Which synonym of unique best replaces it in the passage below (paragraph 8)?

Another method of self-expression and racial pride seen in the anthology was an interest in “cultural pluralism,” which encouraged an interest in African roots while developing a unique African American culture. Locke, in particular, encouraged African Americans to reclaim their African identity and, therefore, a cultural heritage. He was interested in African influences on Caribbean nations and on African Americans and encouraged younger artists to study African culture. In his anthology, he included an essay by W. E. B. Du Bois on the relationship between the “New Negro” movement and events in Africa, including colonialism and struggles for freedom that he believes paralleled the African American plight. Locke chose not to mention Marcus Garvey or his movement, which encouraged African Americans to move to Africa, considering him too controversial a figure and not representative of the “New Negro” he desired to promote.
