Provinces · The later eastern provinces
LE-48 Palaestina Tertia / Salutaris

The province combined cities, cultivated arid-zone settlements, pastoral communities, and routes towards the Red Sea and Sinai. Water management, farming, livestock, trade, garrisons, churches, and monasteries all contributed to its society. It was not simply an empty desert surrounding Petra.
The reassignment of Petra demonstrates why a city’s provincial affiliation must be dated. Christian institutions developed strongly in several southern settlements. Later warfare and conquest altered the political framework, while environmental, economic, and local security conditions affected communities differently. The names Tertia and Salutaris describe administrative stages and usages within this late southern jurisdiction.
