Debrecen is a city located in Hungary and serves as the regional center of the Northern Great Plain region. It is the seat of Hajdú-Bihar County and holds status as a city with county rights. As Hungary's second-largest city after Budapest, it was historically significant as the largest Hungarian city during the 18th century.
