Jal?l ad-D?n Muhammad Balkh?, also known as Jal?l ad-D?n Muhammad R?m?, and more popularly in the English-speaking world simply as Rumi, was a 13th-century Persian poet, jurist, theologian, and Sufi mystic. Iranians, Turks, Afghans, Tajiks, and other Central Asian Muslims as well as the Muslims of the Indian subcontinent have greatly appreciated his spiritual legacy in the past seven centuries. Rumi's importance is considered to transcend national and ethnic borders. His poems have been widely translated into many of the world's languages and transposed into various formats. In 2007, he was described as the "most popular poet in America."
Rumi's works are written in Persian and his Mathnawi remains one of the purest literary glories of Persia, and one of the crowning glories of the Persian language. A Persian literary renaissance, alongside the development of Sufism, started in regions of Sistan, Khor?s?n and Transoxiana and by the 10th/11th century, it reinforced the Persian language as the preferred literary and cultural language in the Persian world. His original works are widely read today in their original language across the Persian-speaking world. Translations of his works are very popular in other countries. His poetry has influenced Persian literature as well as Urdu, Punjabi, Turkish and some other Iranic, Turkic and Indic languages written in Perso-Arabic script e.g. Pashto, Ottoman Turkish, Chagatai and Sindhi.
