In the fifth century three wandering tribes, invaded the Empire, from the banks of the Vistula, the Dnieper, and the Volga respectively. The Huns came from the Volga, in the extreme east, and under Attila, "the Hammer of God," wrought consternation in the Empire; the Visigoths, from the Dnieper, attacked the Eastern Empire; while the Vandals, from the Vistula, took a triumphant course through Gaul and Spain, and founded for a time a Vandal empire in North Africa. One of the consequences of this movement was to drive several of the German tribes into France, Italy, and Spain, and even over into Britain; for it is from this stage in the world's history that we can trace the beginning of England, properly so called, just as the invasion of Gaul by the Franks at this time means the beginning of French history. By the eighth century the kingdom of the Franks extended all over France, and included most of Central Germany; while on Christmas Day, 800, Charles the Great was crowned at Rome, by the Pope, Emperor of the Holy Roman Empire, which professed to revive the glories of the old empire, but made a division between the temporal power held by the Emperor and the spiritual power held by the Pope. One of the divisions of the Frankish Empire deserves attention, because upon its fate rested the destinies of most of the nations of Western Europe. The kingdom of Burgundy, the buffer state between France and Germany, has now entirely disappeared, except as the name of a wine; but having no natural boundaries, it was disputed between France and Germany for a long period, and it may be fairly said that the Franco-Prussian War was the last stage in its history up to the present. A similar state existed in the east of Europe, viz. the kingdom of Poland, which was equally indefinite in shape, and has equally formed a subject of dispute between the nations of Eastern Europe. This, as is well known, only disappeared as an independent state in 1795, when it finally ceased to act as a buffer between Russia and the rest of Europe. Roughly speaking, after the settlement of the Germanic tribes within the confines of the Empire, the history of Europe, and therefore its historical geography, may be summed up as a struggle for the possession of Burgundy and Poland.
