Question: When did the industrial revolution start in the country where Ernst Lubitsch was born?

full_context: Document 1: Life in Great Britain during the Industrial Revolution: Life in Great Britain during the Industrial Revolution underwent vast social and economic changes, the result of developments in mechanised working methods, and the introduction of the factory system and the steam engine. The Industrial Revolution began in Great Britain about 1760, continuing through to the early 19th century. The lives of large sections of the population of Great Britain underwent massive changes during the Industrial Revolution. Work became more regimented and disciplined and began to take place outside the home. A movement of the population to the cities from the countryside produced dramatic changes in lifestyle.
Document 2: Shoe Palace Pinkus: Shoe Palace Pinkus (German: Schuhpalast Pinkus) is a 1916 German silent comedy film directed by Ernst Lubitsch and starring Lubitsch, Else Kentner and Guido Herzfeld. In English it is sometimes known by the alternative titles Shoe Salon Pinkus and The Shoe Palace. It was part of the Sally series of films featuring Lubitsch as a sharp young Berliner of Jewish heritage. After leaving school, a self-confident young man goes to work in a shoe shop. Soon after, he becomes a shoe tycoon.
Document 3: Heinrich Mann: Born in Lübeck, as the oldest child of Senator Thomas Johann Heinrich Mann, grain merchant and finance minister of the Free City of Lübeck, a state of the German Empire, and Júlia da Silva Bruhns. He was the elder brother of novelist Thomas Mann. The Mann family was an affluent family of grain merchants of the Hanseatic city of Lübeck. After the death of his father, his mother relocated the family to Munich, where Heinrich began his career as a "freier Schriftsteller" (free novelist).
Document 4: Industrial Revolution: The precise start and end of the Industrial Revolution is still debated among historians, as is the pace of economic and social changes. Eric Hobsbawm held that the Industrial Revolution began in Britain in the 1780s and was not fully felt until the 1830s or 1840s, while T.S. Ashton held that it occurred roughly between 1760 and 1830. Rapid industrialization first began in Britain, starting with mechanized spinning in the 1780s, with high rates of growth in steam power and iron production occurring after 1800. Mechanized textile production spread from Great Britain to continental Europe and the United States in the early 19th century, with important centres of textiles, iron and coal emerging in Belgium and the United States and later textiles in France.
Document 5: East Prussia: Through publicly funded emergency relief programs concentrating on agricultural land-improvement projects and road construction, the "Erich Koch Plan" for East Prussia allegedly made the province free of unemployment; on August 16, 1933 Koch reported to Hitler that unemployment had been banished entirely from East Prussia, a feat that gained admiration throughout the Reich. Koch's industrialization plans led him into conflict with R. Walther Darré, who held the office of the Reich Peasant Leader (Reichsbauernführer) and Minister of Agriculture. Darré, a neopaganist rural romantic, wanted to enforce his vision of an agricultural East Prussia. When his "Land" representatives challenged Koch's plans, Koch had them arrested.
Document 6: Edmund Landau: Edmund Landau was born to a Jewish family in Berlin. His father was Leopold Landau, a gynecologist and his mother was Johanna Jacoby. Landau studied mathematics at the University of Berlin, receiving his doctorate in 1899 and his habilitation (the post-doctoral qualification required in German universities) in 1901. His doctoral thesis was 14 pages long.
Document 7: Liselotte Herrmann: Born in Berlin, Liselotte Herrmann, an engineer’s daughter, had a middle class liberal upbringing. After completing her "Abitur" exams in 1929, she went to work as a laboratory assistant in a chemical factory to prepare her studies in chemistry. Later that year, her family moved to Stuttgart, where she attended the Technical College. In 1931, she switched to biology, studying at the Humboldt University in Berlin.
Document 8: Arnold Genthe: Arnold Genthe was born in Berlin, Prussia, to Luise Zober and Hermann Genthe, a professor of Latin and Greek at the Graues Kloster (Grey Monastery) in Berlin. Genthe followed in his father's footsteps, becoming a classically trained scholar; he received a doctorate in philology in 1894 from the University of Jena, where he knew artist Adolf Menzel, his mother's cousin.
Document 9: Industrial Revolution: The Industrial Revolution was the transition to new manufacturing processes in the period from about 1760 to sometime between 1820 and 1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power, the development of machine tools and the rise of the factory system.
Document 10: Economic history of Germany: From the 1830s and 1840s, Prussia, Saxony, and other states reorganized agriculture, introducing sugar beets, turnips, and potatoes, yielding a higher level of food production that enabled a surplus rural population to move to industrial areas. The beginning of the industrial revolution in Germany came in the textile industry, and was facilitated by eliminating tariff barriers through the Zollverein, starting in 1834. The takeoff stage of economic development came with the railroad revolution in the 1840s, which opened up new markets for local products, created a pool of middle managers, increased the demand for engineers, architects and skilled machinists, and stimulated investments in coal and iron. The political decisions about the economy of Prussia (and after 1871, all of Germany) were largely controlled by a coalition of ``rye and iron '', that is the Junker landowners of the east and the heavy industry of the west.
Document 11: Ernst von Possart: Possart was born in Berlin and was early an actor at Breslau, Bern, and Hamburg. Connected with the Munich Court Theatre after 1864, he became the oberregisseur in 1875. In 1877 he was made director of the Bavarian royal theatres; from 1887 to 1892 toured the United States, Germany, Russia, and The Netherlands; in 1895 to 1905 was general director of the Bayerische Hoftheater; and in 1901 opened the Prinzregententheater (Prince Regent's Theatre).
Document 12: Thuringia: Mining was important in Thuringia since the later Middle Ages, especially within the mining towns of the Thuringian Forest such as Schmalkalden, Suhl and Ilmenau. Following the industrial revolution, the old iron, copper and silver mines declined because the competition from imported metal was too strong. On the other hand, the late 19th century brought new types of mines to Thuringia: the lignite surface mining around Meuselwitz near Altenburg in the east of the Land started in the 1870s, and two potash mining districts were established around 1900. These are the Südharzrevier in the north of the state, between Bischofferode in the west and Roßleben in the east with Sondershausen at its centre, and the Werrarevier on the Hessian border around Vacha and Bad Salzungen in the west. Together, they accounted for a significant part of the world's potash production in the mid-20th century. After the reunification, the Südharzrevier was abandoned, whereas K+S took over the mines in the Werrarevier. Between 1950 and 1990, uranium mining was also important to cover the Soviet Union's need for this metal. The centre was Ronneburg near Gera in eastern Thuringia and the operating company Wismut was under direct Soviet control.
Document 13: Ernst Lubitsch: Ernst Lubitsch was born on January 29, 1892 in Berlin, Germany, the son of Anna (née Lindenstaedt) and Simon Lubitsch (), a tailor. His family was Ashkenazi Jewish, his father born in Grodno in the Russian Empire and his mother from Wriezen (Oder), outside Berlin. He turned his back on his father's tailoring business to enter the theater, and by 1911, he was a member of Max Reinhardt's Deutsches Theater.
Document 14: Textile manufacture during the British Industrial Revolution: Textile manufacture during the Industrial Revolution in Britain was centred in south Lancashire and the towns on both sides of the Pennines. In Germany it was concentrated in the Wupper Valley, Ruhr Region and Upper Silesia, while in the United States it was in New England. The four key drivers of the Industrial Revolution were textile manufacturing, iron founding, steam power and cheap labour.
Document 15: Unification of Germany: Historians debate whether Otto von Bismarck -- Minister President of Prussia -- had a master plan to expand the North German Confederation of 1866 to include the remaining independent German states into a single entity or simply to expand the power of the Kingdom of Prussia. They conclude that factors in addition to the strength of Bismarck's Realpolitik led a collection of early modern polities to reorganize political, economic, military, and diplomatic relationships in the 19th century. Reaction to Danish and French nationalism provided foci for expressions of German unity. Military successes -- especially those of Prussia -- in three regional wars generated enthusiasm and pride that politicians could harness to promote unification. This experience echoed the memory of mutual accomplishment in the Napoleonic Wars, particularly in the War of Liberation of 1813 -- 14. By establishing a Germany without Austria, the political and administrative unification in 1871 at least temporarily solved the problem of dualism.
