History of the region 
||This section needs additional citations for verification. (March 2008)|
The isolated region on 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. Žumberak was then part of Austrian Military Frontier, created by the Habsburgs to serve as a defensive buffer between their empire and the Ottoman Empire. Žumberak itself was an enclave within Banovina and did not directly border the Ottoman Empire. The mountain is called Uskokengebirge or Sichelberg in German.
The region is today the intersection of all three Croatian dialects. The descendants of Uskoks who are Štokavian speakers are majority in Žumberak. Today there are more Greek Catholic churches in Žumberak than Latin Catholic churches (approx. 2 to 1).
A military complex near the top of Trdinov vrh, created by the Yugoslav People's Army, has been a subject of a dispute between the two new countries since the 1990s. Escalation was prevented due to amicable diplomacy.
The population of about 3,000 people (on the Croatian side) consists mainly of the elderly.
