World War I: First Battle of Gaza: British troops are halted after 17,000 Turks block their advance.

World War I or the First World War, also known as the Great War, was a global conflict between two coalitions: the Allies and the Central Powers. Main areas of conflict included Europe and the Middle East, as well as parts of Africa and the Asia-Pacific. There were 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, plus another 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 First Battle of Gaza was fought on 26 March 1917 during the first attempt by the Egyptian Expeditionary Force (EEF), which was a British Empire military formation, formed on 10 March 1916 under the command of General Archibald Murray from the Mediterranean Expeditionary Force and the Force in Egypt (1914–15), at the beginning of the Sinai and Palestine Campaign of the First World War. Fighting took place in and around the town of Gaza on the Mediterranean coast when infantry and mounted infantry from the Desert Column, a component of the Eastern Force, attacked the town. Late in the afternoon, on the verge of capturing Gaza, the Desert Column was withdrawn due to concerns about the approaching darkness and large Ottoman reinforcements. This British defeat was followed a few weeks later by the even more emphatic defeat of the Eastern Force at the Second Battle of Gaza in April 1917.

Turks, or Turkish people, are the largest Turkic ethnic group, comprising the majority of the population of Turkey and Northern Cyprus. They generally speak the various Turkish dialects. In addition, centuries-old ethnic Turkish communities still exist across other former territories of the Ottoman Empire. Article 66 of the Constitution of Turkey defines a Turk as anyone who is a citizen of the Turkish state. While the legal use of the term Turkish as it pertains to a citizen of Turkey is different from the term's ethnic definition, the majority of the Turkish population are of Turkish ethnicity. The vast majority of Turks are Sunni Muslims, with a notable minority practicing Alevism.
