Dan II of Wallachia

Dan II (? – June 1, 1432) was a voivode (prince) of the principality of Wallachia in the 15th Century, ruling an extraordinary five times, and succeeded four times by Radu II Chelul, his rival for the throne. Of those five periods on the throne of Wallachia (1420–1421, 1421–1423, 1423–1424, 1426–1427, and 1427–1431), four were within a period of only seven years.
