Answer: lack of organizational structure
Explanation:
The Niagara Movement was founded in 1905 near Niagara Falls by W. E. B. Du Bois and a group of his supporters who wanted a civil-rights organization to help bring social and political change for African Americans. Although this Movement lacked a strong organizational structure and ultimately had little influence on legislative work, its goals were the precedent for the National Association for the Advancement of Colored People (NAACP), founded in 1909.
