Brussels was officially founded in 979 when a castle was built near the Senne River.
In the middle of the 11th century, city walls were built and Brussels grew throughout the Middle Ages due to its strategic location on the Bruges-Ghent-Cologne trade route.
After Brussels was attacked by French king Louis XIV in 1695, various foreign powers took control throughout the years. On July 21, 1831, Leopold I ascended to the throne, becoming Belgium’s first king and Brussels was named the capital of the new kingdom.
The new kingdom went through a phase of rebuilding, including the establishment of international congresses and scientific organizations. Foreign artists, philosophers, and scientist found their way to Brussels, including Karl Marx and Victor Hugo.
Brussels experienced significant damage during World War II but was able to recover and continue to develop in the following years. Belgium is currently split into three semi-independent regions: Flanders, Wallonia, and the Brussels-Capital Region. Brussels has become the “capital” of the European Union and NATO.
