Decolonising Museums is the second thematic publication of L'Internationale Online; it addresses colonial legacies and mindsets, which are still so rooted and present today in the museum institutions in Europe and beyond. The publication draws from the conference Decolonising the Museum which took place at MACBA in Barcelona, 27–29 November 2014 (among the contributors to this thematic issue, Clémentine Deliss, Daniela Ortiz and Francisco Godoy Vega participated at this seminar), and offers new essays, responding to texts published on the online platform earlier this year.
