Know About German Empire

The German Empire (German: Deutsches Kaiserreich), variously referred to as Imperial Germany, German Reich/Realm, Second Reich and also (unofficially) as Germany, was the historical German nation state that existed from the unification of Germany in 1871 to the abdication of Kaiser Wilhelm II in November 1918, when Germany became a federal republic. It was a predecessor of today's Germany.
The German Empire consisted of 27 constituent territories, with most of them being ruled by royal families. While the Kingdom of Prussia contained most of the population and most of the territory of the empire, the Prussian leaders were supplanted by leaders from all over Germany, and Prussia itself played a lesser role. As Dwyer (2005) points out, Prussia's "political and cultural influence had diminished considerably" by the 1890s. The German Empire's three largest neighbours were all rivals: Imperial Russia to the east, France to the west, and Austria-Hungary, a rival but also an ally, to the south-east.
After 1850, the states of Germany had rapidly become industrialized, with particular strengths in coal, iron (and later steel), chemicals, and railways. In 1871, when the new German Empire was created, it had a population of 41 million people, and by 1913 this had increased to 68 million. A heavily rural collection of states in 1815, the united Germany became predominantly urban. During its 47 years of existence, the German Empire operated as an industrial, technological, and scientific giant, gaining more Nobel Prizes in science than Britain, France, Russia, and the United States combined.
