In which prison was UBN formed?

The formation of the United Blood Nation (UBN) is historically tied to Rikers Island Prison in New York. Established in the 1990s, UBN was created by inmates who aimed to protect themselves and assert control within the prison environment. The crew emerged as a response to the violent dynamics present on Rikers, where rival gangs posed significant threats to the safety of inmates.

Rikers Island, being a notorious facility with a high inmate population, became a breeding ground for gang activities, making it the ideal location for the establishment of UBN. The group's influence expanded beyond the prison walls and into the streets of New York City, reinforcing its significance in the urban gang landscape.

In contrast, while the other prison options—San Quentin, Leavenworth, and Alcatraz—are well-known penal facilities, they are not historically linked to the formation of UBN. Each of these institutions has its own distinct history and context, but none signify the origins of the United Blood Nation like Rikers Island does. Thus, identifying Rikers Island as the birthplace of UBN reflects the accurate historical context and the foundational narratives surrounding the gang's emergence.
