Juan Jufré was the governor of the Argentine province that historially comprised which provinces?
Cuyo (Argentina) Cuyo is the name given to the wine-producing, mountainous area of central-west Argentina. Historically it comprised the provinces of San Juan, San Luis and Mendoza and was influenced by Chile. The modern term New Cuyo indicates both Cuyo proper and the province of La Rioja. New Cuyo is a political and economic macroregion, but culturally La Rioja is part of the North-West rather than of Cuyo.
Argentine Confederation The Argentine Confederation (Spanish: "Confederación Argentina") is one of the official names of Argentina according to the Argentine Constitution, Article 35. It was the name of the country from 1831 to 1852, when the provinces were organized as a confederation without a head of state. The governor of Buenos Aires Province (Juan Manuel de Rosas during most of the period) managed foreign relations during this time. Under his rule, the Argentine Confederation resisted attacks by Brazil, Bolivia, Uruguay, France and the UK, as well other Argentine factions during the Argentine Civil Wars.
