Otto Von Bismarck was a Prussian statesman born in 1815 who had a wild youth but found stability when he married and began his political career in 1847. He wanted to unite the many small German states into a single German Empire and served as Chancellor from 1871-1890, during which time he engineered the Austro-Prussian War of 1866 and Franco-Prussian War of 1870-1871 to expand Prussian and German territory. As Chancellor of the new German Empire, he established policies like building railways and compulsory military service.
