I found an article on wiki that shows "Kingdom of Germany" before creation of Holy Roman empire, but other articles show that there was "Middle Francia" and "Eastern Francia" before Holy roman empire. which one is true, did Kingdom of Germany really exist at some point in medieval Europe(before Holy Roman empire)??
The "Kingdom of Germany" and "East Francia" were in fact one and the same, or at least it can be said that the East Frankish kingdom transitioned into the Kingdom of Germany over a period of centuries. 'Germany' continued to exist after the formation of the Holy Roman Empire as one of its three constituent kingdoms, the others being Burgundy and Italy.
