The authorities of the Co-Princes banned casinos and betting houses throughout the country. The ban resulted in an economic conflict for the Andorran people. The conflict led to the so-called revolution of 1881, when revolutionaries assaulted the house of the syndic on 8 December 1880, and established the Provisional Revolutionary Council led by Joan Pla i Calvo and Pere Baró i Mas. The Provisional Revolutionary Council allowed for the construction of casinos and spas by foreign companies.
