Answer:
European Plain, one of the greatest uninterrupted expanses of plain on the Earth’s surface. It sweeps from the Pyrenees Mountains on the French-Spanish border across northern Europe to the Ural Mountains in Russia. In western Europe the plain is comparatively narrow, rarely exceeding 200 miles (320 kilometres) in width, but as it stretches eastward it broadens steadily until it reaches its greatest width in western Russia, where it extends more than 2,000 miles.
Hello there!! Here is your answer: The Wars of religion were a series of religious wars which were waged in Europe in the 16th, 17th and early 18th centuries. The wars, which were fought after the Protestant Reformation began in 1517, disrupted the religious and political order in the Catholic countries of Europe. However, religion was not the only cause of the wars, which also included revolts, territorial ambitions, and Great Power conflicts. For example, by the end of the Thirty Years' War (1618–1648), Catholic France was allied with the Protestant forces against the Catholic Habsburg monarchy. The wars were largely ended by the Peace of Westphalia (1648), establishing a new political order that is now known as Westphalian sovereignty.
The conflicts began with the minor Knights' Revolt (1522), followed by the larger German Peasants' War (1524–1525) in the Holy Roman Empire. Warfare intensified after the Catholic Church began the Counter-Reformation in 1545 against the growth of Protestantism. The conflicts culminated in the Thirty Years' War (1618–1648), which devastated Germany and killed one-third of its population. The Peace of Westphalia (1648) put an end to the war by recognising three separate Christian traditions in the Holy Roman Empire: Roman Catholicism, Lutheranism, and Calvinism.[4][5] Although many European leaders were "sickened" by the bloodshed by 1648,[6] religious wars continued to be waged in the post-Westphalian period until the 1710s, including the Wars of the Three Kingdoms (1639–1651) on the British Isles, the Savoyard–Waldensian wars (1655–1690), and the Toggenburg War (1712) in the Western Alps. Popular memory of the wars lasted even longer. =THIS INFORMATION IS FOUND FROM WIKIPEDIA=
There were many significant political changes which Diocletian enacted. One important thing which happened was that he divided the Roman empire into two parts. This meant Rome was being effectively taken care of by two different emperors at the time for that reason.
