The politics of Mexico function within a framework of a federal presidential representative democratic republic whose government is based on a multi-party congressional system, where the President of Mexico is both head of state and head of government. The federal government represents the United Mexican States and is divided into three branches: executive, legislative and judicial, as established by the Political Constitution of the United Mexican States, published in 1917. The constituent states of the federation must also have a republican form of government based on a congressional system as established by their respective constitutions.

This sparked a movement away from the PRI's authoritarian rule.

The Mexican Communist Party was a communist party in Mexico. It was founded in 1917 as the Socialist Workers' Party by Manabendra Nath Roy, a left-wing Indian revolutionary. The PSO changed its name to the Mexican Communist Party in November 1919. It was outlawed in 1925 and remained illegal until 1935, during the presidency of the leftist Lázaro Cárdenas. The PCM saw in the left wing of the nationalist regime that emerged from the Mexican Revolution a progressive force to be supported—i.e. Cárdenas and his allies. In the end, the PCM disappeared after helping form the Party of the Democratic Revolution, a split from the PRI led by the son of Lázaro Cárdenas, Cuauhtémoc Cárdenas.

It existed between 1987 and 1989.

In the context of Mexican politics, a national political association is a citizens' association intended to assist in the development of democratic life and the country's political culture, as well as being intended to create a better informed public opinion. They are similar to political parties; they used to receive public funding through the Federal Electoral Institute (IFE) for the promotion of their activities and ideas, but this was no longer the case after the 2008 political reform; after the 2014 political reform and the transformation of the IFE into INE, only political parties and independent candidates can receive public funding. APNs are not allowed to register candidates for election, though they can publicly support those of other political parties through association agreements and may only do so during federal elections. The creation of an APN is regarded as the first step towards the creation of a full-fledged political party.
