Stolypin changed the nature of the First Duma to attempt to make it more willing to pass legislation proposed by the government. On 8 June 1907, Stolypin dissolved the Second Duma, and 15 Kadets, who had been in contact with terrorists, were arrested; he also changed the weight of votes in favor of the nobility and wealthy, reducing the value of lower-class votes. The leading Kadets were ineligible. This affected the elections to the Third Duma, which returned much more conservative members, more willing to cooperate with the government. It changed Georgy Lvov from a moderate liberal into a radical.
