During the latter part of the eighteenth century a new hope came to the Serbs in the growing development of their national literature. A school was founded at Carlowitz by the Patriarch of the Serbs; printing-presses were set up, and writers were gradually produced by this education, one of whom, named Obradoviç, composed the first essay in the Serb dialect: while Karadziç, another writer, gathered up the old songs, proverbs, and stories of the country and tried to reduce the dialect into grammatical forms. The movement of Szaffarik and Kollar in North Hungary gave new hopes to the Serbs and other Slavs in the development of their literature; and it was whilst this feeling was growing that Gaj put forward his plan for the Illyrian language. Gaj's movement was, to some extent, an apple of discord among the Serb national party; for, while some of them were eager to join in any union of the Slavs, many of the more powerful of the clergy objected altogether to the abandonment of the old Cyrillic alphabet which had been introduced by the Bishops Cyril and Methodius, who converted the Slavs to Christianity. And while, as was mentioned in a former chapter, Gaj was suspected by the Roman Catholics of wishing to swamp them in a union with the members of the Greek Church, the Greek clergy among the Serbs, on the other hand, feared a movement which seemed likely to have its centre in the Roman Catholic province of Croatia. Thus there had grown up two centres of the Serb movement in two towns situated within a few miles of each other. Neusatz, or Novi Sad, the most important town of Slavonia, was the centre of the literary and trading part of the Serb community; and Carlowitz, or Karlovci, was the head-quarters of the Metropolitan, and the centre of the clerical section of the Serb national party.
