Nicholas II of Russia
On 1 March 1881, following the assassination of his grandfather, Tsar Alexander II, Nicholas became heir apparent upon his father's ascension as Alexander III. Nicholas and his other family members bore witness to Alexander II's death, having been present at the Winter Palace in Saint Petersburg, where he was brought after the attack. For security reasons, the new tsar and his family relocated their primary residence to the Gatchina Palace outside the city, only entering the capital for various ceremonial functions. On such occasions, Alexander III and his family occupied the nearby Anichkov Palace.
Constantine I of Greece
King Alexander died on 25 October 1920, after a freak accident: he was strolling with his dogs in the royal menagerie, when they attacked a monkey. Rushing to save the poor animal, the king was bitten by the monkey and what seemed like a minor injury turned to septicemia. He died a few days later. The following month Venizelos suffered a surprising defeat in a general election.
