Geography[link]

The surface area of the province of Erzurum is the fourth biggest in Turkey. The majority of the province is elevated. Most plateaus are about 2,000 m (6,500 ft) above sea level, and the mountainous regions beyond the plateaus are 3,000 m (9,800 ft) and higher. Depression plains are located between the mountains and plateaus. The southern mountain ranges are Palandöken Mountains (highest peak Büyük Ejder 3,176 m high) and Şahveled Mountains (highest peak Çakmak Mountain 3,063 m high). The northern mountain ranges are the second row elevations of the North Anatolian Mountains, i.e. Mescit Mountains (highest peak 3,239 m), Kargapazarı Mountains (highest peak 3,169 m) and Allahuekber Mountains. The two depression plains between these mountainous areas are Erzurum Plains and Hasankale Plains.

Continental climate rules in the province with long and harsh winters, and short and mild summers. The average low temperature is -8.6 °C (16 °F), while the average high temperature is 12°C (53.6 °F). Average annual precipitation is 453 mm. Snow falls on an average of 80 days and remains for about 150 days.

Steppe formations are prevalent geographic features of this province, occupying about 60% of the surface area, much of it fertile. Forested areas are small, mainly consisting of scots pines and oaks.

The eastern part of the province lies in the basin of the Aras river, the western part in the Karasu (Euphrates) basin, and the northern part in the Çoruh basin.

There are few natural lakes in the province, the major one being Lake Tortum (approximately 8 km²) fed by the Tortum (Uzundere) Falls. A hydroelectric power plant built in 1963 is situated on the inlet of this lake. There are three artificial lakes in the province.

History[link]

Known as Arzen, Erzen, and Karin most of the province was incorporated to the Roman Empire in 4th century who founded a city called Erzen. The Byzantine Empire also built a city in the region, called Theodosiopolis, which was on the border. Standing on the crossroads of main trade routes in Asia Minor, the area was a center of importance for Greeks, among them this area had population of Syriac Christians, Jews, Armenians, and Assyrians. Persians and Arabs who frequently clashed with the Byzantine Empire. The city was also part of the Armenian kingdom of Tayk in the 10th century. Threatened by and later devastated and looted by the Seljuk Turks in 1049, the older city of Erzen was conquered, but Theodosiopolis survived the invasion. The ruling dynasty of the time was that of the Saltukids.

Theodosiopolis repelled many attacks and military campaigns by the Seljuks and Georgians (the latter knew the city as Karnu-Kalaki^[2]) until 1201 when the city and the province was conquered by the Seljuk sultan Süleiman II of Rüm. Erzen-Erzurum fell to the Mongol siege in 1242, and the city was looted and devastated. After the fall of the Seljuk Sultanate of Anatolia (Rüm) in early 14th century, it became an administrative province of the Ilkhanates, and after their fall, became part of the Çoban beylik, Black Sheep Turkmen, Mongols led by Timur Lenk and White Sheep Turkmen. Finally, in 1514 the region was conquered by the Ottoman Sultan Suleiman the Magnificent.

During the Ottoman reign, the city served as the main base of Ottoman military power in the region. Early in 17th century, the province was threatened by Iran and a revolt by the province governor Abaza Mehmed Pasha. This revolt was combined with Jelali Revolts (the uprising of the provincial musketeers called the Celali), backed by Iran and lasted until 1628.

The city was conquered by the Russian army in 1829, given back to the Ottoman Empire with the Treaty of Adrianople (Edirne). The poet Alexander Pushkin accompanied the Russian commander-in-chief, Ivan Paskevich, during that expedition and penned a brief account of the campaign. The city was again assaulted by the Russian army in the last Russo-Turkish War in 1877.

The province was the site of the major fighting during Caucasus Campaign of World War I between Russian and Ottoman forces including the key confrontation of the campaign, Battle of Erzurum which resulted in capture of Erzurum by Russian army under command of Grand Duke Nicholas on February 16, 1916. It was returned to the Ottomans with the Treaty of Brest-Litovsk in 1918. Erzurum was also a main Turkish base during the Turkish War of Independence. It was declared a province of Turkey in 1924.

Economy[link]

Approximately 18.5% of the total surface area is arable land, of which about 75% has permanent crops. A large portion of the agricultural produce consists of cereals. Forested areas occupy 8.8% of the total surface area, with forestry a local industry. Industries largely consist of manufacturing of forestry, agriculture, husbandry, chemistry, textile and mining products. There are 81 active industrial plants in the province, most of them located at the central district of Erzurum, and are small and medium enterprises. Due to their relatively small sizes, these industries mainly serve local markets causing lower capacity usage, low productivity and unemployment. About 40 plants are currently out of use, mostly due to high operating costs.

The province of Erzurum has the highest ratio of meadows and pastures in Turkey, ideal for livestock. However, once the main occupation of the population, animal husbandry lost its importance in 1980s with the introduction of liberal economy and importation of animal products. A large organized industrial park concentrating on processing meat is being built with the hope of reviving this sector. Food products include beekeeping and trout farming.

Mining resources include lead, copper, chromium, and zinc which are of low tenure or have their reserves almost exhausted. There is a considerable amount of lignite, however because its ash and sulfur ratios are high, it suitable only for industrial use. Magnesite, fire clay, gypsum, manganese, diatomite, marble, rock salt and perlite are also present. The few natural geothermal resources, except one, are not suitable for economic investments, and they are used as natural springs.

GDP of the province of Erzurum is USD 1.16 billion, constituting less than 1% of the total and ranking 40th among Turkish provinces (1997 values).

Transportation is possible via paved and unpaved highways. The Erzurum international airport is open for commercial flights and is also utilized by the Turkish Air Force. The runways of this airport are the second longest in Turkey. Erzurum is also the main railroad hub in the Eastern Anatolia region.

The largest contributor to the provincial economy, in recent years, has been Atatürk University which is also one of the largest universities in Turkey, having more than forty-thousand students. Tourist activities including skiing, rafting and mountaineering, also provide a substantial proportion of the province's income. Skiing activities are centered on Palandöken Mountain.

Erzurum has some of the finest winter sports facilities in Turkey and hosted the 2011 Winter Universiade.

History[link]

Early history[link]

In ancient times, Erzurum existed under the Armenian name of Karin. During the reigns of the Artaxiad and Arsacid kings of Armenia, Karin served as the capital of the eponymous canton of Karin. After the partition of Armenia between the Roman Empire and Sassanid Persia in 387 AD, the city passed into the hands of the Romans. They fortified the city and renamed it Theodosiopolis, after Emperor Theodosius I.^[1] As the chief military stronghold along the eastern border of the empire, Theodosiopolis held a highly important strategic location and was fiercely contested in wars between the Byzantines and Persians. Emperors Anastasius I and Justinian I both refortified the city and built new defenses during their reigns.^[2]

Middle Ages[link]

The Seljuk era Çifte Minareli Medrese (Twin Minaret Madrasa) is the symbol of the city and appears on its coat of arms.

Theodosiopolis was conquered by the Umayyad general Abdallah ibn Abd al-Malik in 700/701. It became the capital of the emirate of Ḳālīḳalā and was used as a base for raids into Byzantine territory. Though only an island of Arab power within Christian Armenian-populated territory, the native population was generally a reliable client of the Caliph's governors. As the power of the Caliphate declined, and the resurgence of Byzantium began, the local Armenian leaders preferred the city to be under the control of powerless Muslim emirs rather than powerful Byzantine emperors.^[3]

In 931, and again in 949, Byzantine forces led by Theophilos Kourkouas, grandfather of the future emperor John I Tzimiskes, captured Theodosiopolis. Its Arab population was expelled and the city was resettled by Greeks and Armenians.^[4] Emperor Basil II rebuilt the city and its defenses in 1018 with the help of the local Armenian population.^[5] In 1071, after the decisive battle at Manzikert, the Seljuk Turks took possession of Theodosiopolis. The Saltukids were rulers of an Anatolian beylik (principality) centered in Erzurum, who ruled from 1071 to 1202. Melike Mama Hatun, sister of Nâsırüddin Muhammed, was the ruler between 1191 and 1200.

Theodosiopolis repelled many attacks and military campaigns by the Seljuks and Georgians (the latter knew the city as Karnu-Kalaki) until 1201 when the city and the province was conquered by the Seljuk sultan Süleymanshah II. Erzen-Erzurum fell to the Mongol siege in 1242, and the city was looted and devastated. After the fall of the Seljuk Sultanate of Anatolia (Rüm) in early 14th century, it became an administrative province of the Ilkhanate, and after their fall, became part of the Çoban beylik, Black Sheep Turkmen, empire of Timur Lenk and White Sheep Turkmen. Finally, in 1514 the region was conquered by the Ottoman Sultan Selim I, so called Selim the Inflexible. During the Ottoman Empire reign, the city served as the main base of Ottoman military power in the region.

It was the capital of the eyalet of Erzurum. Early in the seventeenth century, the province was threatened by Safavid Persia and a revolt by the province governor Abaza Mehmed Pasha. This revolt was combined with Jelali Revolts (the uprising of the provincial musketeers called the Jelali), backed by Iran and lasted until 1628.

Modern history[link]

The city was captured by the Russian Empire in 1829, but was returned to the Ottoman Empire under the Treaty of Adrianople (Edirne), in September of the same year. During the Crimean war Russian forces approached Erzurum, but did not attack it because of insufficient forces and the continuing Russian siege of Kars. The city was unsuccessfully attacked (Battle of Erzurum (1877)) by a Russian army in the Russo-Turkish War of 1877-78. However in February 1878, the Russians took Erzurum without resistance, but it was again returned to the Ottoman Empire, this time under the Treaty of San Stefano. There were massacres of the city's Armenian citizens during the Hamidian massacres (1894–1896).^[7][8] The city was the location of one of the key battles in the Caucasus Campaign of World War I between the armies of the Ottoman and Russian Empires. This resulted in the capture of Erzurum by Russian forces under the command of Grand Duke Nicholas and Nikolai Nikolaevich Yudenich on February 16, 1916.

Erzurum was also a major deportation center during the Armenian Genocide in 1915.^[9] In the late April 1915, about 450 prominent Armenians of Erzerum city were imprisoned. Most of them were intellectuals,community leaders, journalists and merchants. In early May 1915 they were all executed.^[10] Prior to the war, the city had a vibrant Armenian community with numerous schools and served as the provincial residence of the Archbishop of the Armenian Apostolic Church. By the time the Russians entered in 1916, barely a hundred Armenians were left alive, out of a prewar population of 20,000;^[11] it is estimated that approximately 90% of the Armenians of Erzurum province had perished.^[12] By 1919, according to the American Committee for Relief in the Near East, Erzurum was left completely devoid of its Armenian population.^[13] It is reported in Turkish sources that some Armenian troops serving in the Russian army carried out revenge killings in the area of Erzurum, after having witnessed the destruction that had been wrought against the Armenian population.^[14]

Erzurum reverted to Ottoman control after the signing of the Treaty of Brest-Litovsk in March 1918. In 1919, Mustafa Kemal Atatürk, one of the key founders of the modern Turkish Republic, resigned from the Ottoman Army in Erzurum and was declared an "Honorary Native" and freeman of the city, which issued him his first citizenship registration and certificate (Nüfus Cuzdanı) of the new Turkish Republic. The Erzurum Congress of 1919 was one of the starting points of the Turkish War of Independence.^[15]

Name and Etymology[link]

The name "Erzurum" derives from Artsn (Arcn, Artze), a neighboring commercial city that was subjected to a heavy sack by the Seljuk Turks in 1048-49. When its Armenian, Syrian, and other Christian inhabitants relocated to Erzurum (then named Theodosiopolis), they began calling it "Artsn Rum" (Arzan ar-Rum).^[16] To the Arabs, the city was known as Ḳālīḳalā (which was adopted from the original Armenian name Karno K'aghak', or Karin City, to differentiate it between the canton of Karin (Կարին).^[17] It was still referred to as "Karin" (Armenian: Կարին) by Armenians during the modern period. During Roman times it was renamed Theodosiopolis (Latin: Theodosiopolis, Greek: Θεοδοσιούπολις), acquiring its present name after its conquest by the Seljuks following the Battle of Manzikert in 1071.^[17]

Climate[link]

Erzurum has a humid continental climate (Köppen Climate Classification Dfb). Summer is breif, but summer days are very warm, though with cool nights. The average maximum during August is around 28°C (82°F). The highest recorded temperature is 36.5°C (97.7°F), on 31 July 2000. Winters are very cold, with an average minimum during January of around -16°C (3°F); temperatures fall below -30°C (-22°F) most years. The lowest recorded temperature is -37.2°C (-34.96°F), on 28 December 2002.

Economy[link]

One of the largest source of income and economic activity in the city has been Atatürk University. Established in 1950, it is one of the largest universities in Turkey, having more than forty-thousand students. Tourism also provides a portion of the province's revenues. The city is a popular destination in Turkey for winter sports at the nearby Palandöken Mountain.

Erzurum is notable for the small-scale production of objects crafted from Oltu stone: most are sold as souvenirs and include prayer beads, bracelets, necklaces, brooches, earrings and hairclips.

For now, Erzurum is the ending point of the South Caucasus Pipeline, also called the Baku-Tbilisi-Erzurum (BTE) pipeline. Erzurum will also be the starting point of the planned Nabucco pipeline which will carry natural gas from the Caspian Sea basin to the European Union member states. The intergovernmental agreement between Turkey, Romania, Bulgaria, Hungary and Austria to build the Nabucco pipeline was signed by five Prime Ministers on 13 July 2009 in Ankara.^[18][19] The European Union was represented at the ceremony by the President of the European Commission Jose Manuel Barroso and the Commissioner for Energy Andris Piebalgs, while the United States was represented by the Special Envoy for Eurasian Energy Richard Morningstar and the Ranking Member of the United States Senate Committee on Foreign Relations Senator Richard Lugar.^[20][21]

Tourism[link]

The citadel

Little of medieval Erzurum survives beyond scattered individual buildings such as the citadel fortress, and the 13th century Çifte Minareli Medrese (the "Twin Minaret" madrasa).

Six kilometres to the south of the center of Erzurum is an important skiing center on the Palandöken Mountain range. There are several ski runs; the south ski run is 8 km long, while the north ski run is intended for advanced skiers. The summit of Mt. Palandöken, which is called Büyük Ejder (Great Dragon), is at an altitude of 3188 metres. It can be reached with a chair lift which rises until an altitude of 3100 metres.

Transport[link]

The main bus station has bus links to most major Turkish cities. Erzurum is also the main railroad endpoint for the Eastern Anatolia region. Erzurum Airport, also used by the Turkish Air Force, has the second longest runway in Turkey.

Cuisine[link]

One specialty of Erzurum's cuisine is Cağ Kebab. Although this kebab variety is of recent introduction outside its native region, it is rapidly attaining widespread popularity around Turkey.

Kadayıf Dolması is an exquisite dessert made with walnut.

Erzurum hosted the following international winter sports events:

• January 27-February 6, 2011 25th Winter Universiade
• March 8–14, 2010 12th World Ice Hockey U18 Championships-Division III-Group A
• March 9–15, 2009 11th World Ice Hockey U18 Championships-Division III-Group B

The city's football club Erzurumspor, which played in the years ⋅1998-2001 in the Turkish Super League, was forced to relegate to the TFF Third League due to financial problems.

Erzurum's football venue, the Cemal Gürsel Stadium, has a seating capacity for 21,900 spectators. To be able to carry out the competitions of the Winter Universiade, a ski jumping ramp, an ice hockey arena and a curling hall were built in Erzurum.
