The Brussels Stock Exchange (French: Bourse de Bruxelles, Dutch: Beurs van Brussel), abbreviated to BSE, was founded in Brussels, Belgium, by decree of Napoleon in 1801. On 22 September 2000, the BSE merged with Paris Bourse, Lisbon Stock Exchange and the stock exchanges of Amsterdam, to form Euronext N.V., the first pan-European exchange for equities and derivatives, with common trading and clearing of all products, and was renamed Euronext Brussels. The most well known index on the Brussels Stock Exchange is the BEL20. It now belongs to the NYSE Euronext group, the first global stock exchange.
