Harran
Osroene

Osroene, also spelled Osroëne and Osrhoene and sometimes known by the name of its capital city, Edessa, was a historical kingdom in Upper Mesopotamia, which was ruled by the Abgarid dynasty of Arab origin. Generally allied with the Parthians, the Kingdom of Osroene enjoyed semi-autonomy to complete independence from the years of 132 BC to AD 214. Though ruled by a dynasty of Arab origin, the kingdom's population was mainly Aramean with a Greek and Parthian admixture. In addition, though Arab cults were attested at Edessa, the city's cultural setting was fundamentally Aramaic alongside strong Parthian influences.
Assur

Aššur, also known as Ashur and Qal'at Sherqat, was the capital of the Old Assyrian Empire, the Middle Assyrian Empire, and for a time, of the Neo-Assyrian Empire. The remains of the city lie on the western bank of the Tigris River, north of the confluence with its tributary, the Little Zab, in what is now Iraq, more precisely in the al-Shirqat District of the Saladin Governorate.
Adiabene

Adiabene was an ancient kingdom in Assyria, with its capital at Arbela.
Upper Mesopotamia

Upper Mesopotamia is the name used for the uplands and great outwash plain of northwestern Iraq, northeastern Syria and southeastern Turkey, in the northern Middle East. Since the early Muslim conquests of the mid-7th century, the region has been known by the traditional Arabic name of al-Jazira and the Syriac (Aramaic) variant Gāzartā or Gozarto (ܓܙܪܬܐ). The Euphrates and Tigris rivers transform Mesopotamia into almost an island, as they are joined together at the Shatt al-Arab in the Basra Governorate of Iraq, and their sources in eastern Turkey are in close proximity.
Osroes I

Osroes I or Chosroes Parthian: 𐭇𐭅𐭎𐭓𐭅 (Husrōw) was a prince of Iranian and Greek ancestry. He ruled the Parthian Empire from 109 to 129, with a brief interruption from 116 to 117. He succeeded his brother Pacorus II. For the whole of his reign he contended with the rival King Vologases III based in the East of Parthia.
Kitos War

The Kitos War was one of the major Jewish–Roman wars, 66–136. The rebellions erupted in the year 115, when a majority of the Roman armies were fighting Trajan's Parthian War on the eastern border of the Roman Empire. Major uprisings by ethnic Judeans in Cyrenaica, Cyprus and Egypt spiraled out of control, resulting in a widespread slaughter of left-behind Roman garrisons and Roman citizens by Jewish rebels.
Seleucia

Corduene

Corduene was an ancient region located in south of Lake Van, present-day eastern Turkey.
Mesopotamia (Roman province)

Mesopotamia was the name of two distinct Roman provinces, the one a short-lived creation of the Roman Emperor Trajan in 116–117 and the other established by Emperor Septimius Severus in ca. 198, which ranged between the Roman and the Sassanid empires, until the Muslim conquests of the 7th century.
Asoristan

Asoristan was the name of the Sasanian province of Assyria and Babylonia from 226 to 637.
Achaemenid Assyria

Athura, also called Assyria, was a geographical area within the Achaemenid Empire in Upper Mesopotamia from 539 to 330 BC as a military protectorate state. Although sometimes regarded as a satrapy, Achaemenid royal inscriptions list it as a dahyu, a concept generally interpreted as meaning either a group of people or both a country and its people, without any administrative implication.
Roman Armenia

Roman Armenia refers to the rule of parts of Greater Armenia by the Roman Empire, from the 1st century AD to the end of Late Antiquity. While Armenia Minor had become a client state and incorporated into the Roman Empire proper during the 1st century AD, Greater Armenia remained an independent kingdom under the Arsacid dynasty. Throughout this period, Armenia remained a bone of contention between Rome and the Parthian Empire, as well as the Sasanian Empire that succeeded the latter, and the casus belli for several of the Roman–Persian Wars. Only in 114–118 was Emperor Trajan able to conquer and incorporate it as a short-lived province.
Singara

Singara was a strongly fortified post at the northern extremity of Mesopotamia, which for a while, as it appears from coins found, was occupied by the Romans as an advanced colony against the Persians. It was the camp of legio I Parthica.
Trajan's Parthian campaign

Trajan's Parthian campaign, also known as Trajan's Parthian War, was engaged by Roman emperor Trajan in the year 115 against the Parthian Empire in Mesopotamia. The war was initially successful for the Romans, but due to a series of setbacks, including wide-scale rebellions in the Eastern Mediterranean and North Africa, as well as Trajan's death in 117, ended in a Roman withdrawal.
