Meanwhile the question of eastern Rumelia, or rather southern Bulgaria, still a Turkish province, began to loom. A vigorous agitation for the reunion of the two parts of the country had been going on for some time, and on September 18, 1885, the inhabitants of Philippopolis suddenly proclaimed the union under Prince Alexander, who solemnly announced his approval at Tirnovo and triumphantly entered their city on September 21.
