Question: Anzac day was created because of a war that took place where?

full_context: Document 1: Anzac Day: Anzac Day is a national day of remembrance in Australia and New Zealand that broadly commemorates all Australians and New Zealanders "who served and died in all wars, conflicts, and peacekeeping operations" and "the contribution and suffering of all those who have served". Observed on 25 April each year, Anzac Day was originally to honour the members of the Australian and New Zealand Army Corps (ANZAC) who fought at Gallipoli against the Ottoman Empire during World War I.
Document 2: Siege of Sevastopol (1941–42): The Siege of Sevastopol also known as the Defence of Sevastopol (Russian: Оборона Севастополя , transliteration: "Oborona Sevastopolya") or simply the Battle of Sevastopol (German: Schlacht um Sewastopol) was a military battle and a siege that took place on the Eastern Front of the Second World War. The campaign was fought by the Axis powers of Germany, Romania, and Italy against the Soviet Union for control of Sevastopol, a port in the Crimea on the Black Sea. On 22 June 1941 the Axis invaded the Soviet Union during Operation Barbarossa. Axis land forces reached the Crimea in the autumn of 1941 and overran most of the area. The only objective not in Axis hands was Sevastopol. Several attempts were made to secure the city in October and November 1941. A major attack was planned for late November, but heavy rains delayed the Axis attack until 17 December 1941. Under the command of Erich von Manstein, Axis forces were unable to capture Sevastopol during this first operation. Soviet forces launched an amphibious landing on the Crimean peninsula at Kerch in December 1941 to relieve the siege and force the Axis to divert forces to defend their gains. The operation saved Sevastopol for the time being, but the bridgehead in the eastern Crimea was eliminated in May 1942.
Document 3: Greek Summer Offensive (1920): The Greek Summer Offensive of 1920 was an offensive by the Greek army, assisted by British forces, to capture the southern region of the Sea of Marmara and the Aegean Region from the Kuva-yi Milliye (National Forces) of the provisional Turkish national movement government in Ankara. Additionally, the Greek and British forces were supported by the Kuva-yi Inzibatiye (Forces of Order) of the Ottoman government in Constantinople, which sought to crush the Turkish nationalist forces. The offensive was part of the Greco-Turkish War and was one of several engagements where British troops assisted the advancing Greek army. British troops actively took part in invading coastal towns of the Sea of Marmara. With the approval of the Allies, the Greeks started their offensive on 22 June 1920 and crossed the 'Milne Line'. The 'Milne Line' was the demarcation line between Greece and Turkey, laid down in Paris. Resistance by the Turks was limited, as they had few and ill-equipped troops in western Anatolia. They were also busy on the eastern and southern fronts. After offering some opposition, they retreated to Eskişehir on Mustafa Kemal Pasha's order.
Document 4: National War Memorial (South Australia): The National War Memorial is a monument on the north edge of the city centre of Adelaide, South Australia, commemorating those who served in the First World War. Opened in 1931, the memorial is located on the corner of North Terrace and Kintore Avenue, adjacent to the grounds of Government House. Memorial services are held at the site throughout the year, with major services on both Anzac Day (25 April) and Remembrance Day (11 November).
Document 5: Partition of the Ottoman Empire: The partition of the Ottoman Empire (Armistice of Mudros, 30 October 1918 – Abolition of the Ottoman Sultanate, 1 November 1922) was a political event that occurred after World War I and the occupation of Constantinople by British, French and Italian troops in November 1918. The partitioning was planned in several agreements made by the Allies early in the course of World War I, notably the Sykes-Picot Agreement. As world war loomed, the Ottoman Empire sought protection but was rejected by Britain, France, and Russia, and finally formed the Ottoman–German Alliance. The huge conglomeration of territories and peoples that formerly comprised the Ottoman Empire was divided into several new states. The Ottoman Empire had been the leading Islamic state in geopolitical, cultural and ideological terms. The partitioning of the Ottoman Empire led to the rise in the Middle East of Western powers such as Britain and France and brought the creation of the modern Arab world and the Republic of Turkey. Resistance to the influence of these powers came from the Turkish national movement but did not become widespread in the post-Ottoman states until after World War II.
Document 6: Gallipoli Campaign: The Gallipoli Campaign, also known as the Dardanelles Campaign, the Battle of Gallipoli, or the Battle of Çanakkale (Turkish: "Çanakkale Savaşı" ), was a campaign of the First World War that took place on the Gallipoli peninsula (Gelibolu in modern Turkey) in the Ottoman Empire between 25 April 1915 and 9 January 1916. The peninsula forms the northern bank of the Dardanelles, a strait that provided a sea route to the Russian Empire, one of the Allied powers during the war. Intending to secure it, Russia's allies, Britain and France, launched a naval attack followed by an amphibious landing on the peninsula, with the aim of capturing the Ottoman capital of Constantinople (modern Istanbul). The naval attack was repelled and after eight months' fighting, with many casualties on both sides, the land campaign was abandoned and the invasion force was withdrawn to Egypt.
Document 7: ANZAC (acronym): The ANZAC acronym came from the Australian and New Zealand Army Corps, formed in Egypt prior to the Gallipoli Campaign during the First World War. The corps was the higher formation for all Australian and New Zealand soldiers. It then gave its name to ANZAC Cove, on the Gallipoli peninsula, and at first was only used to identify the men who took part in the Gallipoli landings, although it later came to mean "any Australian or New Zealand soldier of the First World War." Both the 'ANZAC' and the 'Anzac' versions of the acronym have been protected by the Commonwealth Government of Australia.
Document 8: Australian and New Zealand Army Corps: The Australian and New Zealand Army Corps (ANZAC) was a First World War army corps of the Mediterranean Expeditionary Force. It was formed in Egypt in December 1914, and operated during the Battle of Gallipoli. General William Birdwood commanded the corps, which comprised troops from the First Australian Imperial Force and 1st New Zealand Expeditionary Force. The corps disbanded in 1916, following the Allied evacuation of the Gallipoli peninsula and the formation of I ANZAC Corps and II ANZAC Corps. The Corps was reestablished, briefly, in the Second World War during the Battle of Greece in 1941.
Document 9: Battle of Chunuk Bair: The Battle of Chunuk Bair (Turkish: Conk Bayırı Muharebesi ) was a World War I battle fought between the Ottoman defenders and troops of the British Empire. British units that reached the summit of Chunuk Bair early on 8 August 1915 to engage the Turks were the Wellington Battalion of the New Zealand and Australian Division, 7th Battalion, Gloucestershire Regiment and 8th Battalion, Welch Regiment of the 13th (Western) Division. The troops were reinforced in the afternoon by two squads of the Auckland Mounted Rifles Regiment, New Zealand and Australian Division. The first troops on summit were severely depleted by Ottoman return fire and were relieved at 10:30 pm on 8 August by the Otago Battalion (NZ), and the Wellington Mounted Rifles Regiment New Zealand and Australian Division. The New Zealand troops were relieved by 8:00 pm on 9 August by the 6th Battalion, Loyal North Lancashire Regiment and 5th Battalion, Wiltshire Regiment, who were massacred and driven off the summit in the early morning of 10 August, by an Ottoman counter-attack led by Mustafa Kemal. The capture of Chunuk Bair, (Turkish: "Çanak Bayır" Basin Slope, now "Conk Bayırı"), the secondary peak of the Sari Bair range, was one of the two objectives of the Battle of Sari Bair, the British August Offensive at Anzac Cove and Suvla, to try to break the stalemate that the campaign had become. The capture of Chunuk Bair was the only success for the Allies of the campaign but it was fleeting as the position proved untenable. The Ottomans recaptured the peak for good a few days later.
Document 10: First Battle of the Marne: The Battle of the Marne (French: Première bataille de la Marne , also known as the Miracle of the Marne, "Le Miracle de la Marne") was a World War I battle fought from 6–10 September 1914. It resulted in an Allied victory against the German armies in the west. The battle was the culmination of the German advance into France and pursuit of the Allied armies which followed the Battle of the Frontiers in August and had reached the eastern outskirts of Paris. A counter-attack by six French armies and the British Expeditionary Force (BEF) along the Marne River forced the Imperial German Army to retreat north-west, leading to the First Battle of the Aisne and the Race to the Sea. The battle was a victory for the Allies but led to four years of trench warfare stalemate on the Western Front.
Document 11: Macedonian Front: The Macedonian Front of World War I, also known as the Salonica Front (after Thessaloniki), was formed as a result of an attempt by the Allied Powers to aid Serbia, in the fall of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and in insufficient force to prevent the fall of Serbia, and was complicated by the internal political crisis in Greece (the "National Schism"). Eventually, a stable front was established, running from the Albanian Adriatic coast to the Struma River, pitting a multinational Allied force against the Bulgarian Army, which was at various times bolstered with smaller units from the other Central Powers. The Macedonian Front remained quite stable, despite local actions, until the great Allied offensive in September 1918, which resulted in the capitulation of Bulgaria and the liberation of Serbia.
Document 12: Galata: Galata (in Greek was known as Galatás, Γαλατᾶς) was a neighbourhood opposite Constantinople (today's Istanbul, Turkey), located at the northern shore of the Golden Horn, the inlet which separates it from the historic peninsula of old Constantinople. The Golden Horn is crossed by several bridges, most notably the Galata Bridge. The medieval citadel of Galata was a colony of the Republic of Genoa between 1273 and 1453. The famous Galata Tower was built by the Genoese in 1348 at the northernmost and highest point of the citadel. At present, Galata is a quarter within the borough of Beyoğlu (Pera) in Istanbul, and is known as Karaköy.
Document 13: Shrine of Remembrance: The Shrine of Remembrance, located in Kings Domain on St Kilda Road, Melbourne, Australia was built as a memorial to the men and women of Victoria who served in World War I and is now a memorial to all Australians who have served in war. It is a site of annual observances of ANZAC Day (25 April) and Remembrance Day (11 November) and is one of the largest war memorials in Australia.
Document 14: Two-minute silence: In the United Kingdom and other countries within the Commonwealth, a two-minute silence is observed as part of Armistice Day to remember those who lost their lives in conflict. Held each year at 11.00am on 11 November, the silence coincides with the time in 1918 at which the First World War came to an end with the cessation of hostilities, and is generally observed at war memorials and in public places throughout the UK and Commonwealth. A two-minute silence is also observed on Remembrance Sunday, also at 11.00am.
Document 15: Remembrance Day: Remembrance Day (sometimes known informally as Poppy Day) is a memorial day observed in Commonwealth of Nations member states since the end of the First World War to remember the members of their armed forces who have died in the line of duty. Following a tradition inaugurated by King George V in 1919, the day is also marked by war remembrances in many non-Commonwealth countries. Remembrance Day is observed on 11 November in most countries to recall the end of hostilities of World War I on that date in 1918. Hostilities formally ended "at the 11th hour of the 11th day of the 11th month", in accordance with the armistice signed by representatives of Germany and the Entente between 5:12 and 5:20 that morning. ("At the 11th hour" refers to the "passing" of the 11th hour, or 11:00 am.) The First World War officially ended with the signing of the Treaty of Versailles on 28 June 1919.
