Centralism in the context of List of heads of state of Mexico

The periods of Restoration and Regeneration in Swiss history lasted from 1814 to 1847. "Restoration" is the period of 1814 to 1830, the restoration of the Ancien Régime (federalism), reverting the changes imposed by Napoleon Bonaparte on the centralist Helvetic Republic from 1798 and the partial reversion to the old system with the Act of Mediation of 1803. "Regeneration" is the period of 1830 to 1848, when in the wake of the July Revolution the "restored" Ancien Régime was countered by the liberal movement. In the Protestant cantons, the rural population enforced liberal cantonal constitutions, partly in armed marches on the cities. This resulted in a conservative backlash in the Catholic cantons in the 1830s, raising the conflict to the point of civil war by 1847.

The Head of State of Mexico is the person who controls the executive power in the country. Under the current constitution, this responsibility lies with the President of the United Mexican States, who is head of the supreme executive power of the Mexican Union. Throughout its history, Mexico has had several forms of government. Under the federal constitutions, the title of President was the same as the current one. Under the Seven Laws (centralist), the chief executive was named President of the Republic. In addition, there have been two periods of monarchical rule, during which the executive was controlled by the Emperor of Mexico.

The chronology of the heads of state of Mexico is complicated due to the country's political instability during most of the nineteenth century and early decades of the twentieth century. With few exceptions, most of the Mexican presidents elected during this period did not complete their terms. Until the presidency of Lázaro Cárdenas, each president remained in office an average of fifteen months.
