The kingdom was succeeded by a Communist era (1947–1989) during which Hungary gained widespread international attention regarding the Revolution of 1956 and the seminal move of opening its border with Austria in 1989, thus accelerating the collapse of the Eastern Bloc. The present form of government is a parliamentary republic (since 1989). Today, Hungary is a high-income economy, and a regional leader regarding certain markers.
