Research Article      Classification and analysis of why Persian poetry types and genres are important literary issues. Unfortunately, the field of poetry of the seventies, which included the most influential contemporary poetic movements; has been abandoned in this regard. In the seventies of Iran, we see the simultaneous presence of three independent branches of Americanisms, Europeanisms and return avant-garde with different origins, each of which has played an important role in guiding poets and writers of the seventies and later periods. The Americanisms announced their presence in Iran by Reza Braheni and the postmodern movement. Braheni's "Language Poetry", Ali Babachahi's "Pasanimaie" (means Post-Nimaie) and the students of Brahen's workshop, as well as Mohammad Azarm's "Different" poetry in the eighties are in this group. Europeanisms were active in this period with two branches of Ghazal and Free Poetry. In Ghazal, Simin Behbahani was the founder of "New-Ghazal", "Story- Ghazal" and " Narrative-Ghazal", Also, the students of Simin Behbahani, namely Mohammad Saeed Mirzaei, Arash Azarpeyk, Hooman Azizi, Amir Marzban, etc., whom were known in " Form-Ghazal" And in the field of Free Poetry, the "Movement Poetry" by Abolfazl Pasha, who is a follower of the Baroque in this group.Returning avant-gardeists came to the fore with its founder, Arash Azarpeyk, with the beginning of the era of Orianism and the proclamation of the millennium of Orianism in the history of thought. The result of Arash Azarpeyk's attitude is a variety of genres, including "Vazhaneh", " Minimal Ghazal", "Fara-Poem", "Fara-Form", "Noghlandaraneh" and more than thirty other genres so far. Among the followers of Arash Azarpeyk's philosophical literary genre, we can mention Tahereh Ahmadi, Aso Avesta, Hengameh Ahura, Seti Sara Sushian, Rabe’e Shams, Zartosht Mohammadi, Niloufar Masih, Ario Hemmati, Shahriyar Mirzapour and others.This research, using descriptive-analytical method and using library resources, divides and examines the three poetic tendencies of the seventies by separating their branched genres.
