In the history of Iranian literature after Islam, poets of each era have been so influenced by their environment that they have left useful information about the political, social and civilizational history of their era and have spoken in various poetic forms of the state of their time, so that even historians can use these poems to gain a proper and complete understanding of the history of society and culture of that time. One of the historical events of Iran in the 6th century AH, which has been reflected in Persian poetry, is Oghuz Turks’ invasion of Khorasan. A group of poets from the 6th century have written vividly about it. In this article, the authors will examine this historical event in Iran and its political-social and literary consequences and show how a literary text – i.e. Persian ode – can reflect a historical event. After mentioning some descriptions about the Oghuz Turks and the Seljuk government's interaction with them and historical reports of their invasion of Khorasan, the reflection of this event in the odes of three important poets of this era: Anwari, Rashid al-Din Vatvat, and Khaghani Shirvani will be examined
