Vlad Dracula conquers his father's throne
The reign
On August, 11, 1456 John Hunyadi dies by the pest epidemic that was transmitted from the Turks to the Christians predators of cadavers. On his funeral tomb in the Cathedral of Alba Iulia one could read “the World’s Light is off".
Vlad take advantage of this and, inspired also by the Halley comet that was visible in Europe for one month, starting with June, 8th, 1456, he grouped his men, cross the Carpathians and conquered Wallachia’s throne.
Vladislav II, surprised, opposed only a weak resistance and was betrayed by his men. He run away and was caught and killed on August, 20, near Târgşor, an important town of the medieval Wallachia, 60 km North to Bucharest, now disappeared. He was buried in Dealu Monastery, near Târgovişte. The place where Vladislav II was killed may be the church that he erected here in Târgşor. However five years later, Dracula erected another church in Târgşor, church that was finished on June, 24, 1461.
This might be as a sign of requiring forgiveness for killing Vladislav. Here are some remaining of the old church in Targsor, photo taken by myself two weeks ago:
