Silesia: Modern Silesia

During the Industrial Revolution of the late 18th and 19th cent. textile weaving and coal mining developed rapidly in Silesia, but industrialization brought great social tension. The Silesian weavers became dependent on entrepreneurs who farmed out work; working conditions and unemployment became intolerable, and discontent ran high. Most coal mining was in the hands of private industry, under which miners were often mistreated. Landholding conditions also were iniquitous, most of the land being held by owners of large estates. The resulting tensions assumed an ethnic character, since the upper and middle classes were predominantly German, while a large percentage of the workers were Polish. Though these conditions were gradually improved, Silesia even in the 20th cent. remained, despite its great productivity, a relatively backward area.

After World War I the Treaty of Versailles (1919) provided for a plebiscite to determine if Upper Silesia was to remain German or to pass to Poland. The results of the plebiscite (1921) were favorable to Germany except in the easternmost part of Upper Silesia, where the Polish population predominated. After an armed rising of the Poles (1922) the League of Nations accepted a partition of the territory; the larger part of the industrial district, including Katowice, passed to Poland. The contested city and district of Teschen were partitioned in 1920 between Poland and Czechoslovakia (to the satisfaction of neither) by the conference of ambassadors. The political division of the Silesian industrial district was carried out so arbitrarily that the boundaries often cut through mines; some workers slept in one country and worked in another. As a result of the Munich Pact of 1938 most of Czech Silesia was partitioned between Germany and Poland, and after the German conquest of Poland in 1939 all Polish Silesia was annexed to Germany.

After World War II the pre-1938 boundaries were restored, but all formerly Prussian Silesia E of the Lusatian Neisse was placed under Polish administration (a small section of Lower Silesia W of the Neisse was incorporated with the East German state of Saxony). The Allies also allowed the expulsion (in an “orderly and humane” manner) of the German population from Czech Silesia, Polish Silesia, and Polish-administered Silesia. The mass expulsion of Germans was, perforce, neither orderly nor humane; moreover, although the transfer of territories to Polish administration was made subject to revision in a final peace treaty with Germany, the Polish government treated all Silesia as integral Polish territory. West Germany finally relinquished all claims to the area under the terms of a nonaggression pact with Poland in 1972. With the unification of East and West Germany in 1990, German leaders attempted once again to allay the fears of its neighbors, particularly Poland, by declaring the stability of the borders determined at the end of World War II.
