The Argentine Division 2, also known as Primera B Nacional, is the second-tier football league in Argentina. It was established in 1986 and has since played a crucial role in developing young talents for the top-flight division. The competition consists of 32 teams divided into two zones, with each team playing a total of 30 matches. Notable clubs that have enjoyed success in this league include Quilmes, Chacarita Juniors, and Ferro Carril Oeste. Interestingly, the league has seen several teams achieve promotion to the top division only to be relegated back down in the following season.
