The Erzurum offensive or Battle of Erzurum was a major winter offensive by the Imperial Russian Army on the Caucasus Campaign, during the First World War that led to the capture of the strategic city of Erzurum. The Ottoman forces, in winter quarters, suffered a series of unexpected reverses, which led to a Russian victory.
The Caucasus campaign comprised armed conflicts between the Russian Empire and the Ottoman Empire, later including Armenia, Azerbaijan, Georgia, the Mountainous Republic of the Northern Caucasus, the German Empire, the Central Caspian Dictatorship, and the British Empire, as part of the Middle Eastern theatre during World War I. The Caucasus campaign extended from the South Caucasus to the Armenian Highlands region, reaching as far as Trabzon, Bitlis, Mush and Van. The land warfare was accompanied by naval engagements in the Black Sea.
The African theatre of the First World War comprises campaigns in North Africa instigated by the German and Ottoman empires, local rebellions against European colonial rule and Allied campaigns against the German colonies of Kamerun, Togoland, German South West Africa, and German East Africa. The campaigns were fought by German Schutztruppe, local resistance movements and forces of the British Empire, France, Italy, Belgium, and Portugal.

The Third Army was originally established in Skopje and later defended the northeastern provinces of the Ottoman Empire. Its initial headquarters was at Salonica, where it formed the core of the military forces that supported the Young Turk Revolution of 1908. Many of its officers who participated in the Revolution, including Enver Pasha and Mustafa Kemal Atatürk, rose to fame and power.
The Senussi campaign took place in North Africa from November 1915 to February 1917, during the First World War. The campaign was fought by the Kingdom of Italy and the British Empire against the Senussi, a religious order of Arabic nomads in Libya and Egypt. The Senussi were courted by the Ottoman Empire and the German Empire. Recognising French and Italian threats, the Ottoman Sultan Abdulhamid II had twice sent his aide-de-camp Azmzade Sadik El Mueyyed to meet Sheikh Muhammed El Mehdi El Senussi to cultivate positive relations and counter the west European scramble for Africa. In the summer of 1915, the Ottomans persuaded the Grand Senussi Ahmed Sharif as-Senussi to declare jihad, attack British-occupied Egypt from the west and to encourage insurrection in Egypt to divert British forces.
Conflicts took place in North Africa during World War I (1914–1918) between the Central Powers and the Entente and its allies. The Senussi of Libya sided with the Ottoman Empire and the German Empire against the British Empire and the Kingdom of Italy. On 14 November 1914, the Ottoman Sultan proclaimed a jihad and sought to create a diversion to draw British troops from the Sinai and Palestine Campaign. Italy wished to preserve its gains from the Italo-Turkish War. The Senussi Campaign took place in North Africa from 23 November 1915 to February 1917.
