VENETIAN SUPREMACY
he would remain at peace with Michael for so long as the latter’s treaty with Ragusa lasted.1
  The archbishop, who had been the original cause of all the trouble, had naturally become extremely unpopular, and when in his zeal for Venetian supremacy he proposed to carry out the provision of the treaty of 1232 by placing himself under the authority of the Patriarch of Grado, his position became untenable, and he was forced to abdicate (1257). The Ragusans obtained from the Pope that his successor should not be a Venetian. Another Venetian, however, was appointed in 1276.
  In 1266 the quarrel with Servia broke out afresh. The King was angry, according to Resti, because a number of his nobles quitted the country and settled at Ragusa. This statement, if true, is interesting, as it is the first immigration of Slaves on a large scale into the city after the early settlements between the seventh and the tenth centuries. But again the quarrel was settled by stanico, and the Ragusans agreed to pay Uros the tribute of 2000 ipperperi in exchange for increased privileges and the confirmation of their rights over the disputed territories at Breno, Gionchetto, &c.2
   The year 1272 is a very important one in Ragusan annals, as it is the date of the promulgation of the statute-book by the Count Marco Giustiniani. Hitherto the constitution and laws of Ragusa had been based on custom, altered and modified by statutes. Giustiniani codified all the existing sources of Ragusan jurisprudence
