It is not possible to observe the chronology of Mokra Gora and it surroundings from the time of the first settling of the Slavs due to the lack of material proofs. These were destroyed in the vortex of wars frequent in this restless Balkan region.

It is certainly known that important roads passed across Šargan and the valley of Mokra Gora towards the neighbouring Višegrad, Priboj, and Nova Varoš during the period of formation and strengthening of the medieval Serbian state under the House of Nemanjić. The oldest material evidence on the existence of the settlement Mokra Gora is preserved at the old cemetery. The tombstones prove that the village has been inhabited since the 14^th century, during the reign of Tsar Dušan. After hid death, Vojislav Vojinović became the master of this region, and afterwards, Nikola Altomanović established a state "from Rudnik to Dubrovnik". From 1374 until the battle of Kosovo, Prince Lazar ruled this area as well as the area of Dobrun. In 1459, Turkish invaders arrived and established a boundary between the sanjaks of Smederevo and Bosnia across Šargan. After the long period of slavery, the revolutionary uprisings of the Serbian people caused the Turkish boundary to be shifted in 1834 from Šargan to Balvan. During this period, convoys of refugees from Montenegro and Bosnia crossed the boundary lines in Mokra Gora and Javor, seeking rescue from Turkish oppression. Adversities of the people in this region were continued during the Serbian-Turkish war in 1876, the annexation of Bosnia and Herzegovina in 1908, the Balkan wars in 1912, and later on, the World Wars.

Constant historical turmoil, as well as settling of refugees and immigrants, influenced the frequent changes in demography of this region. Present inhabitants of the valleys of Mokra Gora and Kremna are mostly descendants of the immigrants that settled during the 17^th, 18^th, and 19^th century, coming from Herzegovina, Bosnia, Montenegro, and the district of Moravička. In the 20^th century, the immigrants, most of them from Lika and Kordun, were associated with the construction of the Šargan railway. However, along with the immigration process, the emigration for the purpose of education or employment also took place and therefore the number of inhabitants was halved during the last fifty years. According to the last census from 2002, only 605 inhabitants live in the village of Mokra Gora.

In keeping with the natural environment, the villagers lived in a traditional way during the past, from forestry and agriculture, mainly cattle breeding. Timber, kindling wood, tar, meat, milk, leather, wool, plums, corn, honey, wax, brandy, and hemp or linen fabric were the products of this region. Although the modern way of living is much different, a large number of households kept some form of the old activities.
