Berry was the only member of the family thought to be able to beget children. His wife gave birth to a posthumous son in September, Henry, Duke of Bordeaux, nicknamed "Dieudonné" (God-given) by the Bourbons because he was thought to have secured the future of the dynasty. However the Bourbon succession was still in doubt. The Chamber of Deputies proposed amending Salic law to allow the Duchess of Angoulême to accede to the throne. On 12 June 1820, the Chambers ratified legislation that increased the number of deputies from 258 to 430. The extra deputies were to be elected by the wealthiest quarter of the population in each département. These individuals now effectively had two votes. Around the same time as the “law of the two votes”, Louis began to receive visits every Wednesday from a lady named Zoé Talon, and ordered that nobody should disturb him while he was with her. It was rumoured that he inhaled snuff from her breasts, which earned her the nickname of "tabatière" (snuffbox). In 1823, France embarked on a military intervention in Spain, where a revolt had occurred against the King Ferdinand VII. France succeeded in crushing the rebellion, in a campaign headed by the Duke of Angoulême.
