It is the country's principal political, cultural, commercial, industrial, and transportation centre. Budapest became a single city occupying both banks of the river Danube with its unification on 17 November 1873 of Buda and Óbuda, on the west bank, with Pest, on the east bank. The history of Budapest began with Aquincum, originally a Celtic settlement that became the Roman capital of Pannonia Inferior. Hungarians arrived in the territory in the 9th century. Following the Battle of Mohács and nearly 150 years of Ottoman rule, the region entered a new age of prosperity in the 18th and 19th centuries, and Budapest became a global city after its unification in 1873. It also became the second capital of the Austro-Hungarian Empire, a great power that dissolved in 1918, following World War I. Budapest was the focal point of the Hungarian Revolution of 1848, the Hungarian Republic of Councils of 1919, Operation Panzerfaust in 1944, the Battle of Budapest in 1945, and the Revolution of 1956)
