Hungary–Poland relations

Poland–Hungary relations are the foreign relations between Poland and Hungary. Relations between the two nations date back to the Middle Ages. The two Central European people have traditionally enjoyed a very close friendship, brotherhood and camaraderie rooted in a deep history of shared rulers, cultures, struggles, and faith. Both countries commemorate their fraternal relationship on 23 March.

From 1370 to 1382 the Kingdom of Poland and Kingdom of Hungary entered into a personal union and were ruled by the same King, Louis the Great. This period in Polish history is sometimes known as the Andegawen Poland. Louis inherited the Polish throne from his maternal uncle Casimir III. After Louis's death the Polish nobles (the szlachta) decided to end the personal union, since they did not want to be governed from Hungary, and chose Louis's younger daughter Jadwiga as their new ruler, while Hungary was inherited by his elder daughter Mary. A second personal union with Poland was formed for the second time from 1440 to 1444, when King Władysław III of Poland was also King of Hungary.

Both countries are full members of NATO, joining it on the same day (March 12, 1999) and are also both members of the European Union, the OECD, the Council of Europe, the Visegrád Four (along with Slovakia and the Czech Republic), the Bucharest Nine, the Three Seas Initiative, the OSCE and the World Trade Organization.

The leaders of the two countries have been holding regular secret meetings to improve bilateral relations and work more closely together. Hungarian-Polish political scientist Dominik Hejj states: "The relations are very strong, and almost every week a Polish minister visits Hungary and vice versa". The two countries first joined NATO in 1999 and then the European Union in 2004.
