Statutum in favorem principum
Frederick II decreed this law in 1232 in confirmation of a grant made the previous year by his son Henry, King of Germany, under pressure from the German secular princes during his rebellion against his father. The terms were very similar to those conceded to the ecclesiastical princes or bishops in the Confoederatio cum principibus ecclesiasticis at the time of the Henry's coronation (in 1220), conferring similar rights.
In this law Frederick II relinquished a number of important Royal rights ("Regalia") to the secular princes. Among other things, they received the rights to mint coins and levy tolls in the German part of the Holy Roman Empire. In particular, however, Frederick granted them the right of approval over any legislation proposed in future by the Emperor.
The decreeing of this law together with the previous Confoederatio made the power and influence of the territorial princes in relation to the Empire and the towns extraordinarily great. Frederick's aim was to leave his Empire north of the Alps secure under the direct rule of the princes, allowing him to concentrate his efforts on the southern part of the Empire. This rule of the land by the princes was nevertheless secured at the expense of the centralised power of the monarchy.
