San Juan is a province located in the North West of Argentina, bordered by La Rioja on the Northeast, San Luis on the Southeast, Mendoza on the South, and Chile (and the Andes) on the West.
The capital of San Juan is the city of San Juan. Being a mountainous province, the majority of the population lives within valleys in the centre of the province, and along the Andes in the West.
San Juan used to be home to a number of native populations that were influenced by the Incan Empire. Though there have been many clashes with European settlers, there are still a number of native people that still live in the province.
There are a number of paleontological sites within the province of San Juan, probably due to its mountainous geography.
The flag of San Juan was created in 1997. The blue and white of the flag are the same as the blue and white on the national flag of Argentina. In the centre of the flag is San Juan's coat of arms. The blue half of the coat of arms represents San Juan's blue skies, and the white is for the snow of the Andes. On the top of the arms is the Incan sun with eighteen points for each department of the province, and along the sides are two laurel branches symbolizing agriculture and victory. Joining the laurels is a ribbon representing the country of Argentina. The hands in the middle represent unity, and behind them is the constitution. On top of the constitution is a Phrygian cap, which represents a republic (just as a crown usually represents a monarchy).
The name "San Juan" comes from the capital city of the same name. The city was founded in 1561 by the Spanish conquistador Juan Jufré, and he named the city after John the Baptist.
