In 1458 under Bohemian rule the area around Kłodzko became a county . In 1742 it was conquered by Prussia . In 1816 the county was abolished , and the territory was reformed into the '' Landkreis Glatz '' of Prussian Silesia After World War I the new Czechoslovak state laid claim to the County of Kladsko . Each one of the proposals put forth by the Czechoslovak delegation included annexing the Czech Corner to Czechoslovakia . These claims were however ultimately rejected by the 1919 Treaty of Versailles . With the implementation of the Oder-Neisse line at the Potsdam Conference in 1945 , most of the territory of Prussian Silesia including both Kłodzko , referred to as " Little Prague " ( ) and the Czech Corner became part of the Republic of Poland . Kłodzko land again became the focus of an attempt to reincorporate the area into Czechoslovakia , one of several Polish – Czechoslovak border conflicts when in May 1945 Czechoslovakia tried to annex the area on behalf of the Czech minority present in the Czech Corner . Pressure brought on by the Soviet Union ultimately led to a ceasing of military operations
