The United States of Venezuela (Spanish: Estados Unidos de Venezuela) was the official name of Venezuela, adopted in its 1864 constitution under the Juan Crisóstomo Falcón government. This remained the official name until 1953, when the constitution of that year renamed it the Republic of Venezuela. In 1999 under newly elected president Hugo Chavez and his modification to the Constitution, Venezuela's official name became the Bolivarian Republic of Venezuela.[1]
