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.

In 1208, he was declared of age and with a troop of knights, which he received through his marriage, he regained control over Sicily and south Italy, which had earlier been seized by adventurers and local barons. He was able to recover some of the regal areas that had gone out of hand during his minority. During this period, relations between him and the Pope strained.
In 1209, Pope Innocent III crowned Otto of Brunswick as the Holy Roman Emperor. During 1210-11 Otto came up as a threat to Sicily and challenged Fredrick II’s efforts and invaded the royal domain. However, Otto of Brunswick backed off when the princes of Germany dismissed Otto and elected Fredrick II as King.
In March 1212, he coronated his year old son Henry VII as the King of Sicily and left for Germany. Soon, he conquered south Germany and was re-elected as King of Germany at Frankfurt by majority of the princes which followed his coronation in Mainz on December 9, 1212.
In July 1214, he defeated Otto in the Battle of Bouvines.
In 1215, elected by the German princes, he was crowned king on July 23 in Aachen.
To put an end to the War of Succession, he helped Eudes III, Duke of Burgundy and Philip II of France in 1218 and in this pursuit he invaded Lorraine, captured Theobald, the Duke of Lorraine and Nancy and burned Nancy.
In November 22, 1220, he was coronated as the Holy Roman Emperor in St. Peter’s Church, Rome by Honorius III, while Henry, his eldest son held the title of the King of Romans. He bestowed significant benefits and advantages on the Italian ecclesiastics and declared laws to counter heretics.
He made efforts to consolidate his regency in Sicily in contrary to his promise to Pope Innocent III to detach Sicily from the empire. He revoked some benefits of the barons. During 1222 to 1224 he overpowered the Saracen rebels who later became his faithful subjects protecting him against the influence of the papacy.

In 1230, he resettled with the papacy by signing the ‘Treaty of San Germano’.
