The Andorran Revolution, also known as the Revolution of 1933, was a democratic uprising led by the Young Andorrans (a trade union related to the CNT-FAI) that called for political reforms, universal suffrage for all Andorrans and acted in defense of the rights of local and foreign workers during the construction of FHASA's hydroelectric power station in Encamp. On April 5, 1933, the Young Andorrans seized the Andorran Parliament. These actions were preceded by the arrival of Colonel René-Jules Baulard with 50 gendarmes and the mobilization of 200 local militias or sometent led by the Síndic Francesc Cairat.
