During his short life, Carl Oskar was second in line to the throne of Sweden and Norway, after his father, and was also Duke of Södermanland. As a result of his early death and his father's lack of legitimate male heirs, his uncle, Prince Oscar Fredrik eventually inherited the throne of Sweden and Norway as King Oscar II.
Death
In February 1854 the young prince suffered from measles and was prescribed a cold bath. This led to pneumonia and the prince Carl Oskar died of the disease, in Stockholm palace, at the age of just 15 months on 13 March 1854. He is interred in a royal vault of the Riddarholmen Church in Stockholm, Sweden.
