Following a Celtic (after c. 450 BC) and a Roman (9 BC – c. 430) period, the foundation of Hungary was laid in the late 9th century by theHungarian ruler Árpád, whose great-grandson Stephen I of Hungary was crowned with a crown sent from Rome by the pope in 1000. After being recognized as a kingdom, Hungary remained a monarchy for 946 years,[note 2] and at various points was regarded as one of the culturalcenters of the Western world. A significant power until the end of World War I, Hungary lost over 70% of its territory, along with 3.3 million people of Hungarian ethnicity, under the Treaty of Trianon, the terms of which have been considered excessively harsh by many in Hungary. The country lost eight of its ten biggest Hungarian cities as well. 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.In the past decade, Hungary was listed as one of the 15 most popular tourist destinations in the world. The country is home to the largest thermal water cave system and the second largest thermal lake in the world (Lake Hévíz), the largest lake in Central Europe (Lake Balaton), and the largest natural grasslands in Europe (Hortobágy).
