United Blood Nation, simply known as U.B.N is a prison gang formed in 1978 within the California prison system in San Quentin State Prison, California. The gang was formed to unite Bloods within the California prison system, to be protected against rival Crips and MS-13.
Members of this gang are known for burning three circles in a triangular shape on their upper right arm or right hand to show affiliation to it. Some members would tattoo a bulldog's face on their right hand, letters M.O.B to identify themselves from outsiders also.
In 2012, the gang was estimated to have approximately 15,000 members across the United States.
