Prince Carl Gustav, Duke of Småland

In March 1783 the young Prince suddenly took ill, probably from inappropriate food^[1] and died when he was little over a half year old. He was interred in Riddarholm Church in Stockholm.

His father took the death very hard and had never been seen so grief stricken, unable even to attend the little boy's funeral. After Carl Gustav's death Gustav III began new phases in his own life, travelling far away from Sweden, gradually increasing his power and starting war. Several writers have attributed the change in his personality and activity at least in part to his strong reaction at the death of his second son.^[2][3]
