In 1479, the Lord of Béarn, Francis Phoebus, inherited the Kingdom of Navarre, across the Pyrenees to the southwest. The two sovereign entities would from then on remain in personal union. In 1512, the Kingdom of Navarre was almost entirely occupied by Spain; only Lower Navarre, north of the Pyrenees, escaped Spanish permanent occupation. In 1517, Henry I (II of Navarre) inherited it, as well as Béarn, from his mother. The Bearnese monarchs extended the use of Occitan to Navarre after 1512, despite the fact that it was not the vernacular language there, where Basque was the tongue of the people. The Estates of Navarre convoked in 1522 (or in 1523, according to other sources) kept records in Occitan, as did the Chancery of Navarre created in 1524. When Henry II revised the "Fueros" of Navarre in 1530, he had them translated from Castilian into Occitan.
