Hasankeyf is a town located along the Tigris, in the Hasankeyf District, Batman Province, Turkey. It was declared a natural conservation area by Turkey in 1981.
Despite local and international objections, the city and its archaeological sites have been flooded as part of the Ilısu Dam project. By 1 April 2020, water levels reached an elevation of 498.2 meters, covering the whole town.
The town had a population of 4,329 in 2021.
Toponymy Hasankeyf was an ancient settlement that has borne many names from a variety of cultures during its history. The variety of these names is compounded by the many ways that non-Latin alphabets such as Syriac and Arabic can be transliterated. Underlying these many names is much continuity between cultures in the basic identification of the site.
The city of Ilānṣurā mentioned in the Akkadian and Northwest Semitic texts of the Mari Tablets (1800–1750 BC) may possibly be Hasankeyf, although other sites have also been proposed. By the Roman period, the fortified town was known in Latin as Cephe, Cepha or Ciphas, a name that appears to derive from the Syriac word ܟܐܦܐ (kefa or kifo), meaning "rock". As the eastern and western portions of the Roman Empire split around AD 330, Κιφας (Kiphas) became formalized as the Greek name for this Byzantine bishopric.
Following the Arab conquest of 640, the town became known under the Arabic name (Ḥiṣn Kayfa). "Hisn" means "fortress" in Arabic, so the name overall means "rock fortress". Western reports about the town before the 20th century refer to it by various names that are transliterated from Arabic or Ottoman Turkish. The most popular of these were Hisn Kaifa and Hisn Kayfa, although a wide variety of others are used including Ḥiṣn Kaifā, Ḥiṣn Kayfā, Ḥiṣn Kayfâ, Ḥiṣn Kīfā, Ḥiṣn Kîfâ, Hisn Kayf, Husn Kayfa, Hassan-Keyf, Hosnkeif and Husunkeïf. Two early Armenian historians list additional names for the town: Harsenkev () is recorded by Matthew of Edessa (Mesrob Eretz) and Kentzy is recorded by P. Lucas Ingigian.
As part of Atatürk's Reforms in the 1920s and '30s, many place names were modified to more Turkish-sounding forms and the town's official name was changed to Hasankeyf. This version appears occasionally in foreign reports in the mid 20th-century but only becomes prevalent after about 1980.
History
Middle Bronze Age (Ilānṣurā?) During the Middle Bronze Age the area around Hasankeyf was likely part of the Hurrian kingdoms. The Akkadian and Northwest Semitic texts of the Mari Tablets (1800–1750 BC) refer to Ilānṣurā, an important walled city on a large river. Ilānṣurā has been tentatively identified with Hasankeyf, although several locations in northeast Syria have also been proposed.
Late Bronze Age By the 14th century BC, the Hasankeyf area was within the Hurrian kingdom of Mitanni. Between the 9th and 7th centuries BC it was part of the Neo-Assyrian Empire, and by the mid-6th century it was part of the Median empire.
Roman and Byzantine empires In Roman Empire times, Hasankeyf (known as Kepha, Cephe, Cepha or Ciphas) was a base for legionaries on the frontier with the Sasanian Empire of Persia.
For a time the town became the capital of the Roman province of Arzanene, although Nisibis was the headquarters of the Dux Mesopotamiae. Constantius II (324–361) built a fort at Kepha, but it is unclear whether this was on the current citadel site. The existence of a Roman bridge across the Tigris at Hasankeyf has been viewed as "highly probable" by one scholar who speculates that (like the later bridge) it may have had "a wooden superstructure based on piers of masonry and natural stone". However, none of the remaining structure of the bridge appears to date from Roman times.
The balance of power in the region shifted significantly in 363. Following the death of the emperor Julian at the Battle of Samarra, his successor Jovian was forced to surrender to the Persian King Shapur II the eastern provinces of Arzanene, Moxoene, Zabdicene, Corduene and Rehimene. This included 15 castles, along with the cities of Singara and Nisibis, but not their inhabitants, and the fortress of Castra Maurorum. While Kiphas had been administered as part of Arzanene up to 363, it lay on the south bank of the Tigris and was not surrendered to the Sasanians. Before the treaty, the fort at Kiphas had been on the border between Roman territory and the Armenian vassal kingdom of Arzanene. Now the border with Persia ran along the Tigris and the legionnaires at Kiphas were stationed right on it. Their role was chiefly to protect the Tur Abdin massif and the approach through it to the Roman province of Sophanene from attack by the Persians in Arzanene.
Recording the situation at the end of the fourth century, the Notitia Dignitatum identifies Cepha as the seat of the commander of the Legio II Parthica. The bishop of Cepha is recorded as attending the Council of Chalcedon in October 451, which implies the settlement must have become a sizeable town by that time. As the use of Latin began to wane in the Eastern Roman Empire, Κιφας (Kiphas) became formalized as the Greek name for the Byzantine bishopric.
Rescue excavations from 2005 to 2008 uncovered evidence of the base of a Roman gateway to the upper city, a row of shops from the late Roman period, and Roman floor and wall mosaics.
By the sixth century, the Persians were mounting frequent attacks on the eastern border of the Byzantine empire. As a consequence, the Byzantines built a great number of military installations in the region during the early and mid-sixth century. Despite this the Persians seized the opportunity of a Byzantine civil war to attack the eastern provinces, in what became the Byzantine–Sasanian War of 602–628. Early in the conflict they occupied Kiphas along with Mardin, Dara and probably the rest of the Tur Abdin, and these were held for most of the rest of the war. The treaty that concluded the war restored Kiphas to Byzantine control, but the gain was to prove short-lived. Writing between about 600 and 610, the Byzantine geographer George of Cyprus mentions Cepha as a fortress in the Mesopotamia section of his Descriptio Orbis Romani.
Muslim conquest By the 630s, Muslim Arab forces had conquered large parts of Mesopotamia, Syria and Iran. Kiphas appears most likely to have been captured during the Muslim conquest of Armenia in 640, shortly after the conquest of Nisibis. An account from this period provides the earliest mention of any bridge across the Tigris at this site.
Over the subsequent five centuries, the town was ruled by Arab dynasties under the name Hisn Kayfa, first by the Umayyad and Abbasid caliphates and later by semi-autonomous Hamdanid and Marwanid rulers.
Fatima, the Kurdish mother of the Hamdanid ruler Abu Taghlib,Canard (1965) took control of the town in c. 900 A.D.
Artuqid period (1102–1232) In the 11th century, Seljuk Turks and their Turkmen and Oghuz allies moved into Western Armenia, culminating in the Seljuk defeat of Byzantine forces at the Battle of Manzikert in 1071. Victory at Manzikert quickly resulted in Seljuk forces controlling large parts of Anatolia and northern Mesopotamia. The Seljuk sultan Barkiyāruq granted Hisn Kayfa as a iqtâ to the Artuqids in 1101/1102.
In 1104, Joscelin I of Edessa, at that time the count of Turbessel, was imprisoned at Hisn Kayfa by Sökmen after he was captured at the Battle of Harran along with his kinsman Baldwin II of Jerusalem, then count of Edessa. Baldwin was imprisoned at Mosul by the Seljuk atabeg Jikirmish. After the death of Jikirmish in 1107 and the payment of a significant ransom, Baldwin II and Joscelin I were released. Coincidentally, both men later became prisoners of Belek Ghazi in 1122/1123.
Control of trade along the Diyarbakır–Mosul road paralleling the Tigris, and north–south between Lake Van and the Euphrates generated prosperity for the Artuqids and ensured their power in the region. Consequently, the existence of a reliable river crossing for goods and people was a priority, and the Artuqids built a bridge across the Tigris at some time between 1147 and 1172.
This period was something of a golden age for Hisn Kayfa, with the Artuqids and their successors, the Ayyubids, building the Small Palace and the Great Palace as well as the Tigris bridge. The infrastructure, location and significance of the city helped increase trade and made Hisn Kayfa a staging post on the Silk Road.
In April 1204, the Artuqid emir al-Salih Mahmud, who controlled both Amida and Hisn Kayfa, joined with al-Ashraf, the Ayyubid ruler of Harran, and princes from Mayafaraqin, Cizre, Sinjar and Irbil to rout the army of Nur ad-Din Arslan Shah I, the Zengid ruler of Mosul, in a battle near Nusaybin. In the second half of 1204/1205, al-Salih Mahmud also lent his forces to help al-Ashraf attack Harput, which was controlled by another branch of the Artuqids.
By 1229/1230, al-Salih's successor, Rukn al-Din Madud, was allied with the Khwarazmshah Jalal al-Din Mangburni against the Ayyubid rulers al-Ashraf and al-Kamil.
By 1232, control of Amida and Hisn Kayfa had passed to the Artuqid prince al-Masʿud. Troubled by the alliance with Khwarazm, al-Ashraf and al-Kamil resolved to attack Amida, and used as a pretext reports of al-Masʿud's misrule, including his abuse of local women. The combined Ayyubid armies, swelled by contributions from many of their vassals, besieged Amida on October 1232. By 18 October 1232, al-Masʿud surrendered Amida to al-Kamil. Al-Kamil then sent his brother, al-Ashraf, along with al-Muzaffar Ghazi of Mayafaraqin to Hisn Kayfa to obtain its surrender. Even though, the Ayyubid force had brought with them al-Masʿud as a captive, the garrison at Hisn Kayfa resisted for some time, and the city was captured only in Safar 630/November 1232.
Ayyubids and Mongols (1232–1462)
Once the citadel fell to the Ayyubid forces, al-Kamil immediately installed his 27-year-old son, as-Salih Ayyub, as governor of both Amida and Hisn Kayfa, beginning the period of Ayyubid rule over the Diyar Bakr.
Ayyubid rule of Hisn Kayfa was insecure almost from the start. During 1235, the Rum Seljuk forces of 'Alā ad-Dīn Kayqubād had advanced into Southeast Anatolia, capturing Harput, Urfa and Harran. In Dhu-l-Hijja 632/August 1235, they laid siege to Amida, but were unsuccessful in capturing the city and consequently did not advance as far as Hisn Kayfa.
Only five years after Hisn Kayfa was captured by the Ayyubids, it had already become a pawn in the dynasty's power struggles. By al-Ashraf had become resentful of his brother al-Kamil's ill-concealed ambition. al-Ashraf recruited the rulers of Aleppo and Homs to his faction and sent ambassadors to the court of Rum Seljuk sultan 'Alā ad-Dīn Kayqubād to propose an alliance. When they arrived at the Seljuk court they discovered that Kayqubād had died on 4 Shawwal 634/31 May 1237, and they now had to deal with his son, Ghiyath ad-Din Kaykhusrau II. The Middle East historian R. Stephen Humphreys speculates that Kaykhusrau was offered control of Amida and Hisn Kayfa in return for joining the alliance. Although al-Ashraf had assembled a formidable alliance against his brother, he was unable to use this to engage al-Kamil's forces as he was already ill by the time of the negotiations with the Seljuks, and he died on 4 Muharram 635/28 August 1237. His rival, al-Kamil, died on 6 March 1238, and the Ayyubid domain was thrown into fresh turmoil.
