Trianon100: maps of public spaces in Hungary named after settlements in the detached territories

For the 100th anniversary of the Treaty of Trianon, we created interactive maps of Hungarian public spaces that were named after the settlements in the territories detached from the former Kingdom of Hungary in 1920. A small part of these public spaces were already named after these settlements before the Treaty of Trianon, but most of them were named or renamed between the two world wars, or after 1990.

On the first interactive, zoomable map, you can see public spaces and the settlements they were named after at the same time. Public spaces and corresponding settlements are colored by country. The size of the settlements shows how many public areas are named after them in Hungary.

We also made special map details of those parts of some cities where there are spectacularly many public areas named after the lost settlements. These include Székesfehérvár, where the streets of Öreghegy and Maroshegy garden city parts all have such names, or the outskirts of Budapest, the Szemeretelep in Pestszentlőrinc, the garden city part next to the Havanna housing estate in Kispest, and the streets of Kossuthfalva, which were named after the lost settlements from the mid-1920s onward.

In the second map, we connected the settlements in the detached territories with the settlements in Hungary where the given public areas are located by colored lines by country.

Lost settlements with the most Hungarian street names are also depicted in a separate visualization:

452 settlements in the former Kingdom of Hungary have become street names and names of public spaces in Hungary. Most of the streets and squares were named after Arad (128) and Kolozsvár (Cluj-Napoca, 121), followed by Pozsony (Bratislava, 98) and Kassa (Košice, 93). Szabadka (Subotica, 44) from Serbia, Ungvár (Uzhgorod, 26) from Ukraine, Fiume (Rijeka, 25) from Croatia, and Kismarton (Eisenstadt, 12) from Austria gave the most public names.

Határon túli utcanevek Magyarországon

Magyarországon jelenleg több mint 2100 közterület (út, utca, tér, sétány, köz, stb.) viseli határon túli, egykor a Magyar Királysághoz tartozó település nevét. Ezeknek a közterületeknek egy kisebbik részét természetesen már Trianon előtt is ezekről a településekről nevezték el, ám többségüket a két világháború között, vagy a rendszerváltás után nevezték át róluk, illetve a települések bővülésekor, új lakóövezetek, telepek építésekor kapták a nevüket. Ebben az anyagban azt mutatjuk be interaktív térképeken és adatvizualizációkon, hogy mely határon túli településekről elnevezett köztereink hol vannak és milyen mintázatot rajzolnak ki.

Interactive map: see the movement of Hungarian migrants and refugees after the Treaty of Trianon

István Dékány has recently published the online database that accompanies his book titled Orphans of Trianon (Trianoni árvák). The database contains data about Hungarians who were either deported from their homeland or who fled their homes after the Treaty of Trianon was signed in 1920.

Interactive feature – native language ethnic map of historical Hungary in 1910

After creating a map of the ethnic and the religious composition of Hungary based on the 2011 Census, now we’ve made an interactive version of the native-language ethnic data of the 1910 Census. The geoinformatic data for the administrative boundaries of the municipalities in .shp extension come from the GISta Hungarorum project’s site.
