As a part of the 2011 Kallikratis government reform, the regional unit of Pella was created out of the formerprefecture Pella (Greek:Νομός Πέλλας). The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganised, according to the table below.[3]
The regional unit covers an area of 2,505.8 square kilometres (967+1⁄2 sq mi), the majority of which is covered by arable land, forests and pastures. Mountainous areas surrounding Pella are theVoras Mountains (withKaimaktsalan reaching a height of 2,524m),Mount Vermion (2,027m),Mount Paiko (1,458m),Mount Tzenna (2,182m) andMount Pinovo (2,154m). The main plains are Pozar in the north and the vast plain ofGiannitsà in the southeastern part. Other natural features of the area include LakesVegoritida and Agra, and RiversLoudias and Edessian. Pella's southernmost portion is flat and in ancient times, it was a gulf connected to theAegean Sea. The elevation in the south does not exceed about 5 to 10 m (16 to 33 ft) above sea level. Pella has surface and groundwater resources. There are a number of archaeological sites in the area.
Pella borders the regional units ofKilkis to the northeast,Thessaloniki to the east,Imathia to the south,Kozani to the southwest, by Lake Vegoritida to the southwest, and byFlorina to the west. To the north, it is bounded by the national border between Greece andNorth Macedonia.
In antiquity, the area around the modern Pella regional unit was part of the ancient GreekKingdom of Macedon. It later became part of theRoman Empire and later theByzantine and theOttoman Empires. Following approximately 500 years of Ottoman rule, it rejoinedGreece in 1913, following theBalkan Wars.
