Question: Cyril Briggs was dedicated to advancing what  worldwide intellectual movement that aims to encourage and strengthen bonds of solidarity between all people of African descent

full_context: Document 1: African-American self-determination: 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.
Document 2: The Revolutionary Black Panther Party: The Revolutionary Black Panther Party or RBPP (coined the continuity of the Black Panther Party, BPP) is a revolutionary black nationalist, Pan-African and socialist (Neo-Afrikan Socialist) group who is a defined as a “Black military” (militia). The Revolutionary Black Panther Party, claims continuity of the Black Panther Party of the 1960s, their leader Dr. Alli Muhammad MS, PhD, MD (title, Chief-General-In-Command/Commander), was raised a Black Panther in the Black Panther Party of the 1960s-1980s which was dissolved in 1982. In 1992 the RBPP was officially named and has been carrying on the Black Panther legacy in its view ever since.
Document 3: Black separatism: Black separatism is a separatist political movement that seeks separate economic and cultural development for those of African descent in societies, particularly in the United States. Black separatism is a subcategory of black nationalism, stemming from the idea of racial solidarity, and implies that blacks should organize themselves on the basis of their common experience of oppression as a result of their blackness, culture, and African heritage. Black separatism in its purest form, as a subcategory of black nationalism, asserts that blacks and whites ideally should form two independent nations. Black separatists also often seek their original cultural homeland. Black separatists generally think that black people are hindered in their advancement in a society dominated by a white majority.
Document 4: Eldridge Cleaver: Leroy Eldridge Cleaver (August 31, 1935 – May 1, 1998) was an American writer and political activist who became an early leader of the Black Panther Party. His 1968 book, "Soul On Ice", is a collection of essays that, at the time of its publication, was praised by "The New York Times Book Review" as "brilliant and revealing". In the most controversial part of the book, Cleaver acknowledges committing many acts of rape.
Document 5: Harry Haywood: Harry Haywood (February 6, 1898 – January 4, 1985) was a leading figure in both the Communist Party of the United States (CPUSA) and the Communist Party of the Soviet Union (CPSU). His goal was to connect the political philosophy of the Communist Party with the issues of race. In 1926, he joined other African-American Communists and travelled to the Soviet Union to study the effect of Communism on racial issues found in the United States. His work there resulted in his selection to be the head of the Communist Party's Negro Department. The party platform changed by the late 1930s and began to stray away from advocating for African-American self-determination. As the party's platform changed over time, Haywood lost his stance within the party. His work also included creating a group to help the Scottsboro boys case. Haywood was also an author. His first book was "Negro Liberation", published in 1948. After he was expelled from his affiliating party, he wrote an autobiography called "Black Bolshevik", which was also published in 1978. He contributed major theory to Marxist thinking on the national question of African Americans in the United States. He was also a founder of the Maoist New Communist movement.
Document 6: Black existentialism: Black existentialism or Africana critical theory is a school of thought that "critiques domination and affirms the empowerment of Black people in the world". Although it shares a word with existentialism and that philosophy's concerns with existence and meaning in life, it "is predicated on the liberation of all black people in the world from oppression". It may also be seen as method, which allows one to read works by African-American writers such as W. E. B. Du Bois, James Baldwin, and Ralph Ellison in an existentialist frame. Lewis Gordon argues that black existentialism is not only existential philosophy produced by black philosophers but is also thought that addresses the intersection of problems of existence in black contexts.
Document 7: Congress of Afrikan People: The Congress of Afrikan people (CAP) was a proponent of black nationalism. Active in the 1970s, CAP's ideology was set around Maoist theory and practice. Its activities illustrate fluidity and changing nature of black radicalism in this period. It later became the Revolutionary Communist League (Marxist-Leninist-Mao Tse-tung Thought), led by Amiri Baraka, which merged into the League of Revolutionary Struggle (Marxist-Leninist). When this group split, some of the members went into Freedom Road Socialist Organization.
Document 8: African Renaissance: The African Renaissance is the concept that African people and nations shall overcome the current challenges confronting the continent and achieve cultural, scientific, and economic renewal. The African Renaissance concept was first articulated by Cheikh Anta Diop in a series of essays beginning in 1946, which are collected in his book "Towards the African Renaissance: Essays in Culture and Development, 1946-1960". This concept has been further popularized by former South African President Thabo Mbeki during his term of office, heralding the beginning of The African Renaissance, and it continues to be a key part of the post-apartheid intellectual agenda. It has found new expression and momentum within the International Decade for People of African Descent through the Door of Return initiative which is coming out of the historical Maroon community of Accompong Jamaica in cooperation with Nigeria, Ghana and Zimbabwe. The revival is being lead by Accompong Finance Minister Timothy E. McPherson Jr. and Nigeria's Senior Special Assistant to the President on Diaspora and Foreign Affairs, Hon. Abike Dabiri.
Document 9: Black orientalism: Black orientalism is an intellectual and cultural movement found primarily within African-American circles. While similar to the general movement of Orientalism in its negative outlook upon Western Asian - especially Arab - culture and religion, it differs in both its emphasis upon the role of the Arab slave trade and the Coolie slave trade in the historic dialogue between sub-Saharan Africa and the Arab - and greater Muslim - world, as well as a lack of colonial promotion over the Middle East region as was promoted by European orientalism in the same region. The term "black orientalism" was first used by Kenyan academic Ali Mazrui in his critique of Henry Louis Gates, Jr.'s documentary "Wonders of the African World". Supporters of this movement include writers such as Chinweizu.
Document 10: The Cricket: Black Music in Evolution: The Cricket, subtitled "Black Music in Evolution", was a magazine created in 1968 by Amiri Baraka (then LeRoi Jones), Larry Neal and A. B. Spellman. Baraka has said: "Larry Neal, AB and I realized the historical influence of music on African /Afro American Culture. I saw the magazine as a necessary dispenser of this influence as part of a continuum. And that attention to the culture was a way of drawing attention to the people’s needs and struggle." The headquarters was in New York City.
Document 11: African Blood Brotherhood: The African Blood Brotherhood for African Liberation and Redemption (ABB) was a radical U.S. black liberation organization established in 1919 in New York City by journalist Cyril Briggs. The group was established as a propaganda organization built on the model of the secret society. The group's socialist orientation caught the attention of the fledgling American communist movement and soon evolved into a propaganda arm of the Communist Party of America. The group was terminated in the early 1920s.
Document 12: Back-to-Africa movement: 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.
Document 13: Cyril Briggs: Cyril Valentine Briggs (May 28, 1888, Nevis – October 18, 1966, Los Angeles, California) was an African-Caribbean American writer and communist political activist. Briggs is best remembered as founder and editor of "The Crusader," a seminal New York magazine of the New Negro Movement of the 1920s and as founder of the African Blood Brotherhood, a small but historically important radical organization dedicated to advancing the cause of Pan-Africanism.
Document 14: Pan-Africanism: Pan-Africanism is a worldwide intellectual movement that aims to encourage and strengthen bonds of solidarity between all people of African descent. Based upon a common fate going back to the Atlantic slave trade, the movement extends beyond continental Africans, with a substantial support base among the African diaspora in the Caribbean, Latin America and the United States. It is based on the belief that unity is vital to economic, social, and political progress and aims to "unify and uplift" people of African descent. The ideology asserts that the fate of all African peoples and countries are intertwined. At its core Pan-Africanism is "a belief that African peoples, both on the continent and in the diaspora, share not merely a common history, but a common destiny".
Document 15: L'Étudiant noir: L'Étudiant noir, Journal Mensuel de l’Association des Étudiants Martiniquais en France (translated roughly as "The Black Student: Monthly Journal of the Martinican Student Association in France") is a journal created by Aimé Césaire in 1935 in Paris. It contains the first poems written by Léon Damas and some of Leopold Sedar Senghor's first articles, both of whom were student association members at the time. Only two issues of the journal were ever published, March 1935 and May–June 1935. The most notable article was written by Aimé Césaire, titled "Conscience raciale et révolution sociale" ("Racial Consciousness and social revolution") in the May–June 1935 issue, which was the first work to explore the concept of négritude.
