. These migrations spread out the population of African slaves in America, including Igbo slaves. Here the Igbo population had already become heavily creoleized alongside other African ethnicities that were taken in significant numbers to America.
