Csány took part in the politics of Zala County. He supported the reform policy of Ferenc Deák and became one of the leaders of the liberal opposition in the county. There was a disloyalty trial against him because of his anti-government speeches in 1838. He became a faithful and enthusiastic supporter of Lajos Kossuth in the early 1840s. He published articles for the "Pesti Hírlap" and was a founding member of the "Védegylet" defence society. He was a member of the Opposition Circle and thus a participant in the revolutionary events of March 1848.
