Swedish prince and Duke of Västmanland, as the third and youngest son of King Gustaf V of Sweden and his queen, Victoria of Baden. In 1904, Prince Erik was appointed a Knight of the Norwegian Lion by his paternal grandfather, King Oscar II.
Prince Erik had epilepsy and mild intellectual disability. His exact condition has not been published, but he may have suffered an injury at birth. He was described as handsome and physically healthy.
Because of his condition, he was seldom seen in public and led a quiet life away from the public eye, similar to the life of Prince John of the United Kingdom. Because he was a member of the royal family, he was present in official royal photographs, but he had no official tasks.
He died on 20 September 1918, aged 29, in Drottningholm Palace, Stockholm.
