Early modern period
In the early modern period, the Holy Roman Empire was a union of territories in Central Europe under a Holy Roman Emperor the first of which was Otto I. The last was Francis II, who abdicated and dissolved the Empire in 1806 during the Napoleonic Wars. Despite its name, for much of its history the Empire did not include Rome within its borders.
History of Europe
The Roman Empire had been repeatedly attacked by invading armies from Northern Europe and in 476, Rome finally fell. Romulus Augustus, the last Emperor of the Western Roman Empire, surrendered to the Germanic King Odoacer. The British historian Edward Gibbon argued in "The History of the Decline and Fall of the Roman Empire" (1776) that the Romans had become decadent, they had lost civic virtue.
