The Holy Roman Empire, also known as the Holy Roman Empire of the German Nation after 1512, was a polity in Central and Western Europe, usually headed by the Holy Roman Emperor. It developed in the Early Middle Ages, and lasted for a millennium until its dissolution in 1806 during the Napoleonic Wars. Initially, it comprised three constituent kingdoms—Germany, Italy, and, from 1032, Burgundy—held together by the emperor's overlordship. By the 15th century, imperial governance became concentrated in the Kingdom of Germany, as the empire's effective control over Italy and Burgundy had largely disappeared.
