In German the commune name is Aßweiler.

Asswiller was a small lordship dependent on the Counts of La Petite-Pierre. When the count palatine of Bavaria, Georg Johann I of Bavaria, took possession of the county, he granted Asswiller as a hereditary fief to the Dalheim family (1588), who were soon succeeded by the Steinkallenfels family: senior officials of the palatine counts. These Protestant lords introduced the Reformation and remained in Asswiller from the 16th century to 1819.^[5] In 1789 Asswiller belonged to the Lord of Carbiston who had acquired it in 1771 by marriage with the heiress of the Steincallenfels family.

After the French Revolution Asswiller was attached to France in 1793 by decree of the National Convention, which overrode the rights of princes holding possessions.
