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.
Stepan Khalturin
Under the orders of the Narodnaya Volya, Khalturin constructed a mine on February 17, 1880 in the basement of the building under the dining-room. The mine was set to go off at the time which Narodnaya Volya had calculated the Tsar to be having dinner. Unfortunately for the assassins, Alexander II's guest Prince Alexander of Battenberg arrived late, delaying dinner so the dining-room was empty. The Tsar was thus able to escape assassination unharmed though 11 Imperial Guards were killed and 45 more people were badly wounded by the explosion.
