The Hungarian minority of Romania (romániai magyarok; maghiarii din România) is the largest ethnic minority in Romania. As per the 2021 Romanian census, 1,150,154 people (6% of respondents) declared themselves Hungarian, while 1,182,154 people (6.3% of respondents) stated that Hungarian was their mother tongue.
Most ethnic Hungarians of Romania live in areas that were, before the 1920 Treaty of Trianon, parts of Hungary. Encompassed in a region known as Transylvania, the most prominent of these areas is known generally as Székely Land (Ținutul Secuiesc; Székelyföld), where Hungarians comprise the majority of the population. Transylvania, in the larger sense, also includes the historic regions of Banat, Crișana and Maramureș. There are forty-one counties of Romania; Hungarians form a large majority of the population in the counties of Harghita (85.21%) and Covasna (73.74%), and a large percentage in Mureș (38.09%), Satu Mare (34.65%), Bihor (25.27%), Sălaj (23.35%), and Cluj (15.93%) counties.
There also is a community of Hungarians living mostly in Moldavia, known as the Csángós. These live in the so-called region of Csángó Land in Moldavia but also in parts of Transylvania and in a village of Northern Dobruja known as Oituz. In addition, sparse populations of Székelys are to be found across southern Bukovina, inhabiting several villages and communes in Suceava County. Aside from the aforementioned historical regions of Romania, Bucharest was also home in the past and still is to a sizable Hungarian-Romanian community.
History of Transylvania
The Hungarian tribes originated in the vicinity of the Ural Mountains and arrived in the territory formed by present-day Romania during the 9th century from Etelköz or Atelkuzu (roughly the space occupied by the present day Southern Ukraine, the Republic of Moldova and the Romanian province of Moldavia). Due to various circumstances (see Honfoglalás), the Magyar tribes crossed the Carpathians around 895 AD and occupied the Carpathian Basin (including present-day Transylvania) without significant resistance from the local populace.
