Document 3: Belgium: Belgium, officially the Kingdom of Belgium, is a country in Western Europe bordered by France, the Netherlands, Germany and Luxembourg. A small and densely populated country, it covers an area of 30,528 square kilometres (11,787 sq mi) and has a population of more than 11 million. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch - speaking, mostly Flemish community, which constitutes about 59 percent of the population, and the French - speaking, mostly Walloon population, which comprises about 40 percent of all Belgians. Additionally, there is a small group of German speakers, numbering around one percent, who live in the East Cantons. The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi and Liège.

Document 6: Belgium: Belgium was the first continental European country to undergo the Industrial Revolution, in the early 19th century. Liège and Charleroi rapidly developed mining and steelmaking, which flourished until the mid-20th century in the Sambre and Meuse valley and made Belgium among one of the three most industrialized nations in the world from 1830 to 1910. However, by the 1840s the textile industry of Flanders was in severe crisis, and the region experienced famine from 1846 to 1850.After World War II, Ghent and Antwerp experienced a rapid expansion of the chemical and petroleum industries. The 1973 and 1979 oil crises sent the economy into a recession; it was particularly prolonged in Wallonia, where the steel industry had become less competitive and experienced serious decline. In the 1980s and 1990s, the economic center of the country continued to shift northwards and is now concentrated in the populous Flemish Diamond area.By the end of the 1980s, Belgian macroeconomic policies had resulted in a cumulative government debt of about 120% of GDP. As of 2006, the budget was balanced and public debt was equal to 90.30% of GDP. In 2005 and 2006, real GDP growth rates of 1.5% and 3.0%, respectively, were slightly above the average for the Euro area. Unemployment rates of 8.4% in 2005 and 8.2% in 2006 were close to the area average. By October 2010, this had grown to 8.5% compared to an average rate of 9.6% for the European Union as a whole (EU 27). From 1832 until 2002, Belgium's currency was the Belgian franc. Belgium switched to the euro in 2002, with the first sets of euro coins being minted in 1999. The standard Belgian euro coins designated for circulation show the portrait of the monarch (first King Albert II, since 2013 King Philippe).
Document 7: Flag of Belgium: The national flag of the kingdom of Belgium (Dutch: Vlag van het koninkrijk België, French: Drapeau de la Belgique, German: Flagge Belgiens) is a tricolour of three bands of black, yellow, and red. The colours were taken from the coat of arms of the Duchy of Brabant, and the vertical design may be based on the flag of France. When flown, the black band is nearest the pole (at the hoist side). It has the unusual proportions of 13: 15.
Document 8: Athletics at the 1920 Summer Olympics: At the 1920 Summer Olympics held in Antwerp, 29 athletics events were contested, all for men only. The competitions were held from August 15, 1920 to August 23, 1920.
Document 9: Panama Canal Zone: The Spanish -- American War of 1898 added new life to the canal debate. During the war, American warships in the Atlantic seeking to reach battle zones in the Pacific had been forced to round Cape Horn. Influential naval pundits, such as Captain Alfred Thayer Mahan, urged the construction of a Central American canal. In 1902, with the French efforts moribund, US President Theodore Roosevelt backed the Panama route, and Congress passed legislation authorizing him to purchase the French assets on the condition that an agreement was reached with Colombia. In March 1902, Colombia set its terms for such a treaty: Colombia was to be sovereign over the canal, which would be policed by Colombians paid for by the United States. The host nation would receive a larger percentage of the tolls than provided for in earlier draft treaties. The draft terms were quickly rejected by American officials. Roosevelt was in a hurry to secure the treaty; the Colombians, to whom the French property would revert in 1904, were not. Negotiations dragged on into 1903, during which time there was unrest in Panama City and Colón; the United States sent in Marines to guard the trains. Nevertheless, in early 1903, the United States and Colombia signed a treaty which, despite Colombia's previous objections, gave the United States a 6 miles (9.7 km) wide zone in which it could deploy troops with Colombian consent. On August 12, 1903, the Colombian Senate voted down the treaty 24 -- 0.
Document 10: League of Nations: The World Disarmament Conference was convened by the League of Nations in Geneva in 1932, with representatives from 60 states. A one - year moratorium on the expansion of armaments, later extended by a few months, was proposed at the start of the conference. The Disarmament Commission obtained initial agreement from France, Italy, Spain, Japan, and Britain to limit the size of their navies. The Kellogg -- Briand Pact, facilitated by the commission in 1928, failed in its objective of outlawing war. Ultimately, the Commission failed to halt the military build - up by Germany, Italy, Spain and Japan during the 1930s. The League was mostly silent in the face of major events leading to the Second World War, such as Hitler's remilitarisation of the Rhineland, occupation of the Sudetenland and Anschluss of Austria, which had been forbidden by the Treaty of Versailles. In fact, League members themselves re-armed. In 1933, Japan simply withdrew from the League rather than submit to its judgement, as did Germany the same year (using the failure of the World Disarmament Conference to agree to arms parity between France and Germany as a pretext), Italy and Spain in 1937. The final significant act of the League was to expel the Soviet Union in December 1939 after it invaded Finland.
Document 11: Switzerland: A large number of international institutions have their seats in Switzerland, in part because of its policy of neutrality. Geneva is the birthplace of the Red Cross and Red Crescent Movement and the Geneva Conventions and, since 2006, hosts the United Nations Human Rights Council. Even though Switzerland is one of the most recent countries to have joined the United Nations, the Palace of Nations in Geneva is the second biggest centre for the United Nations after New York, and Switzerland was a founding member and home to the League of Nations.
Document 12: League of Nations: There were several border conflicts between Colombia and Peru in the early part of the 20th century, and in 1922, their governments signed the Salomón-Lozano Treaty in an attempt to resolve them. As part of this treaty, the border town of Leticia and its surrounding area was ceded from Peru to Colombia, giving Colombia access to the Amazon River. On 1 September 1932, business leaders from Peruvian rubber and sugar industries who had lost land, as a result, organised an armed takeover of Leticia. At first, the Peruvian government did not recognise the military takeover, but President of Peru Luis Sánchez Cerro decided to resist a Colombian re-occupation. The Peruvian Army occupied Leticia, leading to an armed conflict between the two nations. After months of diplomatic negotiations, the governments accepted mediation by the League of Nations, and their representatives presented their cases before the Council. A provisional peace agreement, signed by both parties in May 1933, provided for the League to assume control of the disputed territory while bilateral negotiations proceeded. In May 1934, a final peace agreement was signed, resulting in the return of Leticia to Colombia, a formal apology from Peru for the 1932 invasion, demilitarisation of the area around Leticia, free navigation on the Amazon and Putumayo Rivers, and a pledge of non-aggression.

Document 14: Switzerland: The establishment of the Swiss Confederation is traditionally dated to 1 August 1291, which is celebrated annually as the Swiss National Day. The country has a long history of armed neutrality—it has not been in a state of war internationally since 1815—and did not join the United Nations until 2002. Nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to numerous international organizations, including the second largest UN office. On the European level, it is a founding member of the European Free Trade Association, but notably it is not part of the European Union, nor the European Economic Area. However the country does participate in the Schengen Area and the EU's single market through a number of bilateral treaties.
Document 15: Switzerland: Apart from the United Nations headquarters, the Swiss Confederation is host to many UN agencies, like the World Health Organization (WHO), the International Labour Organization (ILO), the International Telecommunication Union (ITU), the United Nations High Commissioner for Refugees (UNHCR) and about 200 other international organisations, including the World Trade Organization and the World Intellectual Property Organization. The annual meetings of the World Economic Forum in Davos bring together top international business and political leaders from Switzerland and foreign countries to discuss important issues facing the world, including health and the environment. Additionally the headquarters of the Bank for International Settlements (BIS) are located in Basel since 1930.
