The early years of Ottokar, a younger…

The early years of Ottokar, a younger son of King Vladislav II of Bohemia, had passed amid the anarchy which prevailed everywhere in the country.

After several struggles in which he had taken part, he had been recognized as ruler of Bohemia by Holy Roman Emperor Henry VI in 1192.

He was, however, soon overthrown for joining a conspiracy of German princes to bring down the Hohenstaufen monarchy.

In 1197, Ottokar had forced his brother, Duke Vladislaus III Henry, to abandon Bohemia to him and to content himself with Moravia.

Taking advantage of the German civil war between the Hohenstaufen claimant Philip of Swabia and the Welf candidate Otto IV, Ottokar declares himself hereditary King of Bohemia in 1198.

This title is supported by Philip of Swabia, who needs Czech military support against Otto.
