Historiography of the May Revolution
The last years of the 19th century and the beginning of the 20th were marked in Argentina by a growing industrialization process and the arrival of huge numbers of European immigrants. Historiographical studies were increased by the ""New Historical school"", in order to forge a "national identity", and the May Revolution had great prominence. There were discussions about the level of influence that the many causes of the May Revolution actually had, or whose interventions were the most decisive, but two points shared by all historians were to consider the May Revolution as the birth of Argentina, and to consider it an inevitable consequence of the causes that led to it (meaning, the chance of the May Revolution never taking place is not considered a feasible possibility by historians). There was also a subtle change: the scope of the revolution as a subject of study originally "started" with the events of May 1810 in Buenos Aires and kept going on for decades. They were later split, and the name "May Revolution" made reference only to events that led to the removal of Cisneros and the creation of the Primera Junta. A new element added by those historians was to consider, either to support or reject the idea, whenever there was an active and strong popular support for the Revolution, instead of explaining it solely around the actions of a limited number of enlightened men. Nevertheless, they kept the previous approaches for the most part.
International Workers' Day
May Day was celebrated illegally in Russia until the February Revolution enabled the first legal celebration in 1917. The following year, after the Bolshevik seizure of power, the May Day celebrations were boycotted by Mensheviks, Left Socialist Revolutionaries and anarchists. It became an important official holiday of the Soviet Union, celebrated with elaborate popular parade in the centre of the major cities. The biggest celebration was traditionally organized in Red Square, where the General Secretary of the CPSU and other party and government leaders stood atop Lenin's Mausoleum and waved to the crowds. In 1991, which preceded the last year that demonstrations were held in Red Square, May Day grew into high-spirited political action. Around 50,000 people participated in a rally in Red Square in 1991 after which the tradition was interrupted for 13 years. In the early post-Soviet period the holiday turned into massive political gatherings of supporters of radically minded politicians. For instance, an action dubbed as "a rally of communist-oriented organisations" was held in Red Square in 1992. The rally began with performance of the Soviet Union anthem and raising the Red Flag and ended with appeals from the leader of opposition movement Working Moscow, Viktor Anpilov, "for early dismissal of President Boris Yeltsin, ousting Moscow Mayor Gavriil Popov from power and putting the latter on trial". Since 1992, May Day is officially called "The Day of Spring and Labour", and remains a major holiday in present-day Russia.
