Wine production occurs in both Wallonia and Flanders.
As French is one of Belgium's official languages, the official terms used for Belgian wine regions are the same as those for French wine.
Belgium has five officially demarcated "Appellations d'origine contrôlées" (AOCs), four in Flanders and one in Wallonia, and two "Vin de pays" regions.
Hageland, situated in Flemish Brabant close to Leuven, was the first AOC was created, in 1997.
AOC Haspengouw (Hesbaye) followed in 2000, located in Limburg, close to the border with Netherlands, and home to Belgium's most famous "château" and largest wine producer, "Wijnkasteel Genoels-Elderen".
AOC Heuvelland followed in 2005.
In Dutch, these three Flemish AOCs are written as "Hagelandse wijn", "Haspengouwse wijn" and "Heuvellandse wijn", respectively, and the official term corresponding to the French term AOC is "Gecontroleerde oorsprongsbenaming".
There is also an AOC for quality sparkling wine from Flanders, "Vlaamse mousserende kwaliteitswijn", created in 2005.
The first Wallonian AOC, Côtes de Sambre et Meuse, was created in 2004, and is situated between the rivers Sambre and Meuse, in the vicinity of Liège.
The two "Vin de Pays" (country wine) regions cover Flanders and Wallonia, respectively.
The Flemish country wine is simply designated "Vlaamse landwijn", while the Wallonian country wine carries the slightly more fanciful name "Vin de pays des Jardins de Wallonie". 
Since 23 April 1993, Belgium has been a federal state, divided into three geographical regions and three linguistic communities.
The Walloon Region is one of the three regions, almost totally French-speaking.
The other two geographical regions are the Flemish Region, a mainly Dutch-speaking region in the north and west, and the Brussels-Capital, bilingual French-Dutch administering the city of Brussels.
Some governmental competencies are exercised by the linguistic communities, of which the French community of Belgium is the largest in Wallonia, while the German-speaking community of Belgium's responsibilities are for an area within Wallonia.
The Parliament of Wallonia is a unicameral legislature of 75 members elected to serve five-year terms.
It is based in the former Hospice Saint-Gilles at Namur.
The Government of Wallonia is responsible to the Parliament.
Excepting cultural and education matters, which are controlled by the linguistic communities, the Walloon Region's competences include local administration, housing, transport, training, employment, health and social policy.
The region administers a number of companies, including those responsible for the provision of water and public transport.
The constitutional system of Belgium grants the Walloon Region its own legislative and executive powers in the fields for which it is competent: agriculture and rural renewal development of the territory and town planning economy and foreign trade employment and vocational training the environment, water and nature conservation housing local authorities, subsidized works and sports infrastructures scientific research, new technologies and energy international relations health and social affairs tourism and heritage regional transport, mobility and public works.  
Belgium has three main geographical regions: the coastal plain in the north-west, the central plateau, and the Ardennes uplands in the south-east.
The coastal plain consists mainly of sand dunes and polders.
Polders are areas of land, close to or below sea level that have been reclaimed from the sea, from which they are protected by dikes or, further inland, by fields that have been drained with canals.
The second geographical region, the central plateau, lies further inland.
This is a smooth, slowly rising area that has many fertile valleys and is irrigated by many waterways.
Here one can also find rougher land, including caves and small gorges.
The third geographical region, called the Ardennes, is more rugged than the first two.
It is a thickly forested plateau, very rocky and not very good for farming, which extends into northern France and in Germany where it is named Eifel.
This is where much of Belgium's wildlife can be found.
Belgium's highest point, the Signal de Botrange is located in this region at only .
Belgium has relatively few natural lakes, and none of any great size.
Notable natural regions include the Ardennes, Campine and High Fens. 
Belgium has an embassy in Ottawa, two consulates (in Montreal and Toronto), and four honorary consulates (in Edmonton, Halifax, Vancouver and Winnipeg) located in Canada.
Belgium's three regions (Wallonia, Flanders and Brussels) each have their own offices in the Montreal consulate.
Wallonia also has a second office in the Toronto consulate, which also represents Flanders and Brussels.
Canada maintains an embassy in Brussels (which also covers Luxembourg).
Canada also has a consulate in Antwerp, and Quebec maintains its own separate delegation in Brussels.
The Canadian delegations to the European Union and the North Atlantic Treaty Organization are located in Belgium, as Belgium houses the headquarters of each.
Luxembourg is often dealt with in tandem to Belgium.
Belgium and Canada are member states of a variety of international organizations.
They include: the United Nations, NATO, La Francophonie, the Organization for Security and Co-operation in Europe, and the Organization for Economic Cooperation and Development. 
Since the country's independence, Roman Catholicism, counterbalanced by strong freethought movements, has had an important role in Belgium's politics.
However Belgium is largely a secular country as the "laicist" constitution provides for freedom of religion, and the government generally respects this right in practice.
During the reigns of Albert I and Baudouin, the monarchy had a reputation of deeply rooted Catholicism.
Roman Catholicism has traditionally been Belgium's majority religion; being especially strong in Flanders.
However, by 2009 Sunday church attendance was 5% for Belgium in total; 3% in Brussels, and 5.4% in Flanders.
Church attendance in 2009 in Belgium was roughly half of the Sunday church attendance in 1998 (11% for the total of Belgium in 1998).
Despite the drop in church attendance, Catholic identity nevertheless remains an important part of Belgium's culture.
Symbolically and materially, the Roman Catholic Church remains in a favourable position.
Belgium has three officially recognized religions: Christianity (Catholic, Protestantism, Orthodoxy and Anglicanism), Islam and Judaism.
In the early 2000s there were approximately 42,000 Jews in Belgium.
The Jewish Community of Antwerp (numbering some 18,000) is one of the largest in Europe, and one of the last places in the world where Yiddish is the primary language of a large Jewish community (mirroring certain Orthodox and Hassidic communities in New York and Israel).
In addition most Jewish children in Antwerp receive a Jewish education.
There are several Jewish newspapers and more than 45 active synagogues (30 of which are in Antwerp) in the country.
A 2006 inquiry in Flanders, considered to be a more religious region than Wallonia, showed that 55% considered themselves religious and that 36% believed that God created the universe.
On the other hand, Wallonia has become one of Europe's most secular/least religious regions.
Most of the French-speaking region's population does not consider religion an important part of their lives, and as much as 45% of the population identifies as irreligious.
This is particularly the case in eastern Wallonia and areas along the French border.
A 2008 estimate found that 6% of the Belgian population, about 628,751, is Muslim (98% Sunni), while a 2011 estimate claims 1,000,000 inhabitants of Muslim background in the country.
Muslims constitute 30–35% of the population of Brussels, 4.0% of Wallonia and 3.9% of Flanders.
The majority of Belgian Muslims live in the major cities, such as Antwerp, Brussels and Charleroi.
The largest group of immigrants in Belgium are Moroccans, with 400,000 people.
The Turks are the third largest group, and the second largest Muslim ethnic group, numbering 220,000.
According to the Eurobarometer Poll in 2010, 37% of Belgian citizens responded that "they believe there is a God", whereas 31% answered that "they believe there is some sort of spirit or life force" and 27% that "they do not believe there is any sort of spirit, God, or life force".
