Flag of Silesia (Czech part)
'Czech Silesia', one of the three
Czech lands, is the Czech part of
Silesia. It is located in the north-east of the
Czech Republic. In the past it has also been known as 'Moravian Silesia' or, between
1918 and
1945, 'Sudeten Silesia'. Most of its land belonged to
Austrian Silesia before
1918.

Czech Silesia

Coat of arms of Czech Silesia.
The area lies to the east and west of the city of
Ostrava and comprises much of the modern
Moravian-Silesian Region and, in its far west, a small part of the
Olomouc Region around the city of
Jeseník. After Ostrava, the most important cities are
Opava and
Český Těšín, that part of the border city of
Cieszyn which lies within the
Czech Republic.
It is situated in the
Sudetes mountains which become the
Carpathians in the east. Its major rivers are the
Oder,
Opava and
Olše (which forms part of the border with
Poland).
History
Modern-day Czech Silesia is mainly that small part of Silesia that remained within
Austria at the end of the First Silesian War (see
War of the Austrian Succession) in
1742, when the rest of Silesia was ceded to
Prussia. It was organised as the 'Duchy of Upper and Lower Silesia' with its capital at Opava (in
German, ''Troppau''). In
1900, the
Duchy occupied an area of 5140 km² and had a population of 670,000.
In
1918, the former Duchy formed part of the
Sudetenland Province of
German Austria along with northern
Moravia, but under the
Treaty of Saint Germain of
1919, it fell largely to the newly-created state of
Czechoslovakia with the exception of land east of the River
Olza around
Cieszyn which became part of
Poland.
Hlučínsko (in
German ''Hultschiner Ländchen''), formerly part of
Prussian Silesia also became part of Czechoslovakia under the
Treaty of Versailles in
1920.
Following the
Munich Agreement of
1938, most of Czech Silesia became part of the
Reichsgau Sudetenland, although Hlučínsko was re-unified with
Prussia and Poland took more land in (
Cieszyn Silesia) on the west bank of the Olza. (The Polish gains being lost when
Germany occupied Poland the following year).
With the exception of the areas around Cieszyn and Ostrava, Czech Silesia was predominantly settled by ethnic Germans up until 1945. Following the
Second World War, the Sudetenland and Hlučínsko were returned to Czechoslovakia and the German-speaking population was expelled (see
Expulsion of Germans after World War II). The border with Poland was once again set along the Olza (although this was not confirmed by treaty until 1958).
People
Some of the native
Slavic population speak
Lach, which is classed by
Ethnologue as a dialect of
Czech [1], although it also shows some similarities to
Polish. In Cieszyn Silesia the
Cieszyn Silesian dialect is also spoken, mostly by members of the
Polish minority (see:
Zaolzie).
