Russian Orthodox believers attend a religious service marking 100 years since the abdication of the last Tsar Nicholas II at a cathedral in Moscow's Kolomenskoye park on March 15, 2017. Nicholas II abdicated on March 2, 1917, or March 15 by the current calendar, after the February Revolution in Saint Petersburg, when troops mutinied as protestors demanded bread and condemned tsarism.
