It is known that Pallars was populated since prehistoric times, of which numerous testimonies have come down to us in the form of megalithic monuments.
It seems that the Roman presence was not very intense, unlike in the Aran Valley, although recent archaeological finds are beginning to indicate the opposite.
Already in the medieval period, and after the disintegration of the Roman world, it was the mountain communities that exploited natural resources.
In the times of the Muslim invasions, the territory was subjected to little more than the payment of tributes or territorial taxes.
After the conquest and rule of the Counts of Toulouse, the Count's House of Pallars began, which would be the longest-lived of all the Catalan counties and would end in 1487 with the fall of the castle of València d'Àneu and the end of the rule of Hugh Roger III.
The general crisis of the feudal order continued into the modern age and in the transformation of the Pallars county into a marquisate in the hands of the Cardona family. This marquisate coexisted with several lordships, but they all formed part of a superior, royal structure, which would be the sotsvegueria of Pallars and which in the 18th century would become the corregiment of Talarn.
From the end of the 18th century until 1870, the population grew until reaching a demographic peak of 20,348 inhabitants in 1860.
From 1870 until 1910, there was a crisis in the subsistence economy, which had prevailed until then, and a demographic and economic decline began due to the civil confiscation of Madoz, bad weather and the arrival of phylloxera, among others.
From 1910 to 1960, and due to the implementation of hydroelectric power plants, a process of modernization of traditional society began, truncated by the Civil War and the post-war period.
From 1960 to 1980, the region suffered a second crisis caused by the mechanization of the countryside and the industrialization of the cities, which led to a new demographic decline in Pallars to the point of losing half of its population (5,247 inhabitants).
