By inheritance from the aforementioned Heredia, the domain of the place passed to the dukes of Solferino at the beginning of the 18th century, who maintained it until the abolition of the lordships.

Alcarràs also suffered the War of Succession, but in 1721 it had partially recovered and constituted a town hall (since 1500 a small municipal council had been run with three jurats or paers).

In the 18th century, coinciding with a notable demographic increase, the great church was built and the nucleus extended along the Madrid road (1777), the current Raval de Lleida.

In the Peninsular War, the residents of Alcarràs became sometent and fought under the orders of Colonel Baget in the Sierra de Alcubierre and the Bruc.

In 1840, with the constitutional town hall, schools were created and in the summer of 1896 the spa of Alcarràs appeared, with ferruginous sodium chloride waters, good for skin diseases until the doors closed in 1920.

During the Catalan Referendum for the Independence on 1 October 2017, Alcarràs was one of the populations where the Spanish police beat the citizens in order to impede the voting.
