In short: Meaning hot waters, this central Mexican state is a powerhouse of automotive manufacturing and economic growth. Despite being one of the smallest states by land and population, it consistently ranks among the most competitive regions in the country, blending colonial history with a modern, high-speed industrial identity.

Aguascalientes, located in the north-central Bajío region, is a territory defined by its strategic geography and resilience. With a population of 1,425,607 as of the 2020 census, it is the 27th most populous state in Mexico. Its history is deeply rooted in the colonial era, beginning with Spanish efforts to secure the Camino de la Plata—a vital silver transport route—against the Chichimeca people. The town of Aguas Calientes was formally established on October 22, 1575, by Juan de Montoro, following orders from King Felipe II to ensure safe passage for silver convoys.

The state's path to autonomy was complex and fraught with conflict. For decades, it was a dependency of Zacatecas, with various attempts at separation thwarted by shifting national politics and legal requirements. It was not until the Constitution of 1857 that Aguascalientes was formally recognized as a sovereign state, a status finalized on October 27, 1857. Local folklore suggests the state's distinct shape resembles a kiss, allegedly promised by a governor's wife to the president in exchange for the territory's independence from Zacatecas.

Today, the state has transformed into an industrial titan. It is a critical hub for the automotive sector, hosting two Nissan plants that produce over half a million vehicles annually. This economic dynamism, supported by projects like the Financial District Río San Pedro and a robust foreign direct investment rate, has placed it as the third most competitive state in Mexico. Beyond industry, it is famous for the Feria Nacional de San Marcos, the largest fair in the country, and its capital city, which is celebrated for its cleanliness, safety, and colonial architecture.
