Belgium is the heir of several former Medieval powers, and you will see traces of these everywhere during your trip in this country.
After the collapse of the Carolingian Empire in the 9th century, the territory that is nowadays Belgium, Netherlands, and Luxembourg, was part of Lotharingia, an ephemerous kingdom soon to be absorded into the Germanic Empire; however, the special character of "Lower Lotharingia" remained intact in the feudal Empire : this is the origin of the Low Countries, a general term that encompasses present-day Belgium, Netherlands, and Luxembourg.
The widely autonomous fiefdoms of the Low Countries were amongst the richest places in Medieval Europe and you will see traces of this past wealth in the rich buildings of Bruges, Brussels, Antwerp, Ghent, Leuven, Tournai, Mons, etc. These cities progressively fell under the control of a powerful and ambitious family : the Dukes of Burgundy. The whole realm of the dukes extended from the Low Countries to the borders of Switzerland. Using wealth, strategy, and alliances, the Dukes of Burgundy aimed at reconstituting Lotharingia. The death of the last Duke, Charles the Bold, put an end to this dream. However, the treasures of the Dukes of Burgundy remains as a testimony of their rules in Belgian museums and landmarks.
The powerful Habsburg family then inherited from the Low Countries. Reformation is the reason that Belgium and Netherlands were first put apart: the northern half of the Low Countries embraced Protestantism and rebelled against the Habsburg rule, while the southern half remained faithful to both its ruler and the Catholic faith. These two halves roughly corresponds to present-day Belgium and Netherlands.
Belgium was called Austrian Netherlands, then Spanish Netherlands, depending on which branch of the Habsburg ruled it. The powerful German emperor and Spanish king, Charles V, was born in the Belgian city of Ghent and ruled from Brussels. Many places in Belgium are named after him, including the city of Charleroi and even a brand of beer. Every year, the Brusselers emulates his first parade in their city in what is called the Ommegang.
Belgium was briefly a part of the Napoleonic Empire. After Napoleon's defeat, a large Kingdom of the Netherlands was created, comprising the whole of the Low Countries. However, the religious opposition still remained and the split was aggravated by political differences between Belgian liberals and Dutch aristocrats. Belgium became independent from the Netherlands in 1830 after a short revolution and a war against the Netherlands.
It was occupied by Germany during World Wars I and II and has many war graves near the battle zones, most of them are around Ieper in English archaically rendered as Ypres, with Yperite another name for mustard gas due to intensive use there in WWI. It has prospered in the past half century as a modern, technologically advanced European state and member of NATO and the EU. Tensions between the Dutch-speaking Flemings of the north and the French-speaking Walloons of the south have led in recent years to constitutional amendments granting these regions formal recognition and autonomy.
