African Americans (or African-Americans, also called black Americans) have historically been the second largest ethnic group in the United States, after European Americans (although they have recently been overtaken by Hispanic Americans). The term "African American" is sometimes restricted to the descendants of slaves forcibly brought to America by the aforementioned Europeans; however, there are also more recent immigrants from Africa—or from the Caribbean, another area where Africans were moved as slaves—who don't identify as American, having lived in nations or territories previously or currently claimed by European colonial interests (such as Great Britain, France, Germany, Portugal, Holland, and Spain).
African slaves in America were generally from west Africa, in an area from the western Sahara area down to the Congo region. A handful came from other areas such as modern day Mozambique but this was not common. They were often bought in coastal areas of Africa, or brought there by other Africans. Despite some recent claims, the vast majority of these Africans were not Muslim, or even Jewish by religion, but had tribal beliefs. Some were baptized not long after arrival in the New World. They certainly had little or no connections with ancient Egypt or Israel as some fringe elements claim (e.g., the Black Hebrew Israelites). Egypt and Israel lay thousands of miles from their homelands across the world's largest hot desert.
Conditions in slave ships were appalling with many dying en route. People from different tribes were jumbled together sometimes with no language in common. Despite this some African words appear to have survived in the USA. Most of the slaves were illiterate, although some evidence suggests a few could read and write Arabic. Others learned to read and write later.
Not all African slaves in North America were in the British colonies. The USA gained a new slave population when it took Florida from Spain and Louisiana from France. Hispanics also have some African ancestry, and some slaves were also transported from the Caribbean to the USA. Some Native American tribes, notably the Cherokee, kept black slaves as well. In the American War of Independence, African Americans fought on both sides, with the British offering freedom to some of their supporters. Many of these African American loyalists would later move to Canada. A significant number of the USA's Founding Fathers owned slaves and appear to have seen no contradiction in this.
For most of the history of the US, African Americans were de jure or de facto, denied most of the liberties granted to other Americans. The American Civil War, Reconstruction, and the Civil Rights movement were all attempts to remedy this; however, it was only the latter movement, which permanently removed discriminatory provisions from the law, that achieved any sort of lasting success.
Despite the name, most African Americans now have some European ancestry (usually on their male lines), with smaller percentages of Native, Asian and Hispanic input. This is confirmed by genetic testing. A lot of this dates from the time of slavery, and was out of wedlock or unrecognized. It is partly to do with the sexual coercion and rape of the slavery period, but also on the other side because genuinely loving mixed race couples were long dissuaded from marriage, sometimes by force. The latter tendency occurred well into living memory.
There are distinct and unique African American traditions in art, music, literature, politics, religion and social culture, but the boundaries of these are hazy. Some of these such as jazz, blues etc. have been taken up by other sections of society, and American popular music in general has been heavily influenced by black culture for well over a century.
 Distinct nation
There are those who see African Americans as a distinct nation within the United States, and many African American leaders once fought to have a distinct state. (The republic of Liberia was originally set up for this, but abandoned when it was found that most African Americans did not want to live in Africa.) However, in the modern political climate, this is a fringe opinion, adhered to only by such groups as Louis Farrakhan's Nation of Islam.
Ironically, African Americans' commonalities in culture, history and speech — which are often invoked in this regard, are partly the result of slavery, segregation and racism. It should also be remembered that a great deal of African American idiosyncrasies do not come from Africa (or even Europe), but are a positive reflection of the creativity, innovation, versatility and resourcefulness of African Americans since their arrival in America.
Barack Obama, the 44th President of the United States, is African American, although he is not descended from slaves, but directly from a Kenyan father and still has close relatives in Africa. Unlike the majority of African Americans, he is of East African descent. There are suspicions that other presidents, notably Lincoln and Jefferson, were of African American lineage.
 Embarrassing side effects
As the term "African American" has gained popularity, an interesting side effect has been observed among Americentric white people: They tend to call all black people "African Americans."
For example, on 22 September 2010, a third young man came forward to accuse homophobic megachurch pastor Eddie Long of soliciting gay sex. ABC Radio Network News reported that Long "has one of the largest African American congregations in the world," thus implying that there are many predominantly African American congregations outside of America.
Also, Mavis Leno, wife of Jay Leno (of "Jaywalking" fame, ironically) once appeared on his show to discuss the treatment of "African Americans" in South Africa.
Another effect is the reflection of the first: thinking that all Africans are black. Much of northern Africa, for example, is populated by those of Arabic and Egyptian descent. South Africa, on the other hand, contains a comparatively-large Caucasian populace descendant from British and Dutch colonists, as well as a significant Indian population. Madagascar is largely a mix of African and Malay peoples.
