Hungary–Ukraine border

A short border across the northeastern corner of the Hungarian Plain along the Tisza, cutting off Zakarpattia, a region that has belonged to Hungary, Czechoslovakia and the Soviet Union before Ukraine. More than 100,000 ethnic Hungarians live just across it, and their language rights have become a running dispute between Budapest and Kyiv.

Ruthenia’s many owners

Before the First World War the area was part of the Kingdom of Hungary, and the valleys of Ruthenia, now Zakarpattia, ran down toward the Hungarian Plain. The Trianon treaty of 1920 gave Ruthenia to Czechoslovakia, so this line began as part of the Czechoslovak–Hungarian border. The Vienna Award of 1938 moved it, an agreement in Moscow in 1945 transferred Ruthenia from Czechoslovakia to the Soviet Union, and the 1947 peace treaty confirmed the result.[1]

The border crosses the flat plain of the middle Tisza, with its braided channels, ox-bow lakes and villages strung along the valley, while the wooded Carpathians rise to the north.[1]

Language and politics

More than 100,000 ethnic Hungarians live in Zakarpattia. In 2017 Kyiv passed an education law making Ukrainian the main language of teaching after primary school; Ukraine defended its language laws as essential to state cohesion and protection from Russian influence, while Budapest said Hungarian-language education was being restricted. An academic interviewed by Al Jazeera said the concerns were real but had been politicised since 2022, with Hungary using them as a veto on Ukraine’s EU path. Young people in the region told Al Jazeera the tensions were not felt on the ground.[2]

“I have friends in Hungary and friends in Ukraine; it has never been an issue for me”[2]
