Jalaal al-Din Muhammad Roumi (جلال‌الدین محمد رومی‎), is also known as Jalaal ad-Din Muhammad Balkhi, Mawlana (مولانا, our master), Mawlawi (مولوی, my master), and Rumi was born on September 30^th, 1207 and passed on December 17^th, 1273.  He was a 13th-century Persian poet, Islamic scholar, and Sufi mystic originally from Greater Khorasan. 

Rumi's work does not belong to a specific region as it goes across various borders and ethnic divisions: Iranians, Tajiks, Turks, Greeks, Pashtuns, all Persian speaking nations, and other Central Asian Muslims have greatly appreciated his spiritual legacy for the past seven centuries.  His poems have been widely translated into many of the world's languages. Rumi has been described as the "most popular poet" and the "best selling poet" in the United States.

Rumi's works are written mostly in Persian, but occasionally he also used Turkish, Arabic, and Greek in his verse.
