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 III of Scotland
Alexander died in a fall from his horse while riding in the dark to visit the queen at Kinghorn in Fife on 18 March 1286 because it was her birthday the next day. He had spent the evening at Edinburgh Castle celebrating his second marriage and overseeing a meeting with royal advisors. He was advised by them not to make the journey to Fife because of weather conditions, but he travelled anyway. Alexander became separated from his guides and it is assumed that in the dark his horse lost its footing. The 44-year-old king was found dead on the shore the following morning with a broken neck. Some texts have said that he fell off a cliff. Although there is no cliff at the site where his body was found, there is a very steep rocky embankment, which "would have been fatal in the dark." After Alexander's death, his strong realm was plunged into a period of darkness that would eventually lead to war with England. He was buried in Dunfermline Abbey.
