The Great InterregnumThe Great Interregnum- An interregnum (plural interregna or interregnums) is a period of discontinuity of a government, organization, or social order. The Great Interregnum (1256-1273 period) was in the Holy Roman Empire between the end of Hohenstaufen rule and the beginning of Habsburg rule. It was a time of anarchy and civil war. German princes gained power and vied for imperial title; Habsburgs of Austria provided all German kings and emperors from mid-fifteenth century until dissolution of Holy Roman Empire in 1806.
