Final answer:
Garveyism and Pan-Africanism, championed by Marcus Garvey, were crucial in advocating for black independence and unity. They had significant visible results in the United States, aiding the progression of Black nationalism, and in Africa, where they inspired independence movements.
Step-by-step explanation:
The importance of Garveyism, as articulated by Marcus Garvey, and Pan-Africanism lies in their roles as re-membering visions and practices to reconnect people of African descent to their collective economic, political, and social heritage. Garveyism promoted the idea of black independence and self-reliance through the creation of the Universal Negro Improvement Association (UNIA). The UNIA aimed to enhance the standing of black individuals by fostering black pride, economic independence, and a universal African nationhood. Garvey's newspaper The Negro World spread these ideas globally, urging an end to colonialism and for blacks to 'go back to Africa,' all while fostering economic empowerment through businesses owned and operated by blacks.
The most visible results of these movements were seen in the US where they fueled the growth of Black nationalism and influenced later movements such as the Civil Rights Movement and the Black Power Movement. African nations also drew inspiration from Garveyism and Pan-Africanism, leading to anti-colonial fervor and the push for independence across the continent.
