Strmen is a village in central Croatia, in the municipality of Sunja, Sisak-Moslavina County. It is located in the Banija region.
The village of Strmen was established in the late 17th century by the Orthodox Serb settlers from Podkozarje area in Bosnia.[2] The village became a part of the Military Frontier which, at the time, was expanding onto former Ottoman territories such as Lika, Kordun, Banija and lower Slavonia.
During the World War II, the village was a part of the Nazi-puppet state, the Independent State of Croatia, in the municipality of Crkveni Bok, which comprised the villages of Crkveni Bok, Strmen and Ivanjski Bok. Already in early autumn of 1941, the villages' population was subjected to conversion to the Roman Catholic faith.[3]
The three villages, often referred to as the "Banija Triangle", suffered heavy demographic losses with nearly 30% of its population perishing in the World War II.
According to the 2011 census, the village of Strmen has 135 inhabitants. This represents 37.92% of its pre-war population.According to the 1991 census,[4] 92.42% of the village population were ethnic Serbs (329/356).
