Almopia (), or Enotia (Greek: ÃÂýÃÂÃÂïñ), also known in the Middle Ages as Moglena (Greek: ÃÂÿóûõýì, Macedonian and Bulgarian: ÃÂõóûõý or ÃÂÃÂóûõý), is a municipality and a former province (õÃÂñÃÂÃÂïñ) of the Pella regional unit in Macedonia, Greece. The seat of the municipality is the town Aridaia. The municipality has an area of 985.817 km<sup>2</sup>.
The name Almopia (, Almà Âpia) derives from the Almopes (), a Paeonian tribe that originally inhabited the area before being expelled from the region during the reign of Alexander I (r. 498âÂÂ454 BC) when Almopia was incorporated into the ancient Macedonian kingdom. The Almopes traced their descent to the eponymous mythological figure of Almops, son of the Greek God Poseidon and Helle. The 2nd-century astronomer and geographer Claudius Ptolemy records three cities in the region in his Geography: Horma (), Europos () and Apsalos ().
In the early Byzantine period, the area was renamed to Enotia (Greek: ÃÂýÃÂÃÂïñ) after a nearby fortress, probably in the vicinity of modern Notia. The name was revived between 1915 and 1927 for the Greek province as well.
In the later Middle Ages, the area was known as Moglena (Greek: ÃÂÿóûõýì, , ), from the Slavic word for "fog". Until the early 11th century, Moglena was a province of the First Bulgarian Empire. Captured by the Byzantine emperor Basil II in 1015, it is attested as the seat of a bishopric in 1020, and as capital of its own theme in 1086. The area remained under Byzantine rule until the aftermath of the Fourth Crusade, when it was captured by Tsar Kaloyan of the Second Bulgarian Empire. It was incorporate in the Serbian Empire by Stefan Duà ¡an in 1346. Moglena was inhabited mainly by Megleno-Romanians and Slavic people. In Ottoman times, the region was also known by its Turkish name Karacova or Karadjova valley ("Black Valley", Greek: ÃÂñÃÂñÃÂöÃÂòñ) or in Ottoman Turkish: ÃÂçñçìçÃÂç.
Until the Greco-Turkish War (1919âÂÂ1922) and the population exchange between Greece and Turkey in 1924, Muslim Pomaks and Megleno-Romanians made up part of the population.
The municipality Almopia was formed at the 2011 local government reform by the merger of the following 2 former municipalities, that became municipal units:
The province of Almopia (ÃÂÃÂñÃÂÃÂïñ ÃÂûüÃÂÃÂïñÃÂ) was one of the three provinces of Pella Prefecture. Its territory corresponded with that of the current municipality of Almopia. It was abolished in 2006.
