Holy Roman Empire

The Imperial Diet served as the legislature of the Holy Roman Empire from the 12th century until 1806. Originally composed of princes and high clergy, the Diet later expanded to include counts, barons, and representatives from imperial and episcopal cities.1

Functioning as a deliberative body, the Diet was divided into three distinct collegesā€”the electors, the princes, and the citiesā€”which met separately to reach decisions. These decisions were consolidated into a formal statement known as the conclusum imperii, which, once finalized as the Reichsabschied (recess of the empire), was presented to the emperor for ratification. While the emperor could accept or reject the recess, he lacked the authority to modify its language.1

Until the 17th century, the Diet held significant legal power, including the authority to decide matters of war and peace. However, following the Peace of Westphalia in 1648, its influence waned as it evolved into an assembly of sovereign envoys, eventually becoming the permanent, largely powerless "Everlasting Diet" at Regensburg until the empire's collapse.1
