The club came up with the name of Sociedade Esportiva São Borja, being derived from the fusion of International and Cruzeiro, two traditional teams vied in the city and went through financial difficulties.

The merger aimed to unite the population to support and strengthen football in São Borja, and started using the stadium Vicente Goulart.

In the 1981 Campeonato Brasileiro Série C, the São Borja reached the 3rd stage of the competition, finishing the race in 5th place.

After this tournament the club graduated from professional football for 15 years, returning in 2012 with the name of Associação Esportiva São Borja and disputing the Campeonato Gaúcho Série A2, which finished in 11th place.
