assurance that once the negotiations with Serbia were complete, Britain would accept the amendment of Article 25. Without such assurance Austria-Hungary stated it would break off negotiations with Serbia. Later that day Austria-Hungary decided to partially mobilize its armed forces. On 28 March Britain committed as requested. On 31 March Serbia made its formal declaration of acceptance to Austria-Hungary representing a complete Serbian climb down. The crisis was over. The Great Powers signed the amendments to the Treaty of Berlin in the various capitals from 7 to 19 April. A little over a year later, as a result of this diplomatic defeat, Izvolsky was demoted and made ambassador to France. He was permanently embittered against Aehrenthal and the Central Powers. The Russian diplomat and newspaperman de Schelking relates Izvolsky's political downfall: "In the Salons of Petrograd he was given the Sobriquet 'Prince of the Bosphorus'. In his conceit, Izvolsky could not see he was being mocked." Notes References Citations Primary sources Secondary sources Carroll, E. Malcolm.
