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.
Alexander the Great
On either 10 or 11 June 323 BC, Alexander died in the palace of Nebuchadnezzar II, in Babylon, at age 32. There are two different versions of Alexander's death and details of the death differ slightly in each. Plutarch's account is that roughly 14 days before his death, Alexander entertained admiral Nearchus, and spent the night and next day drinking with Medius of Larissa. He developed a fever, which worsened until he was unable to speak. The common soldiers, anxious about his health, were granted the right to file past him as he silently waved at them. In the second account, Diodorus recounts that Alexander was struck with pain after downing a large bowl of unmixed wine in honour of Heracles, followed by 11 days of weakness; he did not develop a fever and died after some agony. Arrian also mentioned this as an alternative, but Plutarch specifically denied this claim.
