Answer :
Both were black nationalist groups but the difference is that the Black Panther Party (BPP) were a more right-winged extremist group compared to the National Urban League (NUL) when it came to the two political/social activist parties. Basically the BPP were willing to break the law to achieve their demands, while the NUL did it via the system with more progressive tactics. Or, less violent at the least.
The correct answer is "community self-defense v. economic self-reliance".
The Black Panther Party was a political organization founded in October 1996. It implemented a common practice of constituting "armed" citizens patrol to monitor the activities of police officers while they were on duty in order to prevent acts of use of excessive force against African Americans. They instituted various social programs which offered direct aid to the African American American Communities.
On the other hand, the National Urban League was a nonpartisan civil rights organization founded in 1910 that sought equality of rights among all citizens in the United States. They eventually achieved many improvements towards this objective through their actions in courts.
