The election followed the parliamentary reform of 1906 which replaced the Diet of Finland, which was based on the Estates and had its institutional roots in the period of Swedish reign, with a modern unicameral parliament of 200 MPs. The reform was agreed upon after a general strike in Finland in 1905 during which demands for a parliamentary reform arose especially among the Socialists. This coincided with similar development in Russia which too saw a general strike and, after the Russo-Japanese War, the birth of a new institution, the Duma. This background explains why Emperor Nicholas II of Russia allowed the parliamentary reform in Finland.
