The Slovak volunteers units were a reactionary armed movement opposed to the Hungarian Revolution. Organized in the Western parts of modern Slovakia, the volunteers led multiple campaign across majority Slovak areas in Upper Hungary, all the way to Kassa (Košice) in the east. The leaders of the Slovak Volunteers, Ľudovít Štúr, Jozef Miloslav Hurban and Michal Miloslav Hodža, struggled to elicit total support from the Slovak nation. Many Slovak peasants were more concerned with the abolition of feudal servitude, and not with wider national goals. Religious differences also played a key role, as the leaders of the Slovak volunteers were predominantly protestant, which led to difficulties in eliciting support in regions with a catholic Slovak majority. As a result, they could recruit only up to 2000 people, while a much higher percentage of the Slovak population was serving in the Hungarian Honvédség (Home Guard) among the Hungarian revolutionaries.
