Here's an interactive map showing the changing cartel territories in Mexico from late 2008 to early 2011.

December 2006: Mexican President Felipe Calderon takes office, promising to fight back against drug cartels. His first two years in office show strong successes against the cartels, with large drug seizures and the capture of several organizations’ leaders. The government’s chief target is the Gulf cartel, the most powerful in Mexico.


December 2008: A two-year-long campaign by the Calderon government against the Gulf cartel has left it crippled. The cartel’s enforcement arm, Los Zetas, splintered off in spring 2008 and now controls much of what used to be Gulf territory. The government’s success is a double-edged sword, however: The decline of the Gulf cartel has left a large power vacuum, encouraging other organizations — and factions within those organizations — to fight to increase their influence.


December 2009: As the government pressures powerful cartels, the situation in Mexico becomes more volatile and two distinct but interconnected wars begin to emerge: the government’s fight against the cartels, and the cartels’ fights between and among themselves. The geography of cartel influence does not change significantly, though one notable exception to this is the rise of the infamous La Familia Michoacana (LFM), which has captured media attention by marrying drug-trafficking activities to a pseudo-religious ideology.


May 2010: A major rift emerges in the Beltran Leyva Organization (BLO) after the death of leader Arturo “El Jefe de Jefes” Beltran Leyva. Two factions emerge, one under Arturo’s brother, Hector, and the other made up of elements of the BLO’s brutal enforcement wing and run by Edgar “La Barbie” Valdez Villarreal.


December 2010: Tensions between the Gulf cartel and Los Zetas also have boiled over into open war in the country’s east, with the Gulf cartel reaching out to its former rivals in Sinaloa as well as LFM to align under the name “New Federation” and pushing Los Zetas from one of their traditional strongholds, Reynosa, though not out of Nuevo Laredo or Monterrey. In its weakened state, Los Zetas began increasing operations outside the normal scope of drug trafficking, such as kidnapping for ransom, and giving rise to a trend that STRATFOR eventually would dub Mexico’s third war: that of the cartels on the Mexican public. Cartel-related violence in the country reaches new heights, with more than 11,000 deaths on record.


April 2011: Violence continues to rise in all parts of the country. The Sinaloa Federation continues to expand its territory north and east, taking over areas formerly under the influence of the Carrillo Fuentes Organization and the Arellano Felix Organization. With the help of Sinaloa, the Gulf cartel has been able to repel offenses from Los Zetas in Reynosa and Matamoros, though the Zetas are proving resilient. LFM appeared to implode in January, but now a large subset of the former LFM seems to have simply rebranded itself as the “Knights Templar.” Its size and capabilities remain unclear.
