Simin Behbahani started writing poetry at twelve and published her first poem at the age of fourteen. She used the "Char Pareh" style of Nima Yooshij and subsequently turned to "ghazal". Behbahani contributed to a historic development by adding theatrical subjects and daily events and conversations to poetry using the "ghazal" style of poetry. She has expanded the range of the traditional Persian verse forms and has produced some of the most significant works of the Persian literature in the 20th century.
