Anund Jacob or James (Old Norse: Ǫnundr Jakob; Swedish: Anund Jakob; c. 25 July 1008/10 - c. 1050) was King of Sweden from 1022 until around 1050. He is believed to have been born on 25 July, in either 1008 or 1010 as Jakob, the son of King Olof Skötkonung and Queen Estrid. Being the second Christian king of the Swedish realm, his long and partly turbulent reign saw the increasing dissemination of Christianity as well as repeated attempts to influence the balance of power in Scandinavia.
