Stuttgart's literary tradition also bore yet more fruits, being the home of such writers of national importance as Wilhelm Hauff, Ludwig Uhland, Gustav Schwab, and Eduard Mörike. From 1841 to 1846, the Jubiläumssäule was erected on the Schlossplatz before the New Palace according to the plans of Johann Michael Knapp to celebrate the rule of King Wilhelm I. A decade later, the Königsbau was constructed by Knapp and court architect Christian Friedrich von Leins as a concert hall. Another milestone in Stuttgart's history was the running of the first rail line from Cannstatt to Untertürkheim on 22 October 1845. The advent of Industrialisation in Germany heralded a major growth of population for Stuttgart: In 1834, Stuttgart counted 35,200 inhabitants, rose to 50,000 in 1852, 69,084 inhabitants in 1864, and finally 91,000 residents in 1871. By 1874, Stuttgart once again exceeded the 100,000 inhabitant mark. This number doubled, due to the incorporation of local towns, to approximately 185,000 in 1901 and then 200,000 in 1904. In 1871, Württemberg joined the German Empire created by Otto von Bismarck, Prime Minister of Prussia, during the Unification of Germany, as an autonomous kingdom.
