Beginning from the late eighteenth century, the Ottoman Empire faced challenges defending itself against foreign invasion and occupation.
 In response to foreign threats, the empire initiated a period of tremendous internal reform which came to be known as the Tanzimat, which succeeded in significantly strengthening the Ottoman central state, despite the empire's precarious international position.
 Over the course of the nineteenth century, the Ottoman state became increasingly powerful and rationalized, exercising a greater degree of influence over its population than in any previous era.
 The process of reform and modernization in the empire began with the declaration of the Nizam-ı Cedid (New Order) during the reign of Sultan Selim III (r. 1789-1807) and was punctuated by several reform decrees, such as the Hatt-ı Şerif of Gülhane in 1839 and the Hatt-ı Hümayun in 1856.
 At the end of this period, marked with 1908, to a degree the Ottoman military became modernized and professionalized according to the model of Western European Armies.
 The period was followed by defeat and dissolution of the Ottoman Empire (1908–1922).
The Lala Mustafa Pasha Mosque (Turkish: Lala Mustafa Paşa Camii), originally known as the Cathedral of Saint Nicholas and later as the Ayasofya (Saint Sophia) Mosque of Mağusa, is the largest medieval building in Famagusta, Northern Cyprus.
 Built between 1298 and c. 1400, it was consecrated as a Roman Catholic cathedral in 1328.
 The cathedral was converted into a mosque after the Ottoman Empire captured Famagusta in 1571 and it remains a mosque to this day.
 From 1954 the building has taken its name from Lala Mustafa Pasha, the Grand Vizier of the Ottoman Empire from Sokolovići in Bosnia, who served Murat III and led Ottoman forces against the Venetians in Cyprus.

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.
Dolmabahçe Clock Tower (Turkish: "Dolmabahçe Saat Kulesi" ) is a clock tower situated outside Dolmabahçe Palace in Istanbul, Turkey.

Abdülmecid I (Ottoman Turkish: عبد المجيد اول "‘Abdü’l-Mecīd-i evvel"; 23/25 April 182325 June 1861), also known as Abdulmejid and similar spellings, was the 31st Sultan of the Ottoman Empire and succeeded his father Mahmud II on 2 July 1839.
 His reign was notable for the rise of nationalist movements within the empire's territories.
 Abdulmejid wanted to encourage Ottomanism among the secessionist subject nations and stop the rise of nationalist movements within the empire, but failed to succeed despite trying to integrate non-Muslims and non-Turks more thoroughly into Ottoman society with new laws and reforms.
 He tried to forge alliances with the major powers of Western Europe, namely the United Kingdom and France, who fought alongside the Ottoman Empire in the Crimean War against Russia.
 In the following Congress of Paris on 30 March 1856, the Ottoman Empire was officially included among the European family of nations.
 Abdulmejid's biggest achievement was the announcement and application of the Tanzimat "(reorganization)" reforms which were prepared by his father and effectively started the modernization of the Ottoman Empire in 1839.
 For this achievement, one of the Imperial anthems of the Ottoman Empire, the March of Abdulmejid, was named after him.
