The holy Roman empire

"The Holy Roman Empire (Latin: Imperium Romanum Sacrum, German: Heiliges Römisches Reich, Italian: Sacro Romano Impero) was a varying complex of lands[1] that existed from 962 to 1806 in Central Europe. It grew out of East Francia, one of the primary divisions of the Frankish Empire. Its character changed during the Middle Ages and the Early Modern period, when the power of the emperor gradually weakened in favour of the princes. In its last centuries, it had become quite close to a union of territories. The empire's territory lay predominantly in Central Europe and at its peak in 1050 under Henry III, Holy Roman Emperor, included territories of the Kingdom of Germany, Kingdom of Bohemia, Kingdom of Italy and the Kingdom of Burgundy. For much of its history, the Empire consisted of hundreds of smaller sub-units, principalities, duchies, counties, Free Imperial Cities and other domains."--Wikipedia.
