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.
John Ruthven, 3rd Earl of Gowrie
John Ramsay (afterwards the Earl of Holdernesse), noticing a small, dark stairway leading directly to the inner chamber adjoining the turret, ran up it and the door was then unlocked by Henderson. There he found the king struggling with Alexander. Drawing his dagger, Ramsay wounded Alexander, who was then pushed down the stairway past the king. Thomas Erskine, summoned by Ramsay, now followed up the small stairs with Dr Hugh Herries, and the two killed Alexander with their swords. John Ruthven, entering the courtyard with his stabler Thomas Cranstoun and seeing his brother's body, rushed up the staircase after Erskine and Herries, followed by Cranstoun. In the melée he was also killed. Some commotion was caused in the town by the noise of these proceedings but it quickly subsided, though the king did not deem it safe to return to Falkland Palace for some hours.
