The Serbian authorities acted terribly when they took control of Kosovo in the late 1980s: in terms of education, they put an end to teaching in Albanian with measures such as the widespread dismissal of Albanian teachers and the closure of schools. One of the most bloody episodes of this persecution took place in March 1990 when between 4,000 and 8,000 students and teachers were poisoned throughout Kosovo. Those events provoked a wave of collective mobilisations. An icon of this is the ruins of the Hertica school, one of the 400 that were created in private homes in Kosovo's capital, Pristina, in order to be able to teach in Albanian, albeit clandestinely. Until October 30, this school opens its doors to the public as one of the twenty-five spaces of the 14th edition of Manifesta, the travelling biennale which will be held in Barcelona in 2024.
