The Turkish Land Forces (Turkish: "Türk Kara Kuvvetleri" ), or Turkish Army (Turkish: "Türk Ordusu" ), is the main branch of the Turkish Armed Forces responsible for land-based military operations.
 Official claims state that the army was founded by Modu Chanyu of the Xiongnu Empire in 209 BC, but the modern history of the army began with its formation after the collapse of the Ottoman Empire.
 Significant events since the foundation of the Army include combat in the Korean War and in the 1974 Turkish invasion of Cyprus, and acting as a NATO bulwark along Cold War frontiers through 1992.
 The army holds the preeminent place within the armed forces.
 It is customary for the Chief of the General Staff of the Republic of Turkey to have been the Commander of the Turkish Land Forces prior to his appointment as Turkey's senior ranking officer.
 Alongside the other two armed services, the Turkish Army has frequently intervened in Turkish politics, which has now been regulated to an extent with the reform of the National Security Council.
 The current commander of the Turkish Land Forces is General Salih Zeki Çolak.
Colonel Necabettin Ergenekon (born 1926, in Erzurum) is a Turkish Army officer who retired in 1982, having been commander of the Turkish Gendarmerie in Adıyaman Province after the 1980 Turkish coup d'état.
 Born "Necabettin Baltacı", he changed his name "some time in the '60s" to avoid confusion with another person by the same name.
 At one time, Ergenekon was the commanding officer of Veli Küçük.
 Ergenekon was suspected by later-assassinated state prosecutor Cevat Yurdakul as being behind a string of mysterious deaths in the 70s, but no legal action was ever taken.
The term "Anarchy at Samarra" refers to the period 861–870 in the history of the Abbasid Caliphate, which was marked by extreme internal instability and the violent succession of four caliphs, who became puppets in the hands of powerful rival military groups.
 The term derives from the then capital and seat of the caliphal court, Samarra.
 The "anarchy" began in 861, with the murder of Caliph al-Mutawakkil by his Turkish guards.
 His successor, al-Muntasir, ruled for six months before his death, possibly poisoned by the Turkish military chiefs.
 He was succeeded by al-Musta'in.
 Divisions within the Turkish military leadership enabled Musta'in to flee to Baghdad in 865 with the support of some Turkish chiefs (Bugha the Younger and Wasif) and the Tahirids, but the rest of the Turkish army chose a new caliph in the person of al-Mu'tazz and besieged Baghdad, forcing the city's capitulation in 866.
 Musta'in was exiled and executed.
 Mu'tazz was able and energetic, and tried to control the military chiefs and exclude the military from civil administration.
 His policies were resisted, and in July 869 he too was deposed and killed.
 His successor, al-Muhtadi, also tried to reaffirm the Caliph's authority, but he too was killed in June 870.
 With Muhtadi's death and the ascension of al-Mu'tamid, the Turkish faction around Musa ibn Bugha, closely associated with Mu'tamid's brother and regent al-Muwaffaq, became dominant in the caliphal court, ending the "anarchy".
 Although the Abbasid Caliphate was able to stage a modest recovery in the following decades, the troubles of the "Anarchy at Samarra" inflicted great and lasting damage on the structures and prestige of the Abbasid central government, encouraging and facilitating secessionist and rebellious tendencies in the Caliphate's provinces.
Ali Çetinkaya, also known as "Kel" Ali Bey (1878 – 21 February 1949) was an Ottoman born Turkish army officer and politician who served eight terms in the Grand National Assembly of Turkey, including a period in 1939–40 as his country's first Minister of Transport.
Nureddin Ibrahim Pasha (Turkish: "Nurettin Paşa, Nureddin İbrahim Paşa" ; 1873 – 18 February 1932), known as Nureddin İbrahim Konyar after 1934 and often called Bearded Nureddin (Turkish: "Sakallı Nurettin" ), was a Turkish military officer who served in the Ottoman Empire during World War I and in the Turkish army during the Eastern Front of the Turkish War of Independence.
 To distinguish him from namesakes, he was called Beard Nureddin because he was the only high-ranking Turkish officer during the Turkish War of Independence sporting a beard.
 He is known as one of the most important commanders of the War.
