 The prince, after vainly endeavouring to obtain the recall of the generals, restored the constitution with the concurrence of all the Bulgarian political parties (19 September 1883).A serious breach with Russia followed, and the part which the prince subsequently played in encouraging the national aspirations of the Bulgarians widened that breach.The revolution of Plovdiv (18 September 1885), which brought about the union of Eastern Rumelia with Bulgaria, took place with Alexander's consent, and he at once assumed the government of the province.
