The Catalan Republic Collapses

The Catalan Republic was a short-lived unrecognized secessionist state that was declared on 27 October 2017. The Parliament of Catalonia unilaterally declared independence from Spain amid a constitutional crisis over the result of the 2017 Catalan independence referendum. By 30 October, Spanish authorities had reasserted control over Catalan territory with little resistance, with the independence declaration being suspended by the Constitutional Court of Spain on the next day.

Shortly after the Catalan parliament declared independence from Spain, the Spanish Senate triggered Article 155 of the Spanish Constitution of 1978, and Prime Minister Mariano Rajoy dismissed the Executive Council of Catalonia, dissolving the Parliament of Catalonia and calling a snap regional election for 21 December 2017. In response, Carles Puigdemont, President of the Generalitat of Catalonia, stated that only parliaments could elect or remove governments in a democratic society and asked Catalans to "democratically oppose" the enforcement of Article 155, without clarifying what his response would be to the Spanish government's orders.

By 30 October, work had resumed as normal throughout Catalonia as the Spanish government's takeover met with little resistance from Catalan authorities. Puigdemont and part of his cabinet fled to Belgium to escape action from the Spanish judiciary, having been formally accused of rebellion, sedition and embezzlement by the Spanish Attorney General.
