When was Belgium established as a nation state?

In November 1830, a National Congress was established in Belgium to create a constitution for the new state. Fears of "mob rule" associated with republicanism after the French Revolution of 1789, as well as the example of the recent, liberal July Revolution in France, led the Congress to decide that Belgium would be a popular, constitutional monarchy.

Belgium, officially the Kingdom of Belgium, is a state in Western Europe. The 1830 Belgian Revolution led to the establishment of an independent, Belgium under a provisional government and a national congress. Since the installation of Leopold I as king in 1831, Belgium has been a constitutional monarchy and parliamentary democracy.

In the early years of the Hundred Years' War, Edward III allied with the nobles of the Low Countries and the burghers of Flanders against France. 
Belgium established its independence in the revolution of 1830. Like the other European Great Powers, Britain was slow to recognise the new state. Even the election of Leopold of Saxe-Coburg, former son-in-law of Britain's King George IV and uncle to the future Queen Victoria, as King of the Belgians failed to win diplomatic recognition from London. Belgium's emergence had caused the break-up of the United Kingdom of the Netherlands, one of several buffer states established after the end of the Napoleonic Wars as a check against future French expansion, and London feared this newly formed nation would be unable to survive hostile expansion by its neighbours. A British-organised European Congress produced the Treaty of London of 1839, whereby the Great Powers (and the Netherlands) all formally recognised the independence of Belgium, and (at Britain's insistence) guaranteed its neutrality.

Belgium is a classic example of a state that is not a nation state. The state was formed by secession from the United Kingdom of the Netherlands in 1830, whose neutrality and integrity was protected by the Treaty of London 1839; thus it served as a buffer state after the Napoleonic Wars between the European powers France, Prussia (after 1871 the German Empire) and the United Kingdom until World War I, when its neutrality was breached by the Germans. Currently, Belgium is divided between the Flemings in the north and the French-speaking or the German-speaking population in the south. The Flemish population in the north speaks Dutch, the Walloon population in the south speaks French or German. The Brussels population speaks French or Dutch.

Unlike the British constitutional system, in Belgium "the monarchy underwent a belated evolution" which came "after the establishment of the constitutional monarchical system" because, in 1830–1831, an independent state, parliamentary system and monarchy were established simultaneously. Hans Daalder, professor of political science at the Rijksuniversiteit Leiden wrote: "Did such simultaneous developments not result in a possible failure to lay down the limits of the royal prerogatives with some precision—which implied that the view of the King as the Keeper of the Nation, with rights and duties of its own, retained legitimacy?"

Diplomatic relations were started in 1825 when Mexico established consular relations with the Kingdom of the Netherlands. Belgium became independent in 1830, and in 1838, representatives were sent to Mexico. The first consulate-level representatives were sent to Mexico in 1842. In 1861, both nations signed a "Treaty of Friendship" thus formally establishing diplomatic relations.

When Belgium became independent, state archives services were established in each chef-lieu of the following provinces: Bruges (1834), Namur (1849), Arlon (1851), Hasselt (1869), Antwerp (1896) and Tournai (from 1834 to 1895). In 1964, four district repositories were opened: in Huy (closed since February 2008), Kortrijk, Ronse (closed since September 2010) and Tournai. Auxiliary repositories were opened in Saint-Hubert (1960) and Beveren (1964). The State Archives repository in Eupen was created in 1988 following the second state reform of Belgium. The State Archives repositories in Leuven (2001), Anderlecht (2002) and Louvain-la-Neuve (2009) were established following the splitting of the province of Brabant. The National Archives 2 - Joseph Cuvelier repository will be inaugurated soon.

However, this plan was rejected and Belgium was established as an essential buffer state to check the ambitions of France. Wallonia and Flanders were unified as one state under a German prince, Leopold I of Saxe-Coburg-Gotha. A historian of the Belgian revolution said that "in Belgium, there are parties and provinces, but no nation. Like a tent erected for one night, the new monarchy, after sheltering us from the tempest, will disappear without a trace."

The relations began in 1947 with Belgian involvement in the Commission of Three Nations, together with Australia and the United States, on resolving Indonesia-Dutch disputes regarding the Indonesian sovereignty. Subsequently, Belgium was among the first European nation that recognized Indonesia in 1949. In December 1949 Indonesia established a representative to the Kingdom of Belgium. In 1963, both nations agreed to upgrade the bilateral relations from representative level to the level of embassy. The mission of the Republic of Indonesia to the European Community was established on 18 August 1990 in Brussels.

On 26 August 1830, the day after the rioting at the Brussels Opera and the start of the Belgian Revolution, the flag of France flew from the city hall of Brussels. The insurgents hastily replaced it with a tricolour of red, yellow and black horizontal stripes (similar to the one used during the Brabant Revolution of 1789–1790 which had established the United States of Belgium) made at a nearby fabric store. As a result, Article 193 of the Constitution of Belgium describes the colours of the Belgian nation as "Red, Yellow and Black" instead of using the order shown in the official flag.
