Yes.
After being appointed Prime Minister of Russia in 1906, his first action was to clamp down on terrorism.
In 1906 alone, 1008 terrorists had been executed.
Stolypin also helped peasants to become owners of their own land (he did this because he believed this would help to prevent revolution)
Conditions in Russia began to improve (i.e. Industry grew, Wages increased, Harvests were good)
However, in 1911 Stolypin was assassinated (by one of his own police agents who turned out to be a terrorist)
