Childhood & Early Life
He was born on December 26, 1194 in Iesi, Italy, as the son of Emperor Henry VI and Constance of Hauteville and was baptised in Assisi.
During his infancy in 1196, he was elected King of the Germans by the princes at Frankfurt but Henry VI was not successful in garnering support of the princes to make his son’s succession hereditary.
His father died in September 1197 following which the otherwise strong Roman Empire went through turbulence.
On May 17, 1198, he was coroneted as King of Sicily at two years of age while Constance of Hauteville became the regent for her son. She disestablished the bond of Sicily with that of the empire and with Germany by sending back the German counsellors and giving up Frederick’s claim to the empire and the German throne. This was followed by election of two rival kings - Otto of Brunswick and Philip of Swabia.
Constance appointed Pope Innocent III as guardian of Frederick II and also as regent of the Empire of Sicily which was under the suzerainty of the papacy.
He came under the tutelage of Cencio, who later went on to become Pope Honorius III. The next few years Sicily witnessed anarchism with local barons, papal leaders, German captains and cities of Pisa and Genoa fighting vigorously to acquire control over the land.
The turbulence continued till November 1206 when the imperial chancellor took over Palermo and ruled the country in Fredrick II’s name.
