During the second half of the 18th century and first half of the 19th century Slovak and Rusyn people moved from Slovakia to the plains of Banat and Arad, the uplands of Bihor and Salaj, also the plains and mining towns of Satu Mare and Maramureş.
Slovaks were brought in as miners and mostly were subsequently absorbed into the Hungarian or German populations of the mining areas. Many Slovaks have in the 20th century emigrated to the USA and Canada.
