What did Slovakia Hungary dispute over?

The Slovakia-Hungary dispute primarily revolves around issues of nationalism, historical grievances, and minority rights, particularly regarding the Hungarian minority in Slovakia. Tensions have been exacerbated by differing interpretations of historical events, such as the post-World War I Treaty of Trianon, which greatly reduced Hungary's territory and population. Additionally, disputes have arisen over language laws and cultural rights for ethnic Hungarians in Slovakia, leading to diplomatic friction between the two countries.
