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.
Narodnaya Volya
The assassination of Tsar Alexander II on March 1 (13), 1881, marked the high-water mark of "Narodnaya Volya" as a factor in Russian politics. While the assassination did not end the Tsarist regime, the government ran scared in the aftermath of the bomb that killed him, with the formal coronation ceremony of Tsar Alexander III postponed for more than two years due to security concerns.
