 Under Alexandru Coconul, the peasant cavalry, or "Călărași", staged a tax revolt, and was only narrowly defeated, by other branches of the Wallachian military forces, outside Buftea.One account suggests that Leon engaged in bribing the Ottoman officials, who would have ensured his appointment as Prince, running into massive debt.Eventually, Sultan Murad IV ordered Alexandru IV to step down and proclaimed Leon as the Prince; he took the throne at some point before October 15, 1629, and continued the process of Hellenization.
