The first traces of civilisation in the commune date to Prehistory or more precisely to the Magdalenian period.
Excavations in four caves in the commune (Maladore, Poeymaü, Saint-Michel, and Espalungue) uncovered bones, tools, and many snail shells.

The village of Eruri or Aruri was mentioned at the beginning of the 13th century.
It was from the beginning of that time that the Ossau Union was created which permitted relative independence for the communes in the valley until the French Revolution.

Paul Raymond noted on page 14 of his 1863 dictionary that the commune had a Lay Abbey, vassal of the Viscounts of Béarn, with 86 fires and depended on the bailiwick of Ossau.

It was in the 19th century that economic growth started in the commune.
Sawmills and Marble quarries were created which provided a living to several hundred people.
One quarry still operates today.

On 29 February 1980 Arudy was the epicentre of an earthquake measuring 5.2 on the Richter scale and 7.5  on the MSK scale which damaged many buildings in the town.
The college had to be rebuilt.
