Although the Bac fight was rooted in the traditions of the Ebro Lands and, until the first half of the 20th century, it was a general practice, even forming part of the usual repertoire of children's games throughout the territory, the lack of an organization and regulations made the practice decline until its near disappearance, remaining only maintained by a small number of people. One of them, MR. Juan Jose Valldeperez Casanova (knowledgeable and conservative of Bac, as well as a teacher of karate, jujitsu and Greco-Roman wrestling) included Bac in the training program of the karate clubs in which he taught. In this way, he got the Bac fight to be practiced again within the scope of the kushinkai karate clubs of Camarles, Deltebre and San Jaume d'Enveja. And later he was joined by the Kushinkai club in Sant Carles de la Ràpita.
These clubs regularly organize Bac exhibitions within the framework of the traditional rice festivals that are held annually in the delta area and also on the occasion of the local festivals of the municipalities. Likewise, these clubs have been organizing Bac children's competitions periodically from 2010 to the present.
In 2015, these sports clubs began the procedures for the Bac to be registered in the list of recognized physical-sports leisure activities and registered in the Registry of Sports Entities. On October 6, 2016, the Catalan Sports Council approved the inclusion of Bac in the registry. From there, the procedures for the creation of the Associació de Lluita del Bac de les Terres de l’Ebre (in Catalan) could be started. These procedures were delayed due to the pandemic, but the association made up of the aforementioned karate clubs has recently been established.
