The overthrow of King Ferdinand VII of Spain as a result of the Peninsular War in Spain suddenly increased the prospect of independence for the Spanish colonies in the Americas. The meetings in Ortiz de Domínguez's house became the official location of the revolutionary conspiracy and much of the insurgent planning was carried out there, including gathering weapons and supplies and storing them in various houses. The beginning of the revolution was planned for December 8, 1810. However, on September 13, the conspirators were betrayed by a supporter, who informed the Spanish colonial authorities about rebel activities in Querétaro. The colonial authorities, unaware of Domínguez's wife's allegiance, asked the Corregidor to conduct a search in the town in order to apprehend the rebel leaders. He imprisoned his wife Ortiz de Domínguez in her room to prevent her from exchanging information with her fellow conspirators.
