Originally part of the possessions of the Counts of Alt-Homburg during the Middle Ages, it gradually came under the control of Basel from 1400 to 1534. Due to its location near the former border with Austria, it served as a customs point until 1801. Following the canton division conflicts from 1831 to 1833, Anwil aligned with Basel before ultimately becoming part of Basel-Landschaft. More details can be found on its Wikipedia page.
