PRE-OTTOMAN PERIOD 
  
  The Huns
  
  The first Turkish  tribe  that is mentioned is
  the  Huns made  their appearance  in  the 8th Century B.C.
  Chinese sources refer to the Huns as Hiung-nu and its is here that the culture
  of horseback migration first makes its appearance in history. The Huns who
  migrated to the West in time achieved superiority over the Germans, of the
  same horseback discipline as themselves, and over the highly cultured Romans,
  because of their splendid state of readiness and amazing mobile capabilities.
  
The Gokturks
  
  Founded in 552 AD by Bumin Kagan, the Gokturks engaged
  in widespread diplomatic activity. Although the Gokturks were forced to become
  subjects of  China  in the 7th Century,  they  regained
  their  independence in 632, led by a hero named Kutluk. In the year 716
  Kutluk’s son Bilge Kagan  became the ruler, and  prosperity with 
  the aid of his  brother Kultegin and his father’s elderly vezir,
  Tonyukuk. This  lasted  until the  year 745. The famed Orhun 
  Epitaphs  from this period are made up of the tombstone inscriptions of
  Tonyukuk (d.720), Kultegin (d.731) and Bilge Kagan (d.734).
  
The Uygurs
  
  The rule of the Gokturks was brought to an end in the 
  year 745  by  the  Uygur, who were of the same  ethnic
  stock as themselves. In this manner all the Turks who had converged under the
  banner of the Gokturks were dispersed to that of the Uygurs and other tribes.
  It is because of the Uygurs that the agricultural basin became known as
  Turkistan. In the year 1229, the Mongols put an end to Uygur sovereignty; the
  Uygurs however became their cultural and political mentors.
  
The Turks
  and  Islam
  
  Contacts  between  the Turks a nd 
  Moslems  commenced  in  the beginning of the  8th Century
  and some of the Turks favoured Islam. However the pro-Arab policies of the
  Omayads (661-750 A.D.) restricted these relation somewhat. It is because of
  this that a major part of the political struggle  against  the 
  Omayads  at  that  time,  helping  the Abbasside
  dynasty to attain sovereignty, rested on the efforts of Moslem Turks and
  Iranians of the area (750 A.D.).Many Moslem Turks took office in the Abbasside
  government, and because of this, great interest  in  the 
  Islamic world  spread among the Turks beyond the River Ceyhun. The
  interest became even more pronounced when the Calph of the time Muktasim
  established an elite army formed only of Turks in 835. Commercial 
  relationships  also played a major role in the spread of Islam into the
  steppes of Central Asia. Turkish Sufi dervishes who joined the caravans 
  were  instrumental  converting the Turks to Islam. The Turks had
  become Moslem by the 10th century, and this resulted in the achievement of
  political unity. Following these developments, the first Muslim Turkish state
  was formed by the Karahans.
  
The Karahans
  
  The Karahans ruled between 990-1212 in Turkistan 
  and  Maveraunnehir  and  put an  end  to  the 
  sovereignty  of  the Samanogulları. The founder of the state is
  Satuk  Bugra  Khan, and this is  inscribed in the legend
  praising  Bugra  Khan. The reign of the Karahans is especially
  significant from the point of view  of  Turkish culture and art
  history. It  is  during this period that mosques, schools, bridges
  and  caravansarays  were  constructed  in  the
  cities. Buhara and Semerkand became centres of learning. In this period, the
  Turkish language found the means to develop. Among the most important works of
  the period is Kutadgru Bilik  (translated  as  The 
  Knowledge  That  Gives  Happiness) by Yusuf  Has 
  Habib, written between the years 1069-1070. It is a political work expressed
  in verse. This work in fact comprises knowledge for the ruler, in which Yusuf
  personalises his key principles of justice, power (state), comprehension
  (reason) and belief.
  
The
  Ghaznavids
  
  The Ghaznavi state was formed in the year 963 by the
  Turkish  ruler Bevuktekin and is one of the first  Moslem Turkish
  states. It is in the time of Bevuktekin’s son Mahmut that the state lived
  its brightest period (977-1030) Mahmut realized 17 sorties  and 
  missions  into  India;  he  worked  relentlessly 
  for the  expansion of Islam in the area and expanded the borders of the
  state from Toharistan and Maveraunnehir to Puncab, Multan  and  some
  districts of  the Sind. During the time of Mahmut’s son Mes’ud, the
  Ghaznavids lost a large part of their lands, following the battle of
  Dardanakan (1040) against the founder of  the Great  Selcuk 
  Empire  Tugrul  Bey . The  Ghaznavids  finally 
  collapsed  in  1186  and  were assimilated by the Oguz.
  
The Turkish
  scholar Ebu Reyhan el-Beyruni, brought to Gazne  by  Sultan 
  Mahmut  from  Harzem,  helped  make  this period an
  important one within Islamic cultural history. Beyruni, who wrote his works in
  Arabic, also wrote  the  famed Kitabn’ı-Hind (the Book of India)i
  which discussed the language, the literature, the religion and philosopy of
  India, from the campaigns of Mahmut. The famed work by the poet Firdevsi, the
  Sehname, was also presented (in 1009) to Sultan Mahmut during this period.
  
The Seljuks
  
  The Oguz, who destroyed the Ghaznavid state, succeeded
  in putting Anatolia, Iraq, the southern part of the  Caucasus, Azerbaijan
  and the north of Iran under Turkish rule. The Oguzs had first formed the
  Gokturk Empire in the 6th century; after the expansion of Islam among the
  Turks, the Oguz came to be called the Turkmens among the other Turks.
  
Seljuk, 
  whose  name  the  Seljuk  dynasty  adopted,  is
  the son of Dukak of the line of Kiniks, which is a branch of the Ucoks of
  Oguz. Tugrul Bey and Cagri (Cakir) Bey are the grandsons of  Seljuk, 
  in  whose  time  they, and  the  Oguzs, known 
  as  the  Seljuks  in  history,  subjected 
  Horasan,  defeated  the  Ghaznavid  ruler  Mesud 
  and   established  the  Great Seljuk Empire in 1040.
  
In 1071, the
  nephew of Tugrul Bey, Alp Arslan (1063-1072) fought the battle of 
  Malazgirt  and  having  defeated  the Byzantine
  Emperor’s forces in this battle opened the doors of Anatolia to the Muslim
  Turks.
  
The
  Anatolian Seljuks
  
  The year 1071 is considered to be the beginning of the
  Turks and that of  Islam in Anatolia. It is following this date that the
  Turks fully conquered the whole of Anatolia and establihed the Anatolian
  Seljuk state in Anatolia  as  a  part  of  the Great
  Seljuks Empire.
  
Although the first
  ruler and founder of the Anatolian Seljuks Suleyman Shah (d.1086) first
  establihed the capital in Iznik, in Bursa, he was later compelled to move the
  capital well into the interior of Anatolia, to Konya, during the  time 
  of  the First Crusade.
  
The first
  schooling institutions, the Moslem theological medreses, were formed in
  Anatolia during the time of Kilic Arslan (1153-1192). Following  the 
  establishment  of  two  medreses by Kilic Arslan, one in Konya
  and the other in Aksaray,
  the  medreses  of  Sircali  in 
  Konya  (1242-1243),  Karatay  (1251),  Ince  Minareli
  (1252-1253),  Atabekkiye  (after 1251-1268), Gokmedrese in Sivas
  (1271), Buruciyye (1271-1272), Cifte Minareli (1271), and the Cacoglu in
  Kirsehir (1272) were established.
  
The Seljuks also
  attributed much importance to the medical sciences and in almost  all 
  their  cities  treatment  institutions called Darush-Shifa,
  Darul-Afiye and Darus-Sihna and hospital were set up. The main medical
  treatment centres are the Gevher  Nesibe  in  Kayseri 
  (1205),  the Izzettin  I  Keykavus  in  Sivas (1217), 
  the  Torumtay in Amasya (1266), the Muinuddin Pervane in Tokat (1275),
  and the Pervaneoglu Ali in Kastamonu (1272).
  
Because of the
  influence of Persian aspects coming from Iran among the enlightened, the
  administrators, the men of arts and the traders, the anatolian Seljuk state
  became increasingly affected by Iranian culture and language.
  
The Beyliks
  
  The Period of Principalities
  Political unity in Anatolia was disrupted from the time
  of the collapse of the Anatolian Seljuk state at the beginning of the 14th
  century (1308), and until  the  beginning  of  the 
  16th  century  each  of  the  region  in 
  the  country  fell  under  the domination of  Beyliks
  (Principalities).  The  Principalities  were  formed 
  in  the  following  regions:  The  Eshrefoguls 
  in Beysehir (1328), the Karesioguls in Balikesir-Bergama (1336),  the
  Inancoguls  in  Denizli  (1368),  the  Hamidoguls 
  in Beysehir (1328), Hamidoguls in the Isparta-Antalya area (1391), the
  Aydinoguls in  the  Aydın-Izmir  area  (1405),  the
  Saruhanoguls in Manisa (1410), the Mentesoguls in Mugla area  (1425), 
  the  Candaroguls  in  Kastamonu  (1461),  the
  Dulkadiroguls in the Maras area (1521), and  the  Ramazanoguls 
  in  the Cukurova area (1608). The  Osmanoguls, who were to
  eventually destroy these Principalities and establish political unity  in
  Anatolia, lived in the Eskisehir, Bilecik  and Bursa areas.
  
On the other hand,
  the area in central Anatolia east of the Ankara-Aksaray line as far as the
  area of Erzurum remained under the administration of the Ilhani General
  Governor until 1336. The infighting which resulted  upon the death 
  of  the Ilhan ruler Ebu Said Bahadir Khan in 1338 gave the principalities
  in Anatolia their complete  independence. In  addition to this, new
  Turkish principalities were formed in the locaties  previously 
  under  Ilhan occupation. One of  these  is  the Eretna
  Principality formed by  the  Uygur  Turks  at  Eretna 
  in  the  Kayseri-Sivas  region.  In  the  same 
  area, another principality, the Turkmen  Kadi  Burhanettin 
  State,  was  formed  in  the  second part of the
  century. In this period, the Karakoyuns and the Akkoyuns started political
  activities in Eastern Anatolia.
  
During the 14th
  century, the Turkmens, who made up the western Turks, started to re-establish
  their  previous political sovereignty in the Islamic world.
  
Rapid developments
  in the Turkish language and culture took place during the time of the
  Anatolian Principalities. In this period, the Turkish language became used in
  the sciences and  in  literature,  and  became  the 
  official  language  of  the Principalities. New medreses were
  established and progress was made in the medical area during this period.
  
Gulsehri, Nesimi
  (d.1404) and Ahmedi (1335-1412) are the prominent Turkish language poets of
  the 15th century.
  
In the cities, the
  Turkish communities composed of villagers and Turkmen migrants started 
  to  form  guilds  among  the more populous craftsmen,
  calling themselves “Ahi”. These guilds pioneered the development of city
  life.
  
THE OTTOMAN PERIOD
  
The Ottoman
  Principality was founded  by  a Turkmen  tribe  living on 
  the Turkish-Byzantine border. The geographic location of the principality and
  the weak state of Byzantines combined to make the Ottoman  principality
  the strongest state within the Islamic world by the 14th century.
  
When, in the year
  1402, Tamerlane defeated the forces od  Yildirim  Beyazit, the
  principalities  which had come under Ottoman  sovereignty all became
  independent. A  unity between  them was  achieved  again
  in the middle  of  the 15th century.
  
When Fatih Sultan
  Mehmet conquered  the Byzantine capital in 1453, the Ottoman state became
  the  strongest  of  the time. The tolerant approach taken by
  Fatih Sultan Mehmet to other religions  and to  the adherents 
  thereof  became  a tradition adopted by his successors. Following
  the capture of Istanbul, the Orthodox Church was feed from obedience to the
  Catholic Church and granted its independence.
  
On  the 
  other  hand,  the  technical  superiority  of t he
  Ottoman army began to be evident; Selim the first (1512-1520) conquered the
  Safevi Ruler Shah Ismail (1514) with such an army and thereby obliterated 
  the Mamelake state in 1517. At the end of these battles, the Ottomans had
  added, in addition to the major part of east Anatolia, the lands considered
  holy in the Islamic worl-Mecca and Medine-to their territories.
  
The brightest
  period of the Ottoman State was during the reign of Sultan Suleyman
  (1520-1566)  when  the  boundaries of the Empire spread from
  the outskirts of Vienna to the Bay of Basra and from the Crimea to an expanded
  north Africa as far as Ethiopia.
  
The  Ottoman 
  Empire  continued  to  acquire  territory  until 
  the middle of the 17th century. In 1683, it suffered its first major loss with
  defeat in the siege of Vienna.
  
When the losses of
  land and defeats continued, the Ottoman Empire sought salvation in a series of
  renewal movements, taking the western institutions which had shown great
  developments after  the  Renaissance. As  a  result, 
  the  (nautical engineering) Muhendishane-i-Bahr-i Humayun was founded in
  1773 and the  (civil engineering) Muhendishane-i Berri-i Humayun in 1795.
  
The declaration of
  the Tanzimat Reform movement in 1839 is considered a major  link  in 
  the  chain  of  modernization events which had continued
  unabated since the beginning of the 17th century. The Tanzimat Reform period
  started with the reading on November 3, 1839, of the royal Tanzimat Decree by
  Mustafa Reshit Pasha in  Gulhane Park in Istanbul.
  
The 
  Tanzimat  Decree  is  considered  to  be  a 
  kind  of  constitution  giving  Turkey  the 
  means  to  enter  the road to
  contemporary civilisation.
  
The constitutions 
  of  the 19th  century  mostly  contained  provisions 
  that limit the rights and powers of monarchs. The major point in the Tazminat
  Reform Decree, that of equality under the law, brought about the development 
  of  political unity in the Ottoman state in a spirit of equality before
  the law. It is because of this policy  that  the  salient 
  point  in  the Islahat (Improvement) Decree of 1856 is t hat 
  of  egality  before the law. Later,  the  1876 
  constitution  contained  the following provision: “All individuals
  who are citizens of the Ottoman State are considered Ottoman regardless of
  Religion or Sect”.
  
The development of
  the principle of equality before the law in the west and its application in
  the Ottoman state  resulted in the different ethnic groups within the
  Empire becoming equal with Moslems in every sense and it is in this regard 
  that the first steps toward the separation of religion and state affairs were
  taken. In this period, the statues of more and more public bodies started to
  be changed away from  the  provisions  of  Islamic 
  jurisprudence  to  that  of  civil  codes.  The
  principles inherent in the Tanzimat Reform Decree thereby laid the basis for
  the constitutional regime of modern  Turkey and the realization of
  laicism.
  
Despite many
  internal problems and disturbances during the  reign  of 
  Abdulaziz  (1861-1876)  who  ascended  to  the throne
  after Abdulmecit, the effects of westernization in society became even more
  evident.
  
This influence was
  apparent in the field of literature. It is in this period that Constitution, 
  Parliament  and  similar  words began to be used. The group
  known  in  history  as  the  “Young Turks” 
  was  to  a  large  degree  responsible  for 
  this development. Namik Kemal, Ziya Pasha, Mustafa  Fazil  Pasha 
  and  his  friends  published  the  newspaper 
  “Hurriyet” (Freedom) in London in the year 1864. The literary beginnings 
  of  the  newspaper  later  gave  way  to 
  political  issues. Although it is because of these trends that the first
  constitution was promulgated under the leadership of Mithat Pasha in 1876, 
  Sultan  Addulhamid  II  (1876-1909)  used  the 
  Ottoman-Russian  war  (1877-78)  as  an  excuse 
  to  dissolve Parliament and effectively put an end to this constitutional
  period. This action of Abdulhamid the Second paved the way for an organized
  opposition movement. One of these organizations, the  Ittihat ve Terakki
  (Union and Progress) Society compelled Sultan Abdulhamid the Second to accede
  to a second constitutional  government system.  Ittihat  ve 
  Terakki won the majority and entered Parliament in 1908 as a party. It is
  during this period that  the  wars  of  Tripoli (1911-12)
  and the Balkans (1912-13) were lost, and the Ottoman State entered the First 
  World  War  in  1914.  On  side  of  the
  allied powers.
  
The Ottoman State
  emerged defeated from the war, together with her allies, and was compelled 
  to  sign  the  Mudrow Armistice on October 30, 1918. According
  to the terms of the armistice, the states were to be occupied by  the
  victors and opened to all shipping:; the Ottoman army was to be disbanded and
  all communication and transport  handed  over to the control of the
  victors.
  
Also among the
  terms of the armistice was a provision that the entente power  might 
  occupy  areas deemed  to  be  of strategic importance; the
  powers started to occupy Anatolia on November 1, 1918 according to these
  terms.
  
The 
  occupation  started  to  spread  out,  and  on 
  May  15, 1919,  the Greeks occupied  Izmir. A national 
  resistance movement commenced. In many areas of the country the Society For
  Defence of Rights (Mudafaa-i Hukuk) started to spring up, and the military arm
  of the society, called the Kuvayi Milliye, started to take action.
  
The resistance
  movement was, until Mustafa Kemal landed at Samsun, sporadic and disorganized:
  under his leadership the resistance became cohesive, its forces progressively
  turned into an organized army and the movement became a full scale war of
  independence.
  
Upon  the 
  foundation, on  April  23, 1920, of the Turkish Grand National
  Assembly in Ankara, a second Parliament to conduct the War of Independence
  outside of occupied Istanbul came into existence.
  
When 
  the  decisive  battle  at  Dumlupinar  on 
  August   26,  1922,  called the  “Battle  of  
  the  Commander-in-Chief” (Baskomutanlik Savasi), ended with victory for
  the Turkish force, and following this, Izmir was liberated, on September 9,
  1922, the War of Independence finally ended in victory.
  On November 1, 1922, the Sultanate was abolished. The
  last Ottoman Sultan Vahdettin left Istanbul on board a Brithis warship on
  November 17, 1922. Abdulmecit the second was appointed the Caliph in his
  place. More on Ottoman Empire
  
REPUBLIC OF TURKEY 
  
On July 24, 1923,
  the Lausanne Peace Agreement was signed, and  the Turkish Grand National 
  Assembly  announced on October 13, 1923 that Ankara was the new capital.
  
On October 29,
  1923, the Republic was proclaimed. On March 3, 1924, the Caliphate was
  abolished.
  
Following
  the foundation of the Republic, a series of reforms took place one after the
  other; through amendments to the civil code, women were given social rights
  and privileges, the Latin alphabet was adopted, and a secular state was
  formed.
