Lower Navarre (,
Gascon/Bearnese:
Navarra Baisha, , ) is a traditional region of the present day
Pyrénées Atlantiques département of
France. It corresponds to the northernmost
merindad of the
Kingdom of Navarre during the
Middle Ages. After the
Spanish conquest of Iberian Navarre (1512–24), this
merindad was restored to the rule of the native king,
Henry II. Its capitals were
Saint-Jean-Pied-de-Port and
Saint-Palais. In the extreme north there was the little sovereign
Principality of Bidache. Its extent is of 1,284 km
2, and has a decreasing population of 44,450 (in 1901), 25,356 (in 1990).
