Early history In Grožnjan are found ancient Roman artifacts and near Grožnjan is the remains of a Roman house, but the first mention of Grožnjan dates from 1102, when
Margrave of Istria Ulric II and his wife Adelaida granted their land to
Patriarch of Aquileia. In this document the fort is called
Castrum Grisiniana. In 1238 Grožnjan was the property of Vicardo I Pietrapalosa. In 1286, Grožnjan fort was lent to the Aquileian patriarch during war with
Venice but changed sides in 1287, and Grožnjan was given to Venice. Vicardo's son Pietro inherited Grožnjan after his father's death in 1329, and when he died in 1339 it again became the patriarch's property. The patriarch rented it to a
Friuli noble family, de Castello. In 1354 Grožnjan's new owner became Volrich, or Ulrich, Reifenberg, who in 1358 sold it to Venice for 4,000 ducats in order to pay his debts. Volrich was a son of Deitalm, a descendant of Aquileian patriarch Volcher, and in 1356, during the war between Venice and
Hungary, his army, entrenched in Grožnjan, strongly resisted the Hungarian army. Yet it seems that at the same time Volrich negotiated the surrendering of Grožnjan in Venice.
Venetian Republic Venice took Grožnjan over in 1358 and ruled until the demise of the Venetian Republic in 1797. In 1359 the
Umag captain Pietro
Dolfin moved to his new residence in Grožnjan, and in 1360 and 1367 he fortified the town walls and renovated the palace. Captain's Office moved from Grožnjan to Raspo in 1394, when a central rule was established for the whole area. Since then Grožnjan was governed by Venetian noblemen who were given the title of "
Mayor". From the early 16th century Grožnjan's mayors were chosen among
Koper noblemen. In the 15th century judicial duties were performed by the Pietrapelosas, and in 1446 the town walls were fortified in order to protect it from possible Turkish attacks. After the terrible plague in 1630 the Grožnjan area became almost completely deserted. In order to revitalize the area the St. Mark's Republic brought Italian families from
Veneto and
Friuli; these were mostly tradesmen who settled in towns. Settlers were invited by the
Republic of Venice to cultivate the abandoned land in some hamlets around Grožnjan. Most of the settlers were
Morlachs from
Dalmatia, but also Slavic people,
Albanians and
Greeks, all refugees of the
Ottoman Empire. All settlers in Istria were given free land and were exempt from fiscal duties and work obligations for twenty years; the only condition was to cultivate the land within five years. The economic success of the colonization of villages was reflected in the towns as well: trade and transportation developed and demographics improved.
Austrian Empire After the fall of
Napoleon's Empire in 1813, his
Illyrian Provinces, including Grožnjan, became part of the
Austrian Empire. In 1816 the Austrian Emperor
Francis II visited Grožnjan on his tour through Istria and met with the local clergy and population. During Austrian rule, the Grožnjan area flourished. The building of the
Parenzana railroad in 1902 enhanced the development of trade and agriculture. Wine, olive oil, eggs, and other produce were sold in
Koper and
Trieste. According to the 1910 census, the settlement of Grožnjan had 1,658, and the municipal area had 4,028 inhabitants. The town had a doctor, a post office, a school, a lawyer, a notary public, an oil processing plant, a bakery, groceries and clothing stores, two butchers, several inns, and various trade shops (shoemakers, blacksmiths, tailors, carpenters, etc.).
Kingdom of Italy The dissolution of the Austrian Empire, the subsequent Italian rule and the
Great Depression had its consequences. In the 1920s people started to emigrate, looking for work in
Trieste and overseas. During the rule of the
Kingdom of Italy Grožnjan attained waterworks, the area was electrified, and the
Mirna river valley was reclaimed.
SFR Yugoslavia After the
Second World War, Istria was divided into two parts, the Yugoslav one and the
Free Territory of Trieste, which was divided into Zone A, controlled by the US Army, and Zone B, controlled by the
Yugoslav Army. Grožnjan becomes a part of Zone B. On October 5, 1954, the
London Memorandum was signed and Zone A was assigned to Italy, and Zone B to the
People's Federal Republic of Yugoslavia. In 1975 the
Treaty of Osimo divided the Free Territory of Trieste and Grožnjan became part of Yugoslavia. The London Memorandum provided the population with the option of emigration to Italy. The new Yugoslavia's emergent communist system and its application, along with lingering hostilities between Italians and Yugoslavs (like the murder of priest
Francesco Bonifacio), contributed to a large wave of emigration (part of the
Istrian–Dalmatian exodus). By April 1956, 2/3 of the population emigrated from the area to Italy. In 1955 Grožnjan lost its municipality status and became part of the municipality of
Buje. In 1965, when the Town of Arts was founded, some of the housing was given to artists from Croatia, Slovenia, and Vojvodina, and some were assigned to the Cultural Centre of the International Music Youth Federation in 1969. In 1993 Grožnjan got its municipality status again. ==Demographics==
