political instability that followed the first 50 years of the new country allowed two American invasions and an internal secession war, during which the governor of the state annexed Coahuila and Tamaulipas states, designating Monterrey as the capital of the Republic of the Sierra Madre as it did before in 1840 for the Republic of the Rio Grande. In 1846, the earliest large-scale engagement of the Mexican–American War took place in the city, known as the Battle of Monterrey. Mexican forces were forced to surrender but only after successfully repelling U.S. forces' first few advances on the city. The battle inflicted high casualties on both sides, much of them resulting from hand-to-hand combat within the walls of the city center. Many of the generals in the Mexican War against France were natives of the city, including Mariano Escobedo, Juan Zuazua (b. Lampazos de Naranjo, NL) and Jerónimo Treviño. The brewery Cervecería Cuauhtémoc, one of the milestone local enterprises, was founded in 1890. 20th century During the last decade of the 19th century, Monterrey was linked by railroad, which benefitted industry. It was during this period that José Eleuterio González founded the University Hospital, now one of northeast Mexico's best public hospitals, affiliated with the School of Medicine of the Autonomous University of Nuevo León (UANL). Antonio Basagoiti and other citizens founded the Fundidora de Fierro y Acero de Monterrey. A steel-producing company that accelerated the already fast industrialization of the city was founded in 1900 and became one of the world's biggest. In 1986, Monterrey hosted several games of the 1986 FIFA World Cup. In 1988, Hurricane Gilbert caused great damage to the city; the Santa Catarina River overflowed, causing about 100 deaths and economic damage. 21st century The city has hosted international events such as the 2002 United Nations Conference on Financing for Development with the participation of more than 50 heads of state and government, as well as other ministers and senior delegates from over 150 countries. The conference resulted in the adoption of the Monterrey Consensus, which has become a reference point for international development and cooperation. In 2004, the OAS Special Summit of the Americas was attended by almost all the presidents of the Americas. In 2007, Monterrey held the Universal Forum of Cultures, with four million visitors. In 2008, Monterrey held the FINA World Junior Championships. In 2010, Monterrey was hit by another damaging storm,
