On October 1, 2017, Catalonia held a referendum on the region's independence from Spain. The vast majority of voters backed secession. The plebiscite was not, however, recognized by Madrid, which subsequently imposed direct rule over the autonomous region and dismissed its government.
Spanish authorities have opened a criminal case against 30 Catalan politicians and officials, arresting four of them, while Puigdemont, as well as several advisers of the dissolved Catalan government, fled Spain before the trial.
