On 29 March Gustav IV Adolf, to save the crown for his son, voluntarily abdicated; but on 10 May the Riksdag of the Estates, dominated by the army, declared that not merely Gustav but his whole family had forfeited the throne, perhaps an excuse to exclude his family from succession based on the rumours of his illegitimacy. A more likely cause, however, is that the revolutionaries feared that Gustav's son, if he inherited the throne, would avenge his father's deposition when he came of age. On 5 June, Gustav's uncle was proclaimed King Charles XIII, after accepting a new liberal constitution, which was ratified by the diet the next day. In December, Gustav and his family were transported to Germany. In 1812, he divorced his wife.
