Step-by-step explanation:
The Nigerian playwright who won the Nobel Prize for Literature in 1986 and whose plays include Death and the King's Horsemen is Wole Soyinka. Wole Soyinka is renowned for his work in drama, poetry, and prose, significantly contributing to the world of literature. His distinct voice and the use of traditional African theater conventions have earned him a place among the world's most respected playwrights. In contrast to Soyinka's powerful social and political critiques, other playwrights like Eugene O'Neill, Tennessee Williams, and the first non-European Nobel laureate Rabindranath Tagore also shaped the landscape of 20th-century theater. Their works grappled with the human condition, each bringing their unique perspectives to the global stage. Additionally, figures like Nigerian philosopher Sophie Olúwolé and British-Nigerian artist Yinka Shonibare emerged from different fields, further enriching the cultural tapestry of Nigeria's intellectual history.
