In May 1926, Piłsudskiite forces conducted the May Coup, deposed the legally-elected government and installed their own. The "Sanacja" political camp was formed, and Piłsudski's power grew. The "Sanacja" began to strengthen its own power and to curb the activities of opposition political parties. Many parties in that time became Piłsudskiite to get closer to power and stay safe from potential problems.
