In the 11th century, [[Seljuk Empire |Seljuk]] domains stretched from the delta of the Amu Darya delta into Iran, Iraq, the Caucasus region, Syria, and Asia Minor. In 1040 the [[Seljuk Turks]] crossed the Oxus from the north, and having defeated Masud, sultan of Ghazni, raised Toghrul Beg, grandson of [[Seljuk (warlord)|Seljuk]], to the throne of Iran, founding the Seljukid dynasty, with its capital at [[Nishapur]]. A younger brother of Toghrul, Daud, took possession of [[Merv]] and Herat. [[Tughril I|Toghrul]] was succeeded by his nephew [[Alp Arslan]] (the Great Lion), who was buried at Merv. It was about this time that [[Merv]] reached the zenith of her glory. In 1055 Seljuk forces entered [[Baghdad]], becoming masters of the Islamic heartlands and important patrons of Islamic institutions. Until these revolts, Turkmen tribesmen were an integral part of the Seljuk military forces. Turkmen migrated with their families and possessions on Seljuk campaigns into Azerbaijan and Anatolia, a process that began the Turkification of these areas. During this time, Turkmen also began to settle the area of present-day Turkmenistan. Prior to the Turkmen habitation, most of this desert had been uninhabited, while the more habitable areas along the Caspian Sea, [[Kopet Dag|Kopetdag Mountains]], [[Amu Darya]], and [[Marghab River]] (Murgap Deryasy) were populated predominantly by Iranians. The city-state of [[Merv]] was an especially large sedentary and agricultural area, important as both a regional economic-cultural center and a transit hub on the [[Silk Road]].<ref name=lcweb /> The last powerful Seljuk ruler, Sultan [[Ahmad Sanjar]] (d. 1157), witnessed the fragmentation and destruction of the empire because of attacks by Turkmen and other tribes.<ref name=lcweb /> During the reign of Sultan Sanjar or Sinjar of the same house, in the middle of the 11th century, Merv was overrun by the Turkish tribes of the Ghuzz from beyond the Oxus. It eventually passed under the sway of the rulers of Khwarizm (Khiva). After mixing with the settled peoples in Turkmenistan, the Oguz living north of the Kopet-Dag Mountains gradually became known as the [[Turkmens|Turkmen]].

The Seljuk empire broke down in the second half of the 12th century, and the Turkmen became independent tribal federation.
