Rumi lived most of his life under the Persianate Seljuk Sultanate of Rum, where he produced his works and died in 1273 AD. He was buried in Konya, and his shrine became a place of pilgrimage. Upon his death, his followers and his son Sultan Walad founded the Mevlevi Order, also known as the Order of the Whirling Dervishes, famous for the Sufi dance known as the Sama ceremony. He was laid to rest beside his father, and over his remains a shrine was erected. A hagiographical account of him is described in Shams ud-Din Ahmad Aflāki's Manāqib ul-Ārifīn (written between 1318 and 1353). This biography needs to be treated with care as it contains both legends and facts about Rumi. For example, Professor Franklin Lewis of the University of Chicago, author of the most complete biography on Rumi, has separate sections for the hagiographical biography of Rumi and the actual biography about him.
