Joaquín de Montserrat, marqués de Cruillas (June 26, 1700 – November 21, 1771) was Spanish viceroy of New Spain, from October 6, 1760 to August 24, 1766.
Joaquín de Montserrat was named viceroy of New Spain early in 1760. The transfer of power was made September 19, 1760 in Otumba, and his formal entry into Mexico City was October 6, 1760.
Among his immediate and most important concerns was the organization of a true colonial army. As he passed through Puebla he reviewed a battalion of militia formed of Negroes and Mulattoes. Their arms were very irregular, and the new viceroy made a formal request to Spain for new rifles to arm them.
In 1761 there was an epidemic of smallpox that principally attacked the Indians. Estimates were 14,600 dead in Mexico City and up to 80,000 in Puebla. The government nearly emptied its coffers (hardly full to begin with) to provide what palliative assistance was possible. Viceroy Montserrat took economy measures, ordered the collection of back taxes, and prohibited hoarding of foodstuffs and merchandise.
On November 20, 1761, Mayas under Jacinto Canek rose in rebellion in Cisteil, Yucatan. Canek was captured, and on December 14, 1761 he was tortured and quartered in the plaza of Valladolid.
Other disasters during Montserrat's term of office included a major flood in Guanajuato that paralyzed the operation of the silver mines (April, 1762), and another epidemic (of "fever") that caused many deaths (1763).
He also had to send military assistance to Sonora, where a revolt of Pimas and Seris had broken out against their maltreatment by the Spanish colonists. The rebels had killed the garrisons of two presidios and the governor before escaping to the mountains, where they were finally subdued.
In January, 1762, after the accession of Charles III to the Spanish throne, Spain was again at war with England (the Seven Years' War). Havana fell to the English on August 13, 1762, and Veracruz was under imminent threat of a landing. Montserrat strengthened the fortifications at Veracruz and made sure they were well supplied. He raised more troops and ensured that they were organized and trained to fight effectively. To guard the trade merchandise, he organized two companies of grenadiers, of Negroes and Mulattoes. The population dubbed these "Los Morenos" (the dark-skinned ones). The merchants of Veracruz formed another company and paid their salaries, arms and equipment. Other battalions and regiments were raised in the provinces, including battalions in Valladolid, León, Puebla and Oaxaca. Cavalry and militia were also raised in the large cities.
