Question: What were additional names for the Back-to-Africa movement pioneered by Alfred Charles Sam?
Context: Benjamin "Pap" Singleton (1809–1892) was an American activist and businessman best known for his role in establishing African American settlements in Kansas.  A former slave from Tennessee who escaped to freedom in 1846, he became a noted abolitionist, community leader, and spokesman for African-American civil rights.  He returned to Tennessee during the Union occupation in 1862, but soon concluded that blacks would never achieve economic equality in the white-dominated South.  After the end of Reconstruction, Singleton organized the movement of thousands of black colonists, known as Exodusters, to found settlements in Kansas.  A prominent voice for early black nationalism, he became involved in promoting and coordinating black-owned businesses in Kansas and developed an interest in the Back-to-Africa movement. Walker and Williams In Dahomey (1903-1905) is a black musical written by Jesse A. Shipp as a satire on the American Colonization Society's back-to-Africa movement.  Regarded as "the first full-length musical written and played by blacks to be performed at a major Broadway house”, In Dahomey is lauded as a marquee turning point for African American representation in vaudeville theater.  It featured lyrics by poet Paul Laurence Dunbar, music by popular ragtime musician Will Marion Cook, and was produced by Harry Seamon and McVon Hurtig.  The musical starred leading comedians George Walker and Bert Williams, two iconic figures of vaudeville entertainment at the time.  In Dahomey opened in the New York Theater on February 18, 1903.  The musical ran for 53 completed performances, including two tours in the United States and one tour of the United Kingdom.  In total, "In Dahomey" ran for a combined total of four years. Alfred Charles Sam (c.1880 – 1930s?) , known as Chief Alfred Sam, was a Gold Coast-born merchant and pioneer pan-Africanist who in 1913-15 encouraged the resettlement of African Americans as part of the Back-to-Africa movement. Reformational philosophy is a Neo-Calvinistic movement pioneered by Herman Dooyeweerd and D. H. Th.  Vollenhoven that seeks to develop philosophical thought in a radically Protestant Christian direction. Mortimo St George "Kumi" Planno, (6 September 1929, Cuba – 5 March 2006, Kingston, Jamaica) was a renowned Rastafari elder, drummer, and considered one of the ideological founders of the back-to-Africa movement founded in the 1910s by Marcus Garvey.  He is best known as the Rasta teacher and friend of Bob Marley, and as the man who commanded the respect of a chaotic crowd during the arrival of Emperor Haile Selassie on his visit to Jamaica in 1966.  He is referred to by other Rastas as a teacher and a leader within the context of the faith, given his life's work. The Back-to-Africa movement, also known as the Colonization movement or Black Zionism, originated in the United States in the 19th century.  It encouraged those of African descent to return to the African homelands of their ancestors.  This movement would eventually inspire other movements ranging from the Nation of Islam to the Rastafari movement, and proved to be popular among African-Americans. Prince Hall (  17351738 1807) was an African American noted as an abolitionist for his leadership in the free black community in Boston and as the founder of Prince Hall Freemasonry.  He lobbied for education rights for black children and was active in the back-to-Africa movement. The Black Star of Africa is a black five-pointed star (★) symbolizing Africa in general and Ghana in particular.  The Black Star Line, founded in 1919 by Marcus Garvey as part of the Back-to-Africa movement, modelled its name on that of the White Star Line, changing the colour from white to black to symbolise ownership by black people rather than white people.  The black star became a symbol of Pan-Africanism and anti-colonialism.  Described as the "Lodestar of African Freedom", the black star was used in 1957 by Theodosia Okoh in the design of the Flag of Ghana. African-American self-determination refers to efforts to secure self-determination for African-Americans and related peoples in North America.  It often intersects with the historic Back-to-Africa movement and general Black separatism, but also manifests in present and historic demands for self-determination on North American soil, ranging from autonomy to independence.  Reparations for slavery and other oppressions are often a key demand for advocates of African-American self-determination. The Black Star Line (1919−1922) was a shipping line incorporated by Marcus Garvey, the organizer of the Universal Negro Improvement Association (UNIA), and other members of the UNIA.  The shipping line was created to facilitate the transportation of goods and eventually African Americans throughout the African global economy.  It derived its name from the White Star Line, a line whose success Garvey felt he could duplicate.  Black Star Line became a key part of Garvey's contribution to the Back-to-Africa movement.  It was one among many businesses which the UNIA originated, such as the Universal Printing House, Negro Factories Corporation, and the widely distributed and highly successful "Negro World" weekly newspaper.
