How did the lands of canaan and judea change to Palestine im genuinely curiosity ?
The name Palestine is the most commonly used from the Late Bronze Age (from 1300 BC) onwards. The name is evident in countless histories, ‘Abbasid inscriptions from the province of Jund Filastin (Elad 1992), Islamic numismatic evidence maps (including ‘world maps’ beginning with Classical Antiquity) and Philistine coins from the Iron Age and Antiquity, vast quantities of Umayyad and Abbasid Palestine coins bearing the mint name of Filastin. The manuscripts of medieval al‑Fustat (old Cairo) Genizah also referred to the Arab Muslim province of Filastin (Gil 1996: 28‒29). From the Late Bronze Age onwards, the names used for the region, such as Djahi, Retenu and Cana’an, all gave way to the name Palestine. Throughout Classical and Late Antiquity – a term used by historians to describe a period between the 3rd and 8th centuries AD, a transitional period from Classical Antiquity to the Middle Ages in the Mediterranean world, Europe and the Near East – the name Palestine remained the most common. Furthermore, in the course of the Roman, Byzantine and Islamic periods the conception and political geography of Palestine acquired official administrative status.
