Geography
Košařiska is located about 26 kilometres (16 mi) southeast of Frýdek-Místek and 37 km (23 mi) southeast of Ostrava. It lies in the historical region of Cieszyn Silesia, in the Moravian-Silesian Beskids mountain range. The highest point is the Ostrý mountain at 1,044 m (3,425 ft) above sea level, located on the northern municipal border. A notable mountain is also Kozubová at 981 metres (3,219 ft) on the southern border. The Kopytná brook flows through the municipality.
After Revolutions of 1848 in the Austrian Empire a modern municipal division was introduced in the re-established Austrian Silesia. The village as a municipality was subscribed to the political district of Cieszyn and the legal district of Jablunkov. According to the censuses conducted in 1880–1910 the population of the municipality dropped from 480 in 1880 to 471 in 1910 with a majority being native Polish-speakers (between 96.8% and 100%) accompanied by German-speaking people (at most 15 or 3.2% in 1880). In terms of religion in 1910 the majority were Protestants (87.7%), followed by Roman Catholics (12.9%).[5]
