caption_attribution_description: English: The border between Brazil (Chuí) and Uruguay (Chuy).
context_page_description: Chuy is a city in the extreme east of Uruguay, in the Rocha Department, 340 kilometres northeast of Montevideo. It lies on the border with Brazil, separated from its Brazilian sister town of Chuí only by a shared avenue that serves as the border, and by the Arroyo Chuy to the east. Chuy's population is currently 9,675 residents as of 2011.
context_section_description: In the late 17th century, Portugal and Spain began the occupation of the Banda Oriental; they succeeded in founding Colonia del Sacramento in 1680, Montevideo in 1726, the Fuerte de San Miguel in 1737, and the Fortaleza de Santa Teresa in 1762. The Treaty of Madrid (1750) settled boundaries between the mouth of the creek Valizas and Cabo Polonio. By order of the Governor of Montevideo, José Joaquín de Viana, in 1751, frontier military posts were created, with colonial guards on both sides of the Chuy stream, the result of the discussions that had prevailed in the courts of the Spanish and Portuguese crowns. The treaty expired in 1761 with the signing of the Treaty of El Pardo. In Europe came the Seven Years' War. At that time, Pedro de Cevallos ousted the Portuguese colony of Santa Teresa and San Miguel, and Chuy came to dominate the southern Rio Grande do Sul. The situation was unstable, however, and the signing of the Treaty of San Ildefonso on October 1, 1777 led to a clearer demarcation of dominions in South America.
  In 1762 after the surrender of Colonia del Sacramento, Pedro de Cevallos went to the Portuguese, demanding the "eviction of the Yacuí River and areas of Rio Pardo, Santo Amaro, Rio Grande, San Gonzalo, San Miguel and Chuy, as well as Martín García Island and Dos Hermanas Island." In 1763, the Military Command at Maldonado was created to take care of security in the east. In 1772 Bernardo Lecocq developed the fortifications of Fuerte de San Miguel here. Eventually, however, Spain would lose influence over these territories.
  For the sake of demarcating the Hispano-Lusitanian boundary, both Spain and Portugal brought to the area a significant number of scientists. Work in the Guardia de Chuy began in February 1784.
  It is presumed that in 1826, there was a farmhouse in Chuy, as Leonardo Olivera after the famous Sableada del Chuy, on the first day of the year, he wrote that it was a surprise to Brazilians, "leaving over twenty dead behind, as I mentioned to Your Excellency, I left a captain and a wounded soldier in a house of Chuy, not knowing where to take them, so that a certain family would take care of their wounds." The 1861 map of the area by Emilio Laviña includes a ranch, stalls and a store belonging to the firm Peyre Seijo & Co. In addition to this general trade store, there existed a chemist and a teacher named Marcelino Villazuso, who gave private lessons for many years. The growing importance of this border and the existence of military posts on the Brazilian side, prompted the authorities to install a police station or Comandancia de Frontera depending on Maldonado in 1872.
  In 1888, the town was recognized as such by the department. The Economic Administrative Board Rocha urged neighbours to form a Neighbourhood Commission (first authorities to address local issues), and these were grouped immediately notifying the Honourable Board Rocha.
  Uruguay and Brazil inherited differences resulting from the ongoing litigation, which would be amended in repeated boundary treaties with the placement of boundary markers in the twentieth century. On 7 May 1913, a convention was signed to amend the limit on the San Miguel river. On 20 December 1933 a Legal Status of Border was established and on 21 July 1972 bilateral notices were exchanged about the waterfront borders at the height of the mouth of the creek Chuy.
  On 14 January 1938, the status of Chui was elevated to "Pueblo" (village) by the Act of Ley Nº 9.758,. On 29 June 1961, it was elevated to "Villa" (town) by the Act of Ley Nº 12.887, and on 11 December 1981, it was further elevated to "Ciudad" (city) by the Act of Ley Nº 15.227.
