Document 3: Ottoman Empire: The Serbian revolution (1804–1815) marked the beginning of an era of national awakening in the Balkans during the Eastern Question. Suzerainty of Serbia as a hereditary monarchy under its own dynasty was acknowledged de jure in 1830. In 1821, the Greeks declared war on the Sultan. A rebellion that originated in Moldavia as a diversion was followed by the main revolution in the Peloponnese, which, along with the northern part of the Gulf of Corinth, became the first parts of the Ottoman Empire to achieve independence (in 1829). By the mid-19th century, the Ottoman Empire was called the "sick man" by Europeans. The suzerain states – the Principality of Serbia, Wallachia, Moldavia and Montenegro – moved towards de jure independence during the 1860s and 1870s.

British and allied forces had conquered Baghdad, Damascus, and Jerusalem during the war and most of the Ottoman Empire was divided amongst the European allies. At the San Remo conference of April 1920, the French were granted a mandate over Syria and the British were granted one over Palestine and Mesopotamia. On 10 August 1920, Mehmed's representatives signed the Treaty of Sèvres, which recognised the mandates and recognised Hejaz as an independent state.

Document 7: Middle Ages: Although the Palaeologi emperors recaptured Constantinople from the Western Europeans in 1261, they were never able to regain control of much of the former imperial lands. They usually controlled only a small section of the Balkan Peninsula near Constantinople, the city itself, and some coastal lands on the Black Sea and around the Aegean Sea. The former Byzantine lands in the Balkans were divided between the new Kingdom of Serbia, the Second Bulgarian Empire and the city-state of Venice. The power of the Byzantine emperors was threatened by a new Turkish tribe, the Ottomans, who established themselves in Anatolia in the 13th century and steadily expanded throughout the 14th century. The Ottomans expanded into Europe, reducing Bulgaria to a vassal state by 1366 and taking over Serbia after its defeat at the Battle of Kosovo in 1389. Western Europeans rallied to the plight of the Christians in the Balkans and declared a new crusade in 1396; a great army was sent to the Balkans, where it was defeated at the Battle of Nicopolis. Constantinople was finally captured by the Ottomans in 1453.

Document 9: Ottoman Bulgaria: The history of Ottoman Bulgaria spans nearly 500 years, from the conquest by the Ottoman Empire of the smaller kingdoms emerging from the disintegrating Second Bulgarian Empire in the late 14th century, to the Liberation of Bulgaria in 1878. As a result of the Russo-Turkish War (1877–1878), the Principality of Bulgaria, a self-governing Ottoman vassal state that was functionally independent, was created. In 1885 the autonomous province of Eastern Rumelia came under the control of the Bulgarian Tsar. Bulgaria declared independence in 1908.
Document 10: Sinai and Palestine campaign: After a period of stalemate in Southern Palestine from April to October 1917, General Edmund Allenby captured Beersheba from the III Corps. Having weakened the Ottoman defences, which had stretched almost continually from Gaza to Beersheba, they were finally captured by 8 November, after the Battle of Tel el Khuweilfe, the Battle of Hareira and Sheria and the Third Battle of Gaza, when the pursuit began. During the subsequent operations, about of formerly Ottoman territory was captured as a result of the EEF victories at the Battle of Mughar Ridge, fought between 10 and 14 November, and the Battle of Jerusalem, fought between 17 November and 30 December. Serious losses on the Western Front in March 1918, during Erich Ludendorff's German Spring Offensive, forced the British Empire to send reinforcements from the EEF. During this time, two unsuccessful attacks were made to capture Amman and to capture Es Salt in March and April 1918, before Allenby's force resumed the offensive during the manoeuvre warfare of the Battle of Megiddo. The successful infantry battles at Tulkarm and Tabsor created gaps in the Ottoman front line, allowing the pursuing Desert Mounted Corps to encircle the infantry fighting in the Judean Hills and fight the Battle of Nazareth and Battle of Samakh, capturing Afulah, Beisan, Jenin and Tiberias. In the process the EEF destroyed three Ottoman armies during the Battle of Sharon, the Battle of Nablus and the Third Transjordan attack, capturing thousands of prisoners and large quantities of equipment. Damascus and Aleppo were captured during the subsequent pursuit, before the Ottoman Empire agreed to the Armistice of Mudros on 30 October 1918, ending the Sinai and Palestine campaign. The British Mandate of Palestine and the French Mandate for Syria and Lebanon were created to administer the captured territories.

Document 12: History of Palestine: The British - led Egyptian Expeditionary Force, commanded by Edmund Allenby, captured Jerusalem on 9 December 1917 and occupied the whole of the Levant following the defeat of Turkish forces in Palestine at the Battle of Megiddo in September 1918 and the capitulation of Turkey on 31 October.

Document 13: Ottoman Empire: The Ottoman bashi-bazouks brutally suppressed the Bulgarian uprising of 1876, massacring up to 100,000 people in the process. The Russo-Turkish War (1877–78) ended with a decisive victory for Russia. As a result, Ottoman holdings in Europe declined sharply; Bulgaria was established as an independent principality inside the Ottoman Empire, Romania achieved full independence. Serbia and Montenegro finally gained complete independence, but with smaller territories. In 1878, Austria-Hungary unilaterally occupied the Ottoman provinces of Bosnia-Herzegovina and Novi Pazar.
Document 14: Decline and modernization of the Ottoman Empire: The Russo - Turkish War of 1877 -- 1878 had its origins in a rise in nationalism in the Balkans as well as in the Russian goal of recovering territorial losses it had suffered during the Crimean War, reestablishing itself in the Black Sea and following the political movement attempting to free Balkan nations from the Ottoman Empire. As a result of the war, the principalities of Romania, Serbia and Montenegro, each of which had de facto sovereignty for some time, formally proclaimed independence from the Ottoman Empire. After almost half a millennium of Ottoman domination (1396 -- 1878), the Bulgarian state was reestablished as the Principality of Bulgaria, covering the land between the Danube River and the Balkan Mountains (except Northern Dobrudja which was given to Romania) and the region of Sofia, which became the new state's capital. The Congress of Berlin also allowed Austria - Hungary to occupy Bosnia and Herzegovina and Great Britain to take over Cyprus, while the Russian Empire annexed Southern Bessarabia and the Kars region.
