The background to the war can be found in the 2010 Parliamentary elections in which the conservative party Fidesz under Viktor Orbán won the election with 52.73% of the votes and 263 of the seats (out of a total number of 386). A new citizenship law gained a majority in the National Assembly on 14th May which put huge strain on the two countries relations as the law allows ethnic Hungarians living in other countries (e.g. Slovakia) to apply for duel citizenship. In a tit-for-tat exchange, Slovakia retaliated later the same day with its own legislation threatening that anyone who applies for citizenship of another country will lose their Slovak citizenship. This was to come into effect sometime in July. Naturally, this only served to worsen the relations and increase tensions.
