Document 2: Separate peace: The phrase "separate peace" refers to a nation's agreement to cease military hostilities with another, even though the former country had previously entered into a military alliance with other states that remain at war with the latter country. For example, at the start of World War I (1914–1918), Russia was a member, with the United Kingdom and France, of the Triple Entente, which went to war with the Central Powers formed by Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. After the fall of Russian monarch Nicholas II and the rise to power of the Bolsheviks, Russia defaulted on its commitments to the Triple Entente by signing a separate peace with Germany and its allies in 1917. This armistice was followed on 3 March 1918 by the formal signing of the Treaty of Brest-Litovsk.
Document 3: List of last World War I veterans by country: This is a list of the last World War I veterans to die by country.

Document 5: Burgfriedenspolitik: Burgfriedenspolitik (] )—literally "castle peace politics" but more accurately a political policy of "party truce" — is a German term used for the political truce the Social Democratic Party of Germany and the other political parties agreed to during World War I. The trade unions refrained from striking, the SPD voted for war credits in the Reichstag and the parties agreed not to criticize the government and its war. There were several reasons for the "Burgfrieden" politics: the Social Democrats believed it was their patriotic duty to support the government in war; they were afraid of government repression should they protest against the war; they feared living under an autocratic Russian Czar more than the German constitutional monarchy and its Kaiser; and they hoped to achieve political reforms after the war, including the abrogation of the inequitable three-class voting system, by cooperating with the government.

Document 13: Armistice of 11 November 1918: The Armistice of 11 November 1918 was an armistice during the First World War between the Allies and Germany – also known as the Armistice of Compiègne after the location in which it was signed – and the agreement that ended the fighting on the Western Front. It went into effect at 11 a.m. Paris time on 11 November 1918 ("the eleventh hour of the eleventh day of the eleventh month"), and marked a victory for the Allies and a complete defeat for Germany, although not formally a surrender. The Germans were responding to the policies proposed by U.S. President Woodrow Wilson in his Fourteen Points of January 1918. The actual terms, largely written by French Marshal and Supreme Commander of the Allied Armies Ferdinand Foch, included the cessation of hostilities, the withdrawal of German troops to behind their own borders, the preservation of infrastructure, the exchange of prisoners, a promise of reparations, the disposition of German warships and submarines, and conditions for prolonging or terminating the armistice. Although the armistice ended the actual fighting, it took six months of negotiations at the Paris Peace Conference to conclude the peace treaty, the Treaty of Versailles.

A two-minute silence is also observed on Remembrance Sunday, also at 11.00am.
