[11] In the middle of the 18th century, during the Habsburg rule, the process of immigration of the East Slavic population to the area of the then southern Hungary (now Vojvodina, Serbia) began.

A part of the population that moved to the Habsburg monarchy after the abolition of the regional self-government in Zaporizhzhia (1775), settled around 1785 in the southern Hungarian areas, and mostly in the Banat Potisje.

Although part of that population later returned to their old homeland, during the 19th century there were occasional arrivals of new immigrants, among whom the awareness of the origin from the Ukrainian territory was preserved.

[12] At that time, the national development of the non-Hungarian peoples in Hungary was hampered by the state authorities, who promoted the policy of magyarization.

According to the practice of that time, the Austro-Hungarian authorities classified the entire East Slavic population under the term Ruthenians (Ruthenen).

[13] The Ukrainian idea also influenced some Carpathian Rusyns, and among the Rusyn leaders from the southern Hungarian regions who joined the Ukrainian national movement in the early 20th century was the Greek Catholic priest Havryyil Kostelnyk, a native of Ruski Krstur.

The activities of Ukrainian political immigrants were marked by frequent disputes with influential Russian political immigrants, which indirectly affected the situation among local Ukrainians, and relations within the wider East Slavic community in Yugoslavia became even more complex due to some specific processes among the local Rusyns.

[18][19] A significant turning point in the history of the Ukrainian community in Serbia occurred in 1990, when the representatives of Ukrainians in the former Yugoslavia reached an agreement with the pro-Ukrainian part of the Rusyns, which led to the creation of a joint organization called the Alliance of Rusyns-Ukrainian.

Over time, the pro-Ukrainian part of the Rusyn ethnicity was fully integrated into the Ukrainian national corps within the Alliance of Rusyn-Ukrainians.

[22] Although the activities of Ukrainian organizations in Serbia are primarily aimed at developing their own national community, without challenging and endangering the equal rights of other minority communities, in some Ukrainian circles there are occasional tendencies to deny the ethnic identity of Rusyns.
