Istvn Dobi was a Hungarian politician who was the Prime Minister of Hungary from 1948 to 1952. He was the first Communist to hold the post, joining the party shortly after it seized full control of the country in 1949.
Dobi originated from a poor peasant family and was born in Szny, Hungary. He finished primary school and in 1916 came into contact with the peasant movement. He supported the Hungarian Soviet Republic and in 1919 he was imprisoned for the first time. Upon his release, he was active in peasant and social democratic politics from the early 1920s and under police surveillance for this. He later worked as a casual laborer and became a farmer by occupation. Although he was not a Communist, he was arrested several times during the regency of Mikls Horthy.
