Oscar II (Oscar Fredrik; 21 January 1829 – 8 December 1907) was King of Sweden from 1872 until his death, and the last Bernadotte King of Norway from 1872 until his dethronement in 1905.
Oscar was king during a time when Sweden was undergoing a period of industrialization and rapid technological progress. His reign also saw the gradual decline of the Union of Sweden and Norway, which culminated in its dissolution in 1905. He was subsequently succeeded as King of Norway by his grandnephew Prince Carl of Denmark under the regnal name Haakon VII, and as King of Sweden by his eldest son, Gustaf V.
Harald V, the present king of Norway, is a great-grandson of Oscar II, through his third son Prince Carl, Duke of Västergötland.
