German Empire

The German Empire (German: Deutsches Kaiserreich), officially the German Reich, 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.

The German Empire consisted of 27 constituent territories, with most being ruled by royal families. This included four kingdoms, six grand duchies, six duchies (five after 1876), seven principalities, three free Hanseatic cities, and one imperial territory. Although the Kingdom of Prussia contained most of the Empire's population and territory, it played a lesser role. As Dwyer (2005) points out, Prussia's "political and cultural influence had diminished considerably" by the 1890s.

After 1850, the states of Germany had rapidly become industrialized, with particular strengths in coal, iron (and later steel), chemicals, and railways. In 1871 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 any other country.
