After the revolt in 1825 the new tsar Nicholas I realized that Pushkin was by now very famous. He also realized that he had not taken part in the revolt, so he allowed him to return. The tsar said that he himself would censor Pushkin's works before they were allowed to be published. He said that he was going to be a good tsar and help the poor people (the serfs) to become free. Pushkin was in a difficult position because he could not write anything that the tsar would not like.
