Mexico is governed from an old lake basin

Mexico is a federation whose capital stands on a lake bed. Mexico City lies in the Valley of Mexico, where Lake Texcoco was, and the powers of the Union sit in that basin. The country itself runs from the Pacific to the Gulf and the Caribbean. In the north it shares a long border with the United States. The basin governs. The map is larger than the basin.

Tenochtitlan stood on islands in the lake. The later city drained the water and stayed in the basin. The basin is closed. What comes off the mountains does not run by itself to the sea. To govern from this hollow is different from governing from a harbour or a river. The republic has to hold a dry north, a volcanic centre and a tropical south as one federation, from a city whose ground is still that of a lake.

A basin as the political centre

The constitution makes Mexico City the capital and the seat of the powers of the Union, and it makes the city a federal entity of its own. It is not a province that happened to grow large. The valley around it is a closed basin. Rain and wastewater have no easy way out. The old lake is not only a plaque: remnants of the water and the soft lake bed are the physical situation of the city. The ground yields because it is the sediment of a lake. Politics sits on that ground.

The political weight of the basin is older than the present constitutional text. The Mexica city stood here, then the colonial capital, then the federal seat. Outside the basin the country changes quickly: volcanoes and highland, then the dry plateau to the north, lowland toward the Gulf and the south. A ministry on the Zócalo writes rules for coasts it cannot see from that square. That distance is the ordinary task of the federation.

Pacific, Gulf, and the northern border

The Pacific lies to the west, the Gulf of Mexico to the east, the Caribbean on the Yucatán. Baja California is a long peninsula on the Pacific. In the north the land border runs with the United States, in the south with Guatemala and Belize. The federation is the land between those edges. The northern border organises trade, migration and security in a way no southern border repeats. The capital in the basin has to write rules whose effects arrive at once on a desert frontier and on a tropical river.

On 1,964,375 square kilometres live 131,946,900 people. The Mexican peso, issued by the Banco de México, is the currency. The scale is the point: this is not an island state and not a city-state. It is a federation large enough that the lake basin can be the political centre without being the typical landscape. Desert in the north, volcano in the centre, tropics in the south remain one state because the constitution treats them as one federation and leaves the capital in the basin.

The republic is governed from a basin that was once a lake.

Spanish in the union, other languages in the text

Spanish carries federal life, the statute and the capital. The constitution does not stop there. In the article on indigenous peoples it gives indigenous languages the same validity as Spanish in the territory where they are spoken. Nahuatl, Maya, Mixtec, Zapotec and other languages are not a decoration around a monolingual state. The text refuses that picture, even while Mexico City works in Spanish. The basin speaks the language of the federation. The country speaks more.

Recognition does not by itself make every office bilingual. It sets a constitutional sentence: the federation may not treat indigenous languages as private custom. Where they are spoken, they have the same validity as Spanish. That is the linguistic form of a country governed from one basin and lived in many regions. The peso is national. The language of the basin is not the only one.

Mexico is readable outward from the lake bed. The capital is a federal entity in a basin that was once water. The map reaches two seas and a northern border. The constitution lets Spanish carry the union and names other languages as valid where they are spoken.
