Felipe Calderón, the President of Mexico, launches a military-led offensive to put down the drug cartel violence in the state of Michoacán. This effort is often regarded as the first event in the Mexican Drug War.

Felipe de Jesús Calderón Hinojosa is a Mexican politician and lawyer who served as the 63rd president of Mexico from 2006 to 2012 and Secretary of Energy during the presidency of Vicente Fox between 2003 and 2004. He was a member of the National Action Party for 30 years before quitting the party in November 2018.

The president of Mexico, officially the president of the United Mexican States, is the head of state and head of government of Mexico. Under the Constitution of Mexico, the president heads the executive branch of the federal government and is the commander in chief of the Mexican Armed Forces. The office, which was first established by the federal Constitution of 1824, is currently held by Claudia Sheinbaum, who was sworn in on October 1, 2024. The office of the president is considered to be revolutionary, in the sense that the powers of office are derived from the Revolutionary Constitution of 1917. Another legacy of the Mexican Revolution is the Constitution's ban on re-election. Mexican presidents are limited to a single six-year term, called a sexenio. No one who has held the post, even on a caretaker basis, is allowed to run or serve again. The constitution and the office of the president closely follow the presidential system of government.

Operation Michoacán was a joint operation by Federal Police and the Mexican military to eliminate drug plantations and to combat drug trafficking. Initiated on December 11, 2006, the operation was supervised by The Secretary of Public Safety, Attorney General of Mexico, Secretary of the Interior, Mexican Navy and Mexican Army.

Michoacán, formally Michoacán de Ocampo, officially the Free and Sovereign State of Michoacán de Ocampo, is one of the 31 states which, together with Mexico City, compose the Federal Entities of Mexico. The state is divided into 113 municipalities and its capital city is Morelia. The city was named after José María Morelos, a native of the city and one of the main heroes of the Mexican War of Independence.
