Sture (Swedish: [ˈstʉ̌ːrɛ]) was a name borne by three distinct but interrelated noble families in Sweden in the Late Middle Ages and Early Modern Period. It was originally a nickname, meaning 'haughty, proud' (compare the Swedish word stursk and the Old Norse and Icelandic personal name Sturla), but later became a surname. Particularly famous are the three regents (Swedish: riksföreståndare) from these families who ruled Sweden in succession during the fifty-year period between 1470 and 1520, namely: Sten Sture the Elder, regent 1470–1497 and 1501–1503. Svante Nilsson, regent 1504–1512.
