Marie de Coucy
Alexander II died on 8 July 1249 during an expedition against the Lord of Argyll on the island of Kerrera. Immediately after the news reached her, Marie made sure her 8-year-old son was crowned as soon as possible at Scone. Although her son was a minor and was placed under regency, Marie did not become regent. On 9 June 1250 Marie and her son Alexander III were present in Dunfermline for the observance of the canonisation of Saint Margaret of Scotland and the transference of her remains to the new shrine.
Alexander Soloviev (revolutionary)
On the morning of 20 April 1879, Alexander II was briskly walking towards the Square of the Guards Staff and faced Soloviev. Having seen a menacing revolver in his hands, the Tsar fled. Soloviev fired five times but missed, and was sentenced to death. Soloviev was hanged on 28 May 1879 (in Julian calendar; June 9, 1879 in Gregorian calendar). Soloviev had acted on his own, but other revolutionaries were keen to murder Alexander, and there were several assassination attempts following this.
