Blood Oath Gangland : Season 1 Episode 12

During the late 1990's, the New York Metropolitan area was plagued by the random violence of a new breed of street gang: The United Blood Nation. Created in 1993 by Rikers Island inmate, Omar Portee, the UBN emulated the Bloods street gang on the West Coast, but was more randomly violent. Portee formed the UBN in an effort to unite the African-American prisoners against Hispanic gangs like the Latin Kings. Better known as "OG Mack," Portee led the UBN from behind prison walls, and eventually on the streets of New York. By the mid 1990's, like an epidemic, the Bloods had taken over the tri-state area, which had historically belonged to the Latin Kings. By the year 2000, the Bloods were the most violent gang on the East Coast- and OG-Mack became known as the Godfather of the East Coast Bloods.
