The 13th century marks the ascendancy of lyric poetry with the consequent development of the ghazal into a major verse form, as well as the rise of mystical and Sufi poetry. This style is often called Araqi (Iraqi) style, (western provinces of Iran were known as The Persian Iraq (Araq-e-Ajam) and is known by its emotional lyric qualities, rich meters, and the relative simplicity of its language. Emotional romantic poetry was not something new, however, as works such as Vis o Ramin by As'ad Gorgani, and "Yusof o Zoleikha" by Am'aq Bokharai exemplify. Poets such as Sana'i and Attar (who ostensibly inspired Rumi), Khaqani Shirvani, Anvari, and Nizami, were highly respected ghazal writers. However, the elite of this school are Rumi, Saadi, and Hafiz Shirazi.
