The former Catalan president, Carles Puigdemont, once again resides in Belgium. He first fled to the country in order to escape conviction for sedition and rebellion by the Spanish state after he (formally) declared the independence of Catalonia on 27 October 2017. Ever since, the Spanish government and judiciary have tried to convince other European states to arrest him and send him back to Spain for trial. So far, they have been unsuccessful. Following a short period during which he was under arrest in Germany, Puigdemont is now back in Belgium.

The Russian Revolution took place during World War One: war and peace were critical issues. The overthrow of the Tsar and the establishment of a democratic government in February 1917 were regarded by the Provisional Government, and by the SR and Menshevik majority in the Petrograd Soviet, as a justification for continuing the support of the war effort in the name of the defence of the revolution.
