Gulf Cartel
In early 2010 the Zetas made public their split from the Gulf Cartel and began a bloody war with the Gulf Cartel over control of northeast Mexico's drug trade routes. This war has resulted in the deaths of thousands of cartel members and suspected members. Furthermore, due to alliance structures, the Gulf Cartel-Los Zetas conflict drew in other cartels, namely the Sinaloa Cartel which fought the Zetas in 2010 and 2011.
