The economic consequences to the mines of Pachuca and Real del Monte during the War of Independence were ruinous. In 1824, British mining companies were brought in to revive the sector. The British introduced steam-powered machinery and other modern techniques as well as a large quantity of Cornish miners. Many of these Cornish miners stayed and English names and foods such as pasties (called “pastes” in Spanish) help define the state, especially in the Pachuca and Real del Monte areas. These Englishmen were forced to sell their interest to Mexican capitalists in 1849, and the mining sector fell again.
