It is known that El Pallars was inhabited since prehistory, from 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 the Aran Valley, although recent archaeological finds begin to indicate the opposite.
Already in medieval times and after the dismantling of the Roman world, it was the mountain communities that exploited their natural resources.
At the time of the Muslim invasions, the territory was subjected to little more than the payment of tributes or land taxes.
After the conquest and domination of the counts of Tolosa, the county house of Pallars began, which would be the oldest of all the Catalan counties and would end in 1487 with the fall of the castle of València d'Àneu and the end of Hug Roger III's rule.
The general crisis of the feudal order has its continuity in the modern age and in the transformation of the Pallarés county into a marquisate in the hands of the Cardona family. This marquisate coexisted with various manors, but together they formed part of a superior, royal structure, which would be the sotsvegueria de Pallars and which in the 18th century would become the corregimiento of Talarn.
From the end of the 18th century until 1870, the population grew until it reached its demographic peak of 20,348 inhabitants in 1860.
From 1870 to 1910 there is a crisis of the subsistence economy, which until then had prevailed and a demographic and economic decline begins due to the civil confiscation of Madoz, the bad weather and the arrival of the "fil loxera". ", among other.
From 1910 to 1960 , and due to the implantation of hydroelectric plants, a process of modernization of traditional society began, cut short by the civil war and the postwar 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 Pallars to a new demographic decline to the point of losing half of the population (5,247 inhabitants).
