1363/5000 Between 1954 and 1957, he was a deputy lieutenant (he was deprived of his rank in 1956). In 1956 he was the secretary of the Debrecen Kossuth Circle and the Revolutionary Committee of the Hajdú-Bihar County Revolution. He contributed to the formulation of revolutionary demands in Debrecen and he handed them over to the government. After the Revolution was overthrown, he was interned for a short time. He lost his assistantship at the Kossuth Lajos University in 1956 because of his role in 1956, and his research career was stalled. He emigrated to France in 1957, but returned home a few months later. He had no job until 1958 and then worked in a large library of the Reformed College in Debrecen until 1961, after which he was employed for a short period of time. Until 1963 he was a primary school teacher in Dabason and Pestújhely.
