Dissolution of Czechoslovakia
The Dissolution of Czechoslovakia (, ), which took effect on 1 January 1993, was an event that saw the self-determined split of the federal state of Czechoslovakia into the Czech Republic and Slovakia, entities that had arisen before as the "Czech Socialist Republic" and the "Slovak Socialist Republic" in 1969 within the framework of a federal republic.
German Zone of Protection in Slovakia
The German Zone of Protection in Slovakia, or the Protective Zone () was an area established in the western parts of the First Slovak Republic after the dissolution and division of Czechoslovakia by Nazi Germany during 1939. The special status of the zone was already created in the initial German-Slovak treaty of 23 March 1939, which defined the protective relationship between Germany and the Slovak State. The zone was codified by the German-Slovak treaty of August 28, 1939, which was signed in Bratislava ().
