Middle Ages Many Croatian archaeological sites, such as
Bočaj,
Basarica, Ribnik/grad Kosinj, Pisani kamen, Prespa,
Mlakvena Greda etc. state that there was evidence of life in the valley since the Roman era. Many medieval and historical records say that the city Ribnik or Kosinjgrad or Lasch de Kosin, the princes who reigned the year of our Lord mentions Kosinjski first in the year 1071 in the charter of the Croatian king
Peter Krešimir IV.
Renaissance One of the oldest printers in south Slavic, that wrote in Glagolitic breviary, was the first and oldest book known to have been printed on Croatian soil using the
Gutenberg press. An incomplete copy is kept in the Library Marciana in
Venice, and a smaller fragment (six parchment leaves) was discovered in the Vatican Library. A short time after the printing press was invented, founded by the princes
Frankopans in the village of Kosinj, the first Croatian printing. It was printed, also for ecclesiastical purposes, and the first Croatian printed book in the year 1483. Kosinj, as a symbol of Croatian culture, has its place in the
Gutenberg Museum in
Mainz, where the first map of printers contains the name of Kosinj.
Ottoman Era The Kosinj area remained after the Turks from the end of thirty Vlach families. They are the Krajina authorities have expressed the wish to remain in their homes. Since the end Kosinj remained rather poorly populated, Krajina administration has moved here from the Croatian settlers
Ogulin and upper
Pokuplje. The description of Kosinj by Bishop Glavinić, says that this place is divided into Upper, Middle and Lower Village. In the Upper Kosinj Glavinić is found forty houses of Croatian immigrants from Pokuplje. In the Middle Kosinj, a hundred houses Vlach population, lived in the Lower Kosinj Croats who moved here from Ogulin. In all three Kosinj village was then about 400 Croats and 300 Blaise. The Border writings known as the surnames of immigrants who are late 17th century welcomed to Kosinj. In later development Kosinje Central Village changed its name to
Zamost. Thus up to now remained only 2 Kosinje, Lower and Upper. The upper creek is about Bakovac and its compositions with the river Lika, and the lower few kilometers further north along the creek mentioned. ==Geography==
