Map - Pachuca (Pachuca de Soto)

Pachuca, formally known as Pachuca de Soto, is the capital and largest city of the Mexican state of Hidalgo. It is located in the south-central part of the state. Pachuca de Soto is also the name of the municipality of which the city serves as municipal seat. Pachuca is located about 90 km from Mexico City via Mexican Federal Highway 85. There is no consensus about the origin of the name Pachuca. It has been traced to the word pachoa (strait; opening), Pachoacan (place of government; place of silver and gold), and patlachuican (place of factories; place of tears).

The official name of Pachuca is Pachuca de Soto in honor of congressman Manuel Fernando Soto, who is given credit for the creation of Hidalgo state. Its nickname of "La bella airosa" (Beautiful Airy City) comes from the strong winds that blow into the valley through the canyons to the north of the city. In the indigenous Otomi language, Pachuca is known as Nju̱nthe. The area had been long inhabited, but except for some green obsidian the mining that Pachuca is famous for began in the mid-16th century, during Spanish colonial rule.

Pachuca remained a major mining center until the mid-20th century, with the city's fortunes going up and down with the health of the mining sector. In the mid-20th century, a major downturn in mining pushed Pachuca to change the basis of its economy to industry, resulting in the revamping of the Universidad Autónoma de Hidalgo. Today mining forms only a fraction of the municipality's economy. One cultural aspect that makes Pachuca stand out is the influence of the Cornish miners who immigrated here in the 19th century. Many of their descendants remain in Pachuca and nearby Real del Monte, as well as two heritages that define the city, football and a dish called "pastes."

Evidence of early human habitation in this area is found in Cerro de las Navajas and Zacualtipán, in the Sierra de Pachuca. Here primitive mines to extract green obsidian, arrow heads, scraping tools, and mammoth remains can be traced back as far as 12,000 BCE. An ancient pre-Hispanic obsidian tool-making center has also been found in the small town of San Bartolo near the city. Around 2,000 BCE nomadic groups here began to be replaced by sedentary peoples who formed farming villages in an area then known as Itzcuincuitlapilco, of which the municipality of Pachuca is a part. Later artifacts from between 200 CE and 850 CE show Teotihuacan influence with platforms and figurines found in San Bartolo and in Tlapacoya. Development of this area as a city, however, would lag behind other places in the region such as Tulancingo, Tula and Atotonilco El Grande, but the archeological sites here were on the trade routes among these larger cities.

After the Teotihuacan era, the area was dominated by the Chichimecas with their capital in Xaltocan, who called the area around Pachuca Njunthé. Later, the Chichimecas would found the dominion of Cuauhtitlán pushing the native Otomis to the Mezquital Valley. These conquests coalesced into a zone called Cuautlalpan, of which Pachuca was a part. Fortifications in the area of Pachuca city and other areas were built between 1174 and 1181. This dominion would eventually be overrun by the Aztec Triple Alliance between 1427 and 1430, with rule in Pachuca then coming from the city of Tenochtitlan. According to tradition, it was after this conquest that mineral exploitation began here and in neighboring Real del Monte, at a site known as Jacal or San Nicolás. The Aztec governing center was where Plaza Juárez in Pachuca city is now.

The Spanish arrived here in 1528, killing the local Aztec governor, Ixcóatl. Credit for the Spanish conquest of the Pachuca area has been given Francisco Téllez, an artilleryman who came to Mexico with Hernán Cortés in 1519. He and Gonzalo Rodriguez were the first Spaniards here, constructing two feudal estates, and calling the area Real de Minas de Pachuca. Téllez was also given credit for laying out the colonial city of Pachuca on the European model but this story has been proven false, with no alternative version. Mining resources were not discovered here until 1552, and there are several versions of this story. The most probable comes from a work called "Descripción Anónima de la Minas de Pachuca" (Anonymous Description of the Mines of Pachuca) written between the end of the 16th century and the beginning of the 17th. This work claims that the first mineral deposits were found by Alonso Rodríguez de Salgado on his ranch on the outskirts of Pachuca in two large hills called Magdalena and Cristóbal. This discovery would quickly change the area's economy from agriculture to one dependent almost completely on mining.

As early as 1560 the population of the city had tripled to 2,200, with most people employed in mining in some way. Because of this rapid growth and the ruggedness of the terrain, it was impossible to lay out an orderly set of streets. The first main plaza was placed next to the Asunción Parish, which is now the Garden of the Constitution. Next to the Cajas Reales (Royal Safe) was constructed to guard the fifth that belonged to the king. In 1554, on the Purísima Concepción Hacienda, now the site of a tennis club, Bartolomé de Medina found the largest mineral deposits here as well as developed new ways of extracting minerals from ore using the patio process. This caused Pachuca to grow even more with the discovery of new deposits and accelerated extraction processes. Mining operations spread to nearby areas such as Atotonilco, Actopan, and Tizayuca. The population of the town continued to grow, leading Pachuca to be declared a city in 1813.

Mining output had waned by the 18th century due to flooding, but was revived in 1741 by the first Count of Regla, Pedro Romero de Terreros, and his business partner Jose Alejandro Bustamante, who invested in new drainage works. He also discovered new veins of ore, mostly in nearby Real del Monte. By 1746, Pachuca had a population of 900 Spanish, mestizo, and mulatto households, plus 120 Indian ones.

During the Mexican War of Independence, the city was taken by Miguel Serrano and Vicente Beristain de Souza in 1812, which caused the mines here to be abandoned by owners loyal to Spain. The war left the Pachuca area in a state of chaos, both politically and economically. The third Count of Regla brought the first Cornish miners and technology around 1824. The Cornish took over mines abandoned by the Spanish, bringing 1,500 tonnes of more modern equipment from Cornwall. Cornish companies eventually dominated mining here until 1848, when the Mexican–American War forced them to sell out to a Mexican company by the name of Mackintosh, Escondón, Beistegui and John Rule. Mining operations resumed in 1850, especially in the Rosario mine.

Mining operations were disrupted again by the Mexican Revolution in the early 20th century. The city was first taken by forces loyal to Francisco I. Madero in 1911. Roberto Martinez y Martinez, a general under Pancho Villa, entered the city in 1915. Both incursions were due to the economic importance of the mines here. During this time American investors came to Pachuca, again updating the mining technology used here. From 1906 to 1947 the United States Smelting, Refining and Mining Company was the primary producer here, with output reaching its peak in the 1930s. However, by 1947, mining here had become too costly, because of political instability, labor disputes and low prices for silver on the world market. The company sold its interests to the Mexican government in 1965.
