Important ethnographic map of Hungary after the Treaty of Trianon

A large-format ethnographic and statistical map of the historical Kingdom of Hungary, designed by geographer Károly Kogutowicz and issued in this Italian-language edition amid Hungary's international treaty-revision campaign of the late 1920s, sparked in part by Lord Rothermere's 1927 Daily Mail article "Hungary's Place in the Sun." Kogutowicz had been part of the team that produced the original 1918 ethnographic survey underlying Pál Teleki's "Carte Rouge," used by the Hungarian delegation at the Paris Peace Conference; this later map applies the same method to argue for revision of the 1920 Treaty of Trianon. Eleven ethnic groups are distinguished by colour: Magyars (red), Germans (orange), Slovaks (green), Ruthenians (brown), Poles (blue), Romanians (lilac), Serbs (yellow), Croats (mid-blue), Slovenes/"Vends" (tan), Bosniaks/Bunjevci (stippled), and other (grey), with density rendered through varying dot and block sizes. A black-and-white banded line marks the post-Trianon frontier, distinguished in the key from ordinary national and county borders. Marginal text and pie charts compare territory and population ceded to Czechoslovakia, Romania, and Yugoslavia against each successor state's own claimed ethnic majority, alongside a comparison of Hungary's territorial and demographic losses against Germany's under Versailles.
