Nova Scotian Settlers: The Nova Scotian Settlers or Sierra Leone Settlers (also known as the Nova Scotians or more commonly as the Settlers) were African Americans who founded the settlement of Freetown, Sierra Leone on March 11, 1792.  The majority of these black immigrants were among 3000 former slaves and free African Americans who sought refuge with the British during the American Revolutionary War, known as the Black Loyalists.  The Nova Scotian settlers were jointly led by former soldier Thomas Peters and English abolitionist John Clarkson.  For most of the 19th century the Settlers resided in Settler Town and remained a distinct ethnic group within the country.

African-American teachers: African-American teachers educated African Americans and taught each other to read during slavery in the South.  Slaves ran small schools in secret, since teaching a slave to read was a crime (see Slavery in the United States#Slave codes).  While, in the North, African Americans worked alongside with Whites.  Many privileged African Americans in the North wanted their children taught with White children, and were pro-integration.  The Black middle class preferred segregation.  During the post-Reconstruction era African Americans built their own schools so they didn't have White control.  The Black middle class believed that it could provide quality education for their community.  This resulted in the foundation of teaching as a profession for Blacks.  Some Black families had multiple individuals who dedicated their lives to teaching.  They felt that they could empower their communities.  In the late 19th and early 20th centuries, Southern States passed Jim Crow laws to mandate racial segregation in all aspects of society, and prevent Blacks from voting.  Racism made it difficult for Black professionals to work in other professions.  In 1950, African American teachers made up about half of African-American professionals.

Beninese Americans: Beninese American are Americans of Beninese descent.  According to the census of 2000, in the United States there are only 605 Americans of Beninese origin.  However, because in the first half of the eighteenth century many slaves were exported from Benin to the present United States, the number of African Americans with one or more Beninese ancestors could be much higher.  So, the number of slaves from Bight of Benin exported to present United States exceeded 6,000 people, although this might consist not only in Benin, but also washes the shores of Ghana, Togo and Nigeria.  It is also important to note that they were slaves from modern Benin (along with the Haitian immigrants arrived in the United States in the late nineteenth century), who planted voodoo in Louisiana.  Currently, there Beninese communities in cities such as Chicago or Washington D.C and in other states as New York.

Book of Negroes: The Book of Negroes is a historical document that records names and descriptions of 3,000 Black Loyalists, the African-American slaves who escaped to the British lines during the American Revolution and were evacuated to points in Nova Scotia as free people of colour.

John Ball (clergyman): John Ball was an African American Methodist preacher in Shelburne, Nova Scotia.  John Ball is recorded in the Book of Negroes as one of the 3000 African Americans who escaped to the British lines during the American Revolution.

Sierra Leonean Americans: Sierra Leonean Americans are Americans who are descended from Sierra Leoneans.  The population of Sierra Leonean Americans is relatively large and consists, according to surveys of 2013, of 21,538 people.  However, many African Americans are descended also from Sierra Leonean slaves who were exported to the United States since the 18th until the early 19th century, so the number of people with that heritage should be much higher.  So, the number of slaves from present Sierra Leone exported to present United States exceeded the 25.000 people.  A peculiar group of people of partially Sierra Leonean descent in United States is that of the Gullah, who, descendants of slaves, fled their owners at the end of the 18th and early 19th century and they established in parts of South Carolina, Georgia, and the Sea Islands, areas in which, even today, they retain their cultures.  Moreover, according to the American Community Survey there are 34,161 Sierra Leoneans immigrants living in United States.

Atlanta race riot: The Atlanta race riot of 1906 was a racist pogrom in Atlanta, Georgia (United States), which began the evening of September 22 and lasted until September 24, 1906.  It was characterized at the time by "Le Petit Journal" and other media outlets as a "racial massacre of negroes".  The death toll of the conflict is to this day unknown and disputed, but "officially" at least 25 African Americans along with two confirmed European Americans; Unofficial reports ranged from 10 -100 African Americans and 2 European Americans were killed during the riots.  According to the Atlanta History Center, some African Americans were hanged from lamposts during the actual riot.  The main cause of the race riot was newspaper-publicized rapes of four white women in separate incidents, allegedly by African American men.

Cameroonian Americans: Cameroonian American are Americans of Cameroonian descent.  According to the census of 2010, in the United States there were 16,894 Americans of Cameroonian origin.  Many people from present-day Cameroon arrived in the United States as slaves during the antebellum period.  Consequently, many African Americans today have discovered through DNA analysis that they are mainly or at least partly descended from Cameroonian slaves.  The American DNA Company discovered that many of the 6,000 African Americans whose DNA they analyzed had at least one ancestor from current-day Cameroon.  In addition, according to the 2007-2011 American Community Survey there are 33,181 Cameroonian-born people living in the United States.

Port Royal Experiment: The Port Royal Experiment was a program begun during the American Civil War in which former slaves successfully worked on the land abandoned by planters.  In 1861 the Union liberated the Sea Islands off the coast of South Carolina and their main harbor, Port Royal.  The white residents fled, leaving behind 10,000 black slaves.  Several private Northern charity organizations stepped in to help the former slaves become self-sufficient.  The result was a model of what Reconstruction could have been.  The African Americans demonstrated their ability to work the land efficiently and live independently of white control.  They assigned themselves daily tasks for cotton growing and spent their extra time cultivating their own crops, fishing and hunting.  By selling their surplus crops, the locals acquired small amounts of property.  In 1862, General Ormsby M. Mitchel helped African Americans to found the town of Mitchelville on Hilton Head Island.  In 1865 President Andrew Johnson ended the experiment, returning the land to its previous white owners.

Edisto Island during the American Civil War: Edisto Island during the American Civil War was the location of a number of minor engagements and for a time of a large colony of African-American escaped former slaves during the American Civil War (1861–1865).  Edisto Island was largely abandoned by planters in November 1861 and in December 1861, escaped slaves began setting up their own refugee camps there.  In January 1862, armed African Americans from the island and Confederate forces clashed and a Confederate raid in reprisal killed a small number of unarmed African Americans.  In February, Union forces were stationed on the island to develop it as a staging area for future campaigns against Charleston, twenty-five miles away, as well as to protect the colony, which would eventually number thousands of African Americans.  As Union forces took control of the island, a number of skirmishes occurred, but Confederates withdrew.  In June, most of the Union troops left the island in a campaign, which culminated in the Battle of Secessionville.  In July, the remaining troops withdrew, and the colony was removed to St. Helena Island.  For the rest of the war, a small number of escaped slaves and plantation owners remained and farmed the island, but it was largely abandoned.  Near the end of the war, the island was again used as a location of colonies of freed slaves.
