Final answer:
Nehanda Nyakasikana was the spiritual link between the First and Second Chimurenga in Zimbabwe, serving as a symbol of resistance. Nationalist literature from the 1950s and 1960s often revolved around decolonization, cultural impacts of colonial rule, and national identity within anti-colonial movements.
Step-by-step explanation:
The spirit medium that became the link between the First and Second Chimurenga, which were the freedom struggles in Zimbabwe against colonial rule, was Nehanda Nyakasikana. She was a Shona spiritual leader who inspired the people to fight against the colonizers in the late 19th century and became a symbol of resistance in the Second Chimurenga in the 1960s and 1970s leading to independence.
Nationalist literature of the 1950s and 1960s, particularly in Africa, focused on themes of decolonization, the impact of colonial rule on Indigenous cultures, and the quest for national identity. Writers used their works to criticize the colonial systems, highlight social injustices, and promote African values and ideologies as part of the broader anti-colonial movements.
