States


Roles and powers of the states

The states of the Mexican Federation are free, sovereign, autonomous and independent of each other. They are free to govern themselves according to their own laws; each state has a constitution that cannot contradict the federal constitution, which covers issues of national competence. The states cannot make alliances with other states or any independent nation without the consent of the whole federation, except those related to defense and security arrangements necessary to keep the border states secure in the event of an invasion. The political organization of each state is based on a separation of powers in a congressional system: legislative power is vested in a unicameral congress (the federal congress has two chambers), executive power is independent of the legislature and vested in a governor elected by
universal suffrage Universal suffrage (also called universal franchise, general suffrage, and common suffrage of the common man) gives the right to vote to all adult citizens, regardless of wealth, income, gender, social status, race, ethnicity, or political sta ...

Internal organization of states

The states are internally divided into municipalities. Each municipality is autonomous in its ability to elect its own council. A council is headed by a mayor who is elected every three years. Each municipality has a council composed of councilors in terms of population size. In most cases, the council is responsible for providing all utilities required for its population. This concept, which arises from the

However, the Federal District received more autonomy in 1997, and its citizens were then able to elect their chief of government for the first time. In 2016, the Mexican Congress approved a constitutional reform eliminating the federal district and establishing Mexico City as a fully autonomous entity on par with the states. However, unlike the other states of the Union, it would receive funds for education and health. When full autonomy was granted, Mexico City adopted its own constitution (it previously had only an organic law, the Statute of Autonomy) and its boroughs expanded their local government powers.

According to the General Law of Linguistic Rights of the Indigenous Peoples, the nation recognizes 68 indigenous languages as " national languages", with the same validity as Spanish in the territories in which they are spoken. The indigenous peoples are entitled to request public services in their languages.

as emperor. On July 21, 1822, Iturbide was crowned Emperor of Mexico. However, the ''Constitutional Empire'' quickly demonstrated the incompatibility of its two main parts: the Emperor and the Constituent Congress. The deputies were imprisoned just for expressing their opinions, and eventually Iturbide decided to dissolve the Congress and instead establish a National Board. The lack of a legitimate legislature, the illegitimacy of the Emperor, and the absence of real solutions to the nation's problems increased revolutionary activity.

Iturbide was forced to reestablish the Congress and, in a vain attempt to save the order and keep the situation favorable to his supporters, he abdicated the crown of the empire on March 19, 1823. Congress nullified the designation of Iturbide and therefore the recognition of the abdication. It deemed the coronation of Iturbide to have been a logical mistake in consummation of Independence. The dissolution of the Empire was the first political realignment of independent Mexico.


Federal republic

After the fall of the Empire, a triumvirate called the Supreme Executive Power was created. The provisional government created the

Its sixth article stated, "The component parts of the Republic are free, sovereign and independent States in that which touches internal administration and government".

. On January 31, 1824, the decree to create a Constitutive Act of the Mexican Federation was issued, which incorporated the basic structure of the Federal Republic. It was determined that the criteria for inviting states to the federation should be that they "...not be so few that through expansion and wealth in a few years they be able to aspire to constitute themselves as independent nations, breaking the federal bond, nor so many that through lack of manpower and resources the system should come to be unworkable." Between 1823 and 1824, some of the ''Free States'' created their own constitutions, and others had already installed a Constituent Congress. Special cases were those of Yucatán, which on December 23, 1823, decided to join the federation but as a Federated Republic, and
