Central Powers in the context of "Treaty of London (1915)"

The history of Egypt under the British lasted from 1882, when it was occupied by British forces during the Anglo-Egyptian War, until 18 June 1956, when the last British forces withdrew in accordance with the Anglo-Egyptian evacuation agreement of 1954. The first period of British rule (1882–1914) is often called the "veiled protectorate". During this time the Khedivate of Egypt remained an autonomous province of the Ottoman Empire, and the British occupation had no legal basis but constituted a de facto protectorate over the country. Egypt was thus not part of the British Empire. This state of affairs lasted until 1914 when the Ottoman Empire joined World War I on the side of the Central Powers and Britain declared a protectorate over Egypt. The ruling khedive, Abbas II, was deposed and his successor, Hussein Kamel, compelled to declare himself Sultan of Egypt independent of the Ottomans in December 1914.

The formal protectorate over Egypt outlasted the war for only a short period. It was brought to an end when the British government issued the Unilateral Declaration of Egyptian Independence on 28 February 1922. Shortly afterwards, Sultan Fuad I declared himself King of Egypt, but the British occupation continued, in accordance with several reserve clauses in the declaration of independence. The situation was normalised in the Anglo-Egyptian treaty of 1936, which granted Britain the right to station troops in Egypt for the defence of the Suez Canal, its link with India. Britain also continued to control the training of the Egyptian Army. During World War II (1939–1945), Egypt came under attack from Italian Libya on account of the British presence there, although Egypt itself remained neutral until late in the war.

World War I, or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers. Major areas of conflict included Europe and the Middle East, as well as parts of Africa and the Asia-Pacific. The war saw important developments in weaponry including tanks, aircraft, artillery, machine guns, and chemical weapons. One of the deadliest conflicts in history, it resulted in an estimated 30 million military casualties, and 8 million civilian deaths from war-related causes and genocide. The movement of large numbers of people was a major factor in the deadly Spanish flu pandemic.

The causes of World War I included the rise of the German Empire and decline of the Ottoman Empire, which disturbed the long-standing balance of power in Europe, the exacerbation of imperial rivalries, and an arms race between the great powers. Growing tensions in the Balkans reached a breaking point on 28 June 1914 when Gavrilo Princip, a Bosnian Serb, assassinated Franz Ferdinand, the heir to the Austro-Hungarian throne. Austria-Hungary blamed Serbia, and declared war on 28 July. After Russia mobilised in Serbia's defence, Germany declared war on Russia and France, who had an alliance. The United Kingdom entered the war after Germany invaded Belgium, and the Ottoman Empire joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France before transferring its forces to the east, but its advance was halted in September, and by the end of the year the Western Front consisted of a near-continuous line of trenches from the English Channel to Switzerland. The Eastern Front was more dynamic, but neither side gained a decisive advantage, despite costly offensives. Italy, Bulgaria, Romania, Greece and others entered the war from 1915 onward.

The sultans of the Ottoman Empire (Turkish: Osmanlı padişahları), who were all members of the Ottoman dynasty (House of Osman), ruled over the transcontinental empire from its perceived inception in 1299 to its dissolution in 1922. At its height, the Ottoman Empire spanned an area from Hungary in the north to Yemen in the south and from Algeria in the west to Iraq in the east. Administered at first from the city of Söğüt since before 1280 and then from the city of Bursa since 1323 or 1324, the empire's capital was moved to Adrianople (now known as Edirne in English) in 1363 following its conquest by Murad I and then to Constantinople (present-day Istanbul) in 1453 following its conquest by Mehmed II.

The Ottoman Empire's early years have been the subject of varying narratives, due to the difficulty of discerning fact from legend. The empire came into existence at the end of the 13th century, and its first ruler (and the namesake of the Empire) was Osman I. According to later, often unreliable Ottoman tradition, Osman was a descendant of the Kayı tribe of the Oghuz Turks. The eponymous Ottoman dynasty he founded endured for six centuries through the reigns of 36 sultans. The Ottoman Empire disappeared as a result of the defeat of the Central Powers, with whom it had allied itself during World War I. The partitioning of the Empire by the victorious Allies and the ensuing Turkish War of Independence led to the abolition of the sultanate in 1922 and the birth of the modern Republic of Turkey in 1922.

The Russian Civil War (Russian: Гражданская война в России, romanized: Grazhdanskaya voyna v Rossii) was a multi-party civil war in the former Russian Empire sparked by the 1917 overthrowing of the Russian Provisional Government in the October Revolution, as many factions vied to determine Russia's political future. It resulted in the formation of the Russian Socialist Federative Soviet Republic and later the Soviet Union in most of its territory. Its finale marked the end of the Russian Revolution, which was one of the key events of the 20th century.

The Russian monarchy ended with the abdication of Tsar Nicholas II during the February Revolution, and Russia was in a state of political flux. A tense summer culminated in the October Revolution, where the Bolsheviks overthrew the provisional government of the new Russian Republic. Bolshevik seizure of power was not universally accepted, and the country descended into a conflict which became a full-scale civil war in May–June 1918. The two largest combatants were the Red Army, fighting for the establishment of a Bolshevik-led socialist state headed by Vladimir Lenin, and the forces known as the White movement (and its White Army), led mainly by the right-leaning officers of the Russian Empire, united around the figure of Alexander Kolchak. In addition, rival militant socialists, notably the Ukrainian anarchists of the Makhnovshchina and Left Socialist-Revolutionaries, were involved in conflict against the Bolsheviks. They, as well as non-ideological green armies, opposed the Bolsheviks, the Whites and the foreign interventionists. Thirteen foreign states intervened against the Red Army, notably the Allied intervention, whose primary goal was re-establishing the Eastern Front of World War I. Three foreign states of the Central Powers also intervened, rivaling the Allied intervention with the main goal of retaining the territory they had received in the Treaty of Brest-Litovsk with Soviet Russia.

The Fourteen Points was a statement of principles for peace that was to be used for peace negotiations in order to end World War I. The principles were outlined in a January 8, 1918 speech on war aims and peace terms to the United States Congress by President Woodrow Wilson. However, his main Allied colleagues (Georges Clemenceau of France, David Lloyd George of the United Kingdom, and Vittorio Emanuele Orlando of Italy) were skeptical of the applicability of Wilsonian idealism.

The United States had joined the Triple Entente in fighting the Central Powers on April 6, 1917. Its entry into the war had in part been due to Germany's resumption of submarine warfare against merchant ships trading with France and Britain and also the interception of the Zimmermann telegram. However, Wilson wanted to avoid the United States' involvement in the long-standing European tensions between the great powers; if America was going to fight, he wanted to try to separate that participation in the war from nationalistic disputes or ambitions. The need for moral aims was made more important when, after the fall of the Russian government, the Bolsheviks disclosed secret treaties made between the Allies. Wilson's speech also responded to Vladimir Lenin's Decree on Peace of November 1917, immediately after the October Revolution in 1917.

Abbas Helmy II (also known as ʿAbbās Ḥilmī Pāshā, Arabic: عباس حلمي باشا; 14 July 1874 – 19 December 1944) was the last Khedive of Egypt and the Sudan, ruling from 8 January 1892 to 19 December 1914. In 1914, after the Ottoman Empire joined the Central Powers in World War I, the nationalist Khedive was removed by the British, then ruling Egypt, in favour of his more pro-British uncle, Hussein Kamel, marking the de jure end of Egypt's four-century era as a province of the Ottoman Empire, which had begun in 1517.

Nestor Ivanovych Makhno (Ukrainian: Нестор Іванович Махно, pronounced [ˈnɛstor iˈwɑnowɪtʃ mɐxˈnɔ]; 7 November 1888 – 25 July 1934), also known as Bat'ko Makhno (Ukrainian: Бáтько Махно́ [ˈbɑtʲko mɐxˈnɔ], lit. 'Father Makhno'), was a Ukrainian anarchist revolutionary and the commander of the Revolutionary Insurgent Army of Ukraine during the Ukrainian War of Independence. He established the Makhnovshchina (loosely translated as "Makhno movement"), a mass movement by the Ukrainian peasantry to establish anarchist communism in the country between 1918 and 1921. Initially centered around Makhno's home province of Katerynoslav and hometown of Huliaipole, it came to exert a strong influence over large areas of southern Ukraine, specifically in what is now the Zaporizhzhia Oblast of Ukraine.

Raised by a peasant family and coming of age amid the fervor around the 1905 Revolution, Makhno participated in a local anarchist group and spent seven years imprisoned for his involvement. With his release during the 1917 Revolution, Makhno became a local revolutionary leader in his hometown and oversaw the expropriation and redistribution of large estates to the peasantry. In the Ukrainian Civil War, Makhno sided with the Soviet Russian Bolsheviks against the Ukrainian nationalists and White movement, but his alliances with the Bolsheviks did not last. He rallied Bolshevik support to lead an insurgency, defeating the Central Powers' occupation forces at the Battle of Dibrivka and establishing the Makhnovshchina. Makhno's troops briefly integrated with the Bolshevik Red Army in the 1919 Soviet invasion of Ukraine, but split over differences on the movement's autonomy. Makhno rebuilt his army from the remains of Nykyfor Hryhoriv's forces in western Ukraine, routed the White Army at the Battle of Perehonivka, and captured most of southern and eastern Ukraine, where they again attempted to establish anarchist communism.
