Žumberak Mountains

The highest peak, Sveta Gera / Trdina Peak, is subject to a border dispute between Croatia and Slovenia. An old Yugoslav People's Army barracks building stands there that is used as an outpost by the Slovenian Army since the 1990s, although it is recorded in the Croatian land registry, and Croatian side see this as an occupation of their land. Since then that has been a subject of a dispute between the two new countries.[4][5][6]

The situation became more complex when the dispute nearly derailed Croatia's application to join NATO. It escalated further with Slovenia's blockade of Croatia's EU accession from December 2008 until September–October 2009, when Slovenia (a European Union member state) blocked the negotiation progress of Croatia (at the time an EU candidate state). However, further escalation was prevented due to amicable diplomacy of the Croatian and Slovenian prime ministers Jadranka Kosor, and Borut Pahor.[7][8]

The earliest artefacts in the Žumberak Mountains, small axe, and fragments of a pot, were found in the village of Mrzlo Polje Žumberačko. They belong to the people of Baden culture (Lasinya culture).[11]

There is a large archaeological survey in Budinjak. Large settlement and a necropolis with 140 tumuli were discovered. One of the most important findings is bronze, Kneževa kaciga (Prince's Helmet), found in one of two biggest tumuli, with diameter of 19 meters 19 m (62 ft). Today it is in Archaeological Museum in Zagreb. This is a proof that Budinjak was a settlement with powerful economy which had contacts with faraway lands.[11]

In late Iron Age, the Celtic tribes started conquering and colonizing this part of Europe. It is presumed that they had many settlements in the Žumberak Mountains, since mint was discovered in Samobor. Under the Okić castle, in the forest of Jama near Podgrađe, a man found 1600 silver Celtic coins. These coins are now called Samobors.

In 35 - 33 BC the Žumberak Mountains became part of the Roman Republic, later empire, province of Pannonia. The most important remains are several graveyards dating from 1st century AD found in the central Žumberak Mountains, in villages of Gornja Vas and Bratelji. People buried in those graveyards belonged to the Celtic tribe of Latobics. Many glass containers were found in these graves. These containers were produced in northern Italy, and they are proof that people in the Žumberak Mountains had a powerful economy at that time.[11]

After the decline of the Roman Empire, numerous Germanic and Slavic tribes passed across the Pannonian Plain. Almost nothing is known when the Croats came to the Žumberak Mountains. The earliest written texts and archaeological finds enlighten the history of the Žumberak Mountains from the 12th century on. At that time the Žumberak Mountains were the border between the Croatian-Hungarian Kingdom and the Holy Roman Empire.[12]

Colonization of Žumberak with Vlachs and Uskoks begins 1526.[13]

The isolated region on the Croatian side has always had a low population. In 1530, the immigration of Uskoks started, which lasted until the 17th century, which brought a large population of Štokavian speakers to the region. The Uskoks in this area were led by the Delišimunović family who were counts in Kostanjevac. The Žumberak Mountains were then part of Austrian Military Frontier, created by the Habsburgs to serve as a defensive buffer between their empire and the Ottoman Empire. Uskoks from this area, were the only military personnel on the Military frontier, that weren't living close to the border itself, the Žumberak Mountains themselves were an enclave within Banovina and did not directly border the Ottoman Empire, so they had to walk for half a day or longer to their posts in Ogulin, Cazin, Bihać etc. 500 Uskoks from the Žumberak Mountains fought in the Battle of Sisak. They had huge losses for their standard, losing 40 soldiers in crucial mission of taking over the bridge over Odra river.[14][15] In the year 1545. they were called by citizens of Zagreb, to defend the city from the Ottomans because the regular army under the leadership of Croatian Ban was heavily defeated in Hrvatsko Zagorje. As we know Zagreb was never occupied by the Ottomans.[12]

Because of the immigration of Uskoks, the region is the intersection of all three Croatian dialects. The descendants of Uskoks who are Štokavian speakers are the majority in the Žumberak Mountains.

Mass emigrations started in the 19th century, when Military frontier was disestablished. People in the Žumberak Mountains were no longer needed in the army. Since army salaries, which were main source of wealth, were not coming any more to the Žumberak Mountains. This was the main reason why people fell to poverty and started immigrating to the United States.

World War II in Yugoslavia began on 6 April 1941 with the invasion by Nazi Germany. Soon after that, the Croatian part of the Žumberak Mountains became a part of the Independent State of Croatia (NDH), a World War II puppet state of Nazi Germany and Italy, with the western part being directly occupied by Italy. The Slovenian part was annexed directly to the Third Reich. The resistance movement in the Žumberak Mountains began when Partisans from 1st Zagreb Partisan Detachment came to this area. Matija Gubec Partisan detachment was established here in August 1941, However it was quickly destroyed. In 1942 partisans from Kordun managed to attract local people to join the resistance, so in 1942 Žumberak-Pokuplje partisan detachment was established. Later they merged with First Croatian proleterian battalion in famous XIII. proletarian brigade Rade Končar. That brigade managed to liberate Krašić in January 1943, which was a great victory for Partisan movement, since North-West Croatia was considered to be NDH stronghold. Many villages were completely burned and destroyed by the fascists, because their inhabitants allegedly helped the partisans. Žumberak was finally liberated on 9 May 1945, by the 10th division of Yugoslav People's Army.

The Žumberak Mountains are the site of the Jazovka Pit, location of a World War II massacre of retreating Ustasha soldiers and civilians mostly from hospitals in Zagreb by the communists, not partisans from Žumberak-Pokuplje partisan detachment, or local people.[16]

In the nineteen-sixties and nineteen-seventies, the second mass emigration started, mostly to Germany. Žumberak-Gorjanci memorial area was established in 1971.

In 1991 area of the Žumberak Mountains became a part of independent Croatia and Slovenia. A military complex near the top of Trdina Peak, created by the Yugoslav People's Army, has been a subject of a dispute between the two new countries since the 1990s because it is held by the Slovenian army, but the complex is actually located on Croatian soil. Escalation was prevented due to amicable diplomacy.

Both, Slovenia, and Croatia, are members of the European Union, and it is expected that Croatia will soon join Schengen area, so there will be no actual border in the Žumberak Mountains.
