Orestis (region) in the context of "Upper Macedonia"

The Dassaretii (Ancient Greek: Δασσαρῆται, Δασσαρήτιοι, Dassaretai, Dassaretioi; Latin: Dassaretae, Dassaretii) were an Illyrian people that lived in the inlands of southern Illyria, between present-day south-eastern Albania and south-western North Macedonia. Their territory included the entire region between the rivers Asamus and Eordaicus (whose union forms the Apsus), the plateau of Korça locked by the fortress of Pelion and, towards the north it extended to Lake Lychnidus up to the Black Drin. They were directly in contact with the regions of Orestis and Lynkestis of Upper Macedonia. Their chief city was Lychnidos, located on the edge of the lake of the same name. One of the most important settlements in their territory was established at Selcë e Poshtme near the western shore of Lake Lychnidus, where the Illyrian Royal Tombs were built.

The Dassaretii were one of the most prominent peoples of southern Illyria, forming an ethnic state. They made up the ancient Illyrian kingdom that was established in this region. The weakening of the kingdom of the Enchelei presumably led to Enchelei's assimilation and inclusion into a newly established Illyrian realm at the latest in the 6th–5th centuries BC, marking the arising of the Dassaretii, who appear to have replaced the Enchelei in the lakeland area.

Pausanias of Orestis (Ancient Greek: Παυσανίας ἐκ τῆς Ὀρεστίδος) was a member of Philip II of Macedon's personal bodyguard (somatophylakes). He assassinated Philip in 336 BC. Pausanias was killed while fleeing the assassination.

Craterus, also spelled Krateros (Greek: Κρατερός; c. 370 BC – 321 BC), was a Macedonian general under Alexander the Great and one of the Diadochi. Throughout his life, he was a loyal supporter of Alexander the Great.

Craterus was the son of a Macedonian nobleman named Alexander from Orestis and brother of admiral Amphoterus. Craterus commanded the phalanx and all infantry on the left wing in Battle of Issus in 333 BC. In Hyrcania, he was sent on a mission against the Tapurians, his first independent command with the Macedonian army. At the Battle of the Hydaspes in 326 BC, near modern Jhelum, he commanded the rearguard, which stayed on the western bank; his men crossed the river only during the final stages of the battle.

Elimiotis or Elimeia (Ancient Greek: Ἐλιμιῶτις or Ἐλιμία or Ἐλίμεια) was a region of Upper Macedonia that was located along the Haliacmon river. The capital of Elimiotis was Aiani, located in the modern municipality of Kozani, Western Macedonia. It was bordered by Orestis and Eordaea in the north, Pieria in the east, Perrhaebia/Thessaly in the south, and Tymphaea and Parauaea in the west, and was inhabited by the Epirote Greek tribe of Elimiotes or Elimiotae (Ancient Greek: Ἐλιμιῶται). In earlier times, it was independent and the Derdas family ruled the local kingdom from its capital Aiane. However, later it lost its independence and by 355 BC, Elimiotis was part of the kingdom of Macedon.

Eordaea (also spelled Eordaia or Eordia, Greek: Ἐορδαία) was a geographical region of Upper Macedonia and later an administrative region of the kingdom of Macedon. Eordaea was located south of Lynkestis, west of Emathia, north of Elimiotis, and east of Orestis. It was incorporated into the Argead kingdom of Macedon earlier than the rest of Upper Macedonia.

Eordaea stretched in the basin of Eordaia, the current homonymous municipality in Greece, which is named after the ancient region, and also in the southern part of the municipality of Amyntaio and the western part of the municipality of Edessa.
