Hungary under Horthy was characterized by its conservative, nationalist and fiercely anti-communist character. The government was based on an unstable alliance of conservatives and right-wingers. Foreign policy was characterized by revisionism - the total or partial revision of the Treaty of Trianon, which had seen Hungary lose over 70% of its historic territory along with over three million Hungarians, who mostly lived in the border territories outside the new borders of the kingdom. Hungary's interwar politics were dominated by an obsession with the territorial losses suffered in this treaty.
