In the course of the tenth century Ragusa was again besieged by barbarians—they were Bulgarians this time, under the Tsar Simeon (not Samuel, as had been stated), who invaded the western provinces of the Eastern Empire. According to Cedren, his attack on Ragusa failed,[43] whereas the Presbyter of Doclea writes that the town was burnt. It was during this same century that Ragusa first began to acquire territorial possessions. The account of the manner of these acquisitions is in part legendary; but, according to Prof. Gelcich, it has some substratum of fact. Paulimir Belo or Belus, King of Rascia,[44] having been deposed and exiled, took refuge in Rome, and married a Roman lady. In 950 he returned to Illyria, and landed at Gravosa, near Ragusa, with a large suite of Roman nobles. The Ragusans received him with great honours, and he in return helped them to enlarge their city, and sent a number of his followers, including some Romans, to increase the population. After this he returned to Rascia and regained his throne. As Prof. Gelcich observes, Rome is evidently a mistake for Rama, a country which forms part of the Herzegovina, and takes its name from a small river tributary to the Narenta. A few years later Stephen, Banus of Bosnia, and his wife, Margaret, came to Ragusa in order to fulfil a vow which the former had made to St. Stephen when his wife was ill, that he would visit the saint’s church in the city if she recovered. As a reward for the welcome accorded to him by the citizens he gave them the districts of Breno, Bergato (Brgat), Ombla, Gravosa, Malfi, and part of Gionchetto.
