Murad II, Ottoman sultan (b. 1404)
Murad II (Ottoman Turkish: مراد ثانى, romanized: Murād-ı sānī, Turkish: II. Murad, 16 June 1404 – 3 February 1451) was the sultan of the Ottoman Empire from 1421 to 1444 and again from 1446 to 1451.

Murad II's reign was a period of important economic development. Trade increased and Ottoman cities expanded considerably. In 1432, the traveller Bertrandon de la Broquière noted that Ottoman annual revenue had risen to 2,500,000 ducats, and that if Murad II had used all available resources he could easily have invaded Europe.
