Belgium is a small country located in Western Europe, with a history that spans many centuries. The region has been inhabited since prehistoric times and has been ruled by various different groups over the centuries.

• In the Roman era, the region that is now Belgium was known as "Gallia Belgica", and it became an important center of Roman civilization. During the Middle Ages, the country was part of the Holy Roman Empire, and it was ruled by a series of dukes and counts. In the late 14th century, the Burgundian dukes established a powerful duchy in the region.
• In the 16th century, the Southern Netherlands, present-day Belgium, came under the control of the Habsburgs and remained so until the late 18th century, at this time the country experienced a period of economic growth, but it was also the stage for religious and political conflicts between Catholic and Protestant, Flemish and Walloons.
• In 1830, Belgium declared its independence from the United Kingdom of the Netherlands and become a constitutional monarchy. The country experienced rapid industrialization and economic growth in the 19th century, which led to an increase in the standard of living and a growth in population.
• During World War I, Belgium was occupied by German forces. After the war, the country was granted a mandate to govern the former German colony of Rwanda-Urundi, present-day Rwanda and Burundi, by the League of Nations. During World War II, Belgium was occupied by Nazi Germany, but it was liberated by the Allies in 1944.
