Historians suggest that the capital and largest city of Sweden, Stockholm, was founded in 1187. There are two main theories about the origin of the city's name. According to one theory, it derives from the words "holme" (island) and "stack" (bay), meaning "island in the bay." The other theory suggests it refers to "stock" (piles), indicating an "island on stilts."
As of 2012, Stockholm's population had surpassed 870,000, with over 1.2 million people residing in the surrounding suburbs.
