The Slavic Congress opens in Prague.

The Prague Slavic Congress of 1848 took place in Prague, Austrian Empire between 2 June and 12 June 1848. It was the first occasion on which representatives from nearly all Slav populations of Europe met in one place to discuss the emerging idea of Pan-Slavism. The delegates at the Congress were not only anti-Austrian, but also anti-Russian, despite the latter being the only fully independent Slavic nation at the time.

Prague is the capital and largest city of the Czech Republic and the historical capital of Bohemia. Prague, located on the Vltava River, has a population of about 1.4 million, while its metropolitan area is home to approximately 2.3 million people.

June 2 is the 153rd day of the year in the Gregorian calendar; 212 days remain until the end of the year.
