Portuguese Guinea (also Guinea or the Overseas Province of Guinea) was the name for what is today Guinea-Bissau from 1446 to September 10, 1974.

Though the Kingdom of Portugal had claimed the area four years earlier, Portuguese explorer Nuno Tristão sailed around the coast of West Africa, reaching the Guinea area in about 1450, searching for the source of gold and other valuable commodities that had slowly been trickling up into Europe via land routes for the preceding half century. Sometime later, slaves were also added to the list. Portuguese Guinea had been part of the Sahel Empire, and the local Landurna and Naula tribes traded in salt and grew rice. Like in many other regions across Africa, powerful indigenous kingdoms along the Bight of Benin relied heavily on a long established slave trade. The Ashanti exploited their military predominance to bring slaves to coastal forts established first by Portugal after 1480, and then soon afterwards by the Dutch, Danish, and English. The slaving network quickly expanded deep into the Sahel, where the Mossi diverted an ancient slaving trade away from the Mediterranean towards the Gold Coast. With the help of local tribes in about 1600, the Portuguese, and numerous other European powers, including France, Britain and Sweden, set up a thriving slave trade along the West African coast. However, the local black African rulers in Guinea, who prospered greatly from the slave trade, had no interest in allowing the white Europeans any further inland than the fortified coastal settlements where the trading took place. The Portuguese presence in Guinea was therefore largely limited to the port of Bissau and Cacheu. For a brief period in the 1790s the British attempt to establish a rival foothold on an offshore island, at Bolama. But by the 19th century the Portuguese were sufficiently secure in Bissau to regard the neighbouring coastline as their own special territory, also in part of present southern Senegal.

Guinea ⁱ/ˈɡɪni/, officially the Republic of Guinea (French: République de Guinée), is a country in West Africa. Formerly known as French Guinea (Guinée française), it is today sometimes called Guinea-Conakry to distinguish it from its neighbour Guinea-Bissau and the Republic of Equatorial Guinea. Guinea has almost 246,000 square kilometres (94,981 sq mi) and a population of 10,057,975. It forms a crescent by curving from its western border on the Atlantic Ocean toward the east and the south. Its northern border is shared with Guinea-Bissau, Senegal, and Mali, the southern one with Sierra Leone, Liberia, and Côte d'Ivoire. The Niger River's source is in the Guinea Highlands in southeastern Guinea.

Guinea is geographically divided into eight administrative regions and subdivided into thirty-three prefectures. Conakry is the capital, largest city and economic centre. The other major cities in the country include Kankan, Nzérékoré, Kindia, Labe, Guéckédou, Mamou and Boke.

Guinea's 10 million people belong to twenty-four ethnic groups. The largest and most prominent groups are the Fula 40%, Mandingo 30%, and Susu 20%.

African Americans (also referred to as Black Americans or Afro-Americans, and formerly as American Negroes) are citizens or residents of the United States that have ancestry from any of the native populations of Sub-Saharan Africa.

African Americans make up the single largest racial minority in the United States. Most African Americans are of West and Central African descent and are descendants of enslaved Africans within the boundaries of the present United States. However, some immigrants from African, Caribbean, Central American or South American nations, or their descendants, may be identified or self-identify with the term.

African-American history starts in the 16th century with African slaves who quickly rose up against the Spanish explorer Lucas Vázquez de Ayllón and progresses to the present day, with Barack Obama as the 44th and current President of the United States. Between those landmarks there have been events and issues, both resolved and ongoing, including slavery, racism, Reconstruction, development of the African-American community, participation in the great military conflicts of the United States, racial segregation, and the Civil Rights Movement.

Wilhelm Richard Wagner ( /ˈvɑːɡnər/; German pronunciation: [ˈʁiçaʁt ˈvaːɡnɐ]; 22 May 1813 – 13 February 1883) was a German composer, conductor, theatre director and polemicist primarily known for his operas (or "music dramas", as he later called them). Wagner's compositions, particularly those of his later period, are notable for their complex texture, rich harmonies and orchestration, and the elaborate use of leitmotifs: musical themes associated with individual characters, places, ideas or plot elements. Unlike most other opera composers, Wagner wrote both the music and libretto for every one of his stage works. Perhaps the two best-known extracts from his works are the Ride of the Valkyries from the opera Die Walküre, and the Wedding March (Bridal Chorus) from the opera Lohengrin.

Initially establishing his reputation as a composer of works such as The Flying Dutchman and Tannhäuser which were broadly in the romantic vein of Weber and Meyerbeer, Wagner transformed operatic thought through his concept of the Gesamtkunstwerk ("total work of art"). This would achieve the synthesis of all the poetic, visual, musical and dramatic arts and was announced in a series of essays between 1849 and 1852. Wagner realized this concept most fully in the first half of the monumental four-opera cycle Der Ring des Nibelungen. However, his thoughts on the relative importance of music and drama were to change again, and he reintroduced some traditional operatic forms into his last few stage works, including Die Meistersinger von Nürnberg.
