Ottoman Turkish language in the context of Janissary Corps

Musala (Bulgarian: Мусала [mosɐˈɫa]); from Arabic through Ottoman Turkish: from Musalla, "near God" or "place for prayer" is the highest peak in the Rila Mountains, as well as in Bulgaria and the entire Balkan Peninsula, standing at 2,925.42 metres (9,597.8 ft).

With a topographic prominence of 2,473 metres (8,114 ft), Musala is also the 6th highest peak by topographic prominence in mainland Europe. It is also the 3rd most topographically isolated major peak in Continental Europe.

Rumelia (Ottoman Turkish: روم ايلى, romanized: Rum İli, lit. 'Land of the Romans'; Turkish: Rumeli; Greek: Ρωμυλία) was a historical region in Southeastern Europe that was administered by the Ottoman Empire, roughly corresponding to the Balkans. In its wider sense, it was used to refer to all Ottoman possessions and vassals in Europe. These would later be geopolitically classified as "the Balkans", although Hungary and Moldova are sometimes excluded. In contemporary English sources, Rumelia was known as Turkey in Europe.

Anatolian beyliks (Turkish: Anadolu beylikleri, Ottoman Turkish: Tavâif-i mülûk, Beylik; Turkish pronunciation: [bejlic]) were Turkish principalities (or petty kingdoms) in Anatolia governed by beys, the first of which were founded at the end of the 11th century. A second and more extensive period of establishment took place as a result of the decline of the Seljuq Sultanate of Rûm in the latter half of the 13th century.

One of the beyliks, the ottoman beylik that of the Osmanoğlu of the Kayı branch of Oghuz Turks, from its capital in Bursa completed its incorporation of the other beyliks to form the Ottoman Empire by the late 15th century.

Mehmed II (Ottoman Turkish: محمد ثانى, romanized: Meḥemmed-i s̱ānī; Turkish: II. Mehmed, pronounced [icinˈdʒi ˈmehmet]; 30 March 1432 – 3 May 1481), commonly known as Mehmed the Conqueror (Ottoman Turkish: ابو الفتح, romanized: Ebū'l-fetḥ, lit. 'the Father of Conquest'; Turkish: Fâtih Sultan Mehmed), was twice the sultan of the Ottoman Empire from August 1444 to September 1446 and then later from February 1451 to May 1481.

In Mehmed II's first reign, he defeated the crusade led by John Hunyadi after the Hungarian incursions into his country broke the conditions of the truce per the Treaties of Edirne and Szeged. When Mehmed II ascended the throne again in 1451, he strengthened the Ottoman Navy and made preparations to attack Constantinople. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire. After the conquest, Mehmed claimed the title caesar of Rome (Ottoman Turkish: قیصر روم, romanized: qayṣar-i rūm), based on the fact that Constantinople had been the seat and capital of the surviving Eastern Roman Empire since its consecration in 330 AD by Emperor Constantine I. The claim was soon recognized by the Patriarchate of Constantinople, albeit not by most European monarchs.

Selim I (Ottoman Turkish: سليم الأول; Turkish: I. Selim; 10 October 1470 – 22 September 1520), also known as Selim the Grim or Selim the Resolute (Turkish: Yavuz Sultan Selim), was the sultan of the Ottoman Empire from 1512 to 1520. Despite lasting only eight years, his reign is notable for the enormous expansion of the Empire, particularly his conquest between 1516 and 1517 of the entire Mamluk Sultanate of Egypt, which included all of the Levant, Hejaz, Tihamah and Egypt itself. On the eve of his death in 1520, the Ottoman Empire spanned about 3.4 million km (1.3 million sq mi), having grown by seventy percent during Selim's reign.

Selim's conquest of the Middle Eastern heartlands of the Muslim world, and particularly his assumption of the role of guardian of the pilgrimage routes to Mecca and Medina, established the Ottoman Empire as the pre-eminent Muslim state. His conquests dramatically shifted the empire's geographical and cultural center of gravity away from the Balkans and toward the Middle East. By the eighteenth century, Selim's conquest of the Mamluk Sultanate had come to be romanticized as the moment when the Ottomans seized leadership over the rest of the Muslim world, and consequently Selim is popularly remembered as the first legitimate Ottoman Caliph, although stories of an official transfer of the caliphal office from the Mamluk Abbasid dynasty to the Ottomans were a later invention.

Suleiman I (Ottoman Turkish: سلیمان اول, romanized: Süleymân-ı Evvel; Modern Turkish: I. Süleyman, IPA: [biɾinˈdʒi sylejˈman]; 6 November 1494 – 6 September 1566), commonly known as Suleiman the Magnificent in the Western world and as Suleiman the Lawgiver (قانونی سلطان سلیمان, Ḳânûnî Sulṭân Süleymân) in his own realm, was the Ottoman sultan between 1520 and his death in 1566. Under his administration, the Ottoman Empire ruled over at least 25 million people.

After succeeding his father Selim I on 30 September 1520, Suleiman began his reign by launching military campaigns against the Christian powers of Central and Eastern Europe and the Mediterranean; Belgrade fell to him in 1521 and Rhodes in 1522–1523, and at Mohács in 1526, Suleiman broke the strength of the Kingdom of Hungary. Hungary was subsequently divided, with much of it incorporated directly into the empire. However, his defeat at the siege of Vienna in 1529 checked advances further into Europe.

The Tanzimat (Ottoman Turkish: تنظيمات, Turkish: Tanzimât, lit. 'Reorganization') was a period of reforms in the Ottoman Empire that began with the Edict of Gülhane of 1839 and ended with the First Constitutional Era in 1876. Driven by reformist statesmen such as Mustafa Reşid Pasha, Mehmed Emin Âli Pasha, and Fuad Pasha, under Sultans Abdul Mejid and Abdul Aziz, the reforms sought to reverse the empire's decline by modernizing legal, military, and administrative systems while promoting Ottomanism (equality for all subjects). Though secular courts, modern education, and infrastructure like railways, were introduced, the reforms faced resistance from conservative clerics, exacerbated ethnic tensions in the Balkans, and saddled the empire with crippling foreign debt. The Tanzimat’s legacy remains contested: some historians credit it with establishing a powerful national government, while others argue it accelerated imperial fragmentation.

Different functions of government received reform, were completely reorganized, or started from scratch. Among institutions that received significant attention throughout this period included legislative functions, trade policy, secularization and codification of the legal system, crackdowns on the slave trade, education, property law, law enforcement, and the military. Ottoman statesmen also worked with reformers of the many confessional communities of the empire, millets, to codify — and in some cases democratize — their confessional governments.

Imbros (Greek: Ίμβρος, romanized: Ímvros; Turkish: İmroz; Ottoman Turkish: ايمروز), officially Gökçeada (lit. 'Heavenly Island') since 29 July 1970, is the largest island of Turkey, located in Çanakkale Province. It is located in the north-northeastern Aegean Sea, at the entrance of Saros Bay, and has the westernmost point of Turkey (Cape İncirburnu). Imbros has an area of 286.8 km (110.7 sq mi), and has some wooded areas.

As of 2023, the island-district of Gökçeada has a population of 10,721. The main industries of Imbros are fishing and tourism. By the end of the 20th century, the island was predominantly inhabited by settlers from the Turkish mainland that mostly arrived after 1960, with the indigenous Greek population having declined to about 300 persons by the start of the 21st century.

Jalāl al-Dīn Muḥammad Rūmī (Persian: جلال‌الدین محمّد رومی), or simply Rumi (30 September 1207 – 17 December 1273), was a Sufi mystic and poet whose followers went on to found the Mevlevi Order most famous for its whirling dervishes – a practice that he instigated. Rumi is a seminal figure in Sufism, or mystical Islam, whose thought and works loom large in both Persian literature and mystic poetry in general, with his translated works being enjoyed globally to this day.

Rumi's works are written in his mother tongue, Persian. He occasionally used the Arabic language and single Turkish and Greek words in his verse. His Masnavi (Mathnawi), composed in Konya, is considered one of the greatest poems of the Persian language. Rumi's influence has transcended national borders and ethnic divisions: Iranians, Afghans, Tajiks, Turks, Kurds, Greeks, Central Asian Muslims, as well as Muslims of the Indian subcontinent have greatly appreciated his spiritual legacy for the past seven centuries. His poetry influenced not only Persian literature, but also the literary traditions of the Ottoman Turkish, Chagatai, Pashto, Kurdish, Urdu, and Bengali languages.

The Khedivate of Egypt (Arabic: الْخُدَيْوِيَّةُ الْمِصْرِيَّةُ or خُدَيْوِيَّةُ مِصْرَ, Egyptian Arabic pronunciation: [xedeˈwejjet mɑsˤɾ]; Ottoman Turkish: خدیویت مصر Hıdiviyet-i Mısır) was an autonomous tributary state of the Ottoman Empire established and ruled by the Muhammad Ali Dynasty following the defeat and expulsion of Napoleon Bonaparte's forces, ending the short-lived French occupation of Lower Egypt. The Khedivate of Egypt had also expanded to control present-day Sudan, South Sudan, Eritrea, Djibouti, northwestern Somalia, northeastern Ethiopia, Lebanon, Jordan, Israel, Palestine, Syria, Greece, Cyprus, southern and central Turkey, in addition to parts from Libya, Chad, Central African Republic, Democratic Republic of Congo, and Uganda, as well as northwestern Saudi Arabia, parts of Yemen and the Kingdom of Hejaz.

The United Kingdom invaded and took control in 1882. In 1914, the Ottoman Empire connection was ended and Britain established a protectorate called the Sultanate of Egypt.

Turkish (Türkçe [ˈtyɾktʃe], Türk dili, also known as Türkiye Türkçesi 'Turkish of Turkey') is the most widely spoken of the Turkic languages with around 90 million speakers. It is the national language of Turkey and one of two official languages of Cyprus. Significant smaller groups of Turkish speakers also exist in Germany, Austria, Bulgaria, North Macedonia, Greece, other parts of Europe, the South Caucasus, and some parts of Central Asia, Iraq, and Syria. Turkish is the 18th-most spoken language in the world.

To the west, the influence of Ottoman Turkish—the variety of the Turkish language that was used as the administrative and literary language of the Ottoman Empire—spread as the Ottoman Empire expanded. In 1928, as one of Atatürk's reforms in the early years of the Republic of Turkey, the Perso-Arabic script-based Ottoman Turkish alphabet was replaced with the Latin script-based Turkish alphabet.

Botev Peak (Bulgarian: (връх) Ботев Bulgarian pronunciation: [(vrɤx) ˈbɔtɛf]) is, at 2,376 metres (7,795 ft) above sea level, the highest peak of the Balkan Mountains in southeastern Europe. It is located close to the geographic centre of Bulgaria, and is part of the Central Balkan National Park.

Until 1950, when it was renamed in honour of Bulgarian poet and revolutionary Hristo Botev, the peak was called Yumrukchal (Юмрукчал, from Ottoman Turkish Yumrukçal, 'a fist-like peak').

The Ottoman Turkish alphabet (Ottoman Turkish: الفبا, romanized: elifbâ) is a version of the Perso-Arabic script used to write Ottoman Turkish for over 600 years until 1928, when it was replaced by the Latin-based modern Turkish alphabet.

Though Ottoman Turkish was primarily written in this script, non-Muslim Ottoman subjects sometimes wrote it in other scripts, including Armenian, Greek, Latin and Hebrew alphabets.

Osman I or as he is known, Osman Gazi or Osman Bey.(Ottoman Turkish: عثمان غازى , عثمان بك, romanized: ʿOsmān Ġāzī; Turkish: I. Osman or Osman Gazi; died 1323/4) was the eponymous founder of the Ottoman Empire (first known as a beylik or emirate). While initially a small Turkoman principality during Osman's lifetime, his beylik transformed into a vast empire in the centuries after his death. It existed until 1922 shortly after the end of World War I, when the sultanate was abolished.

Owing to the scarcity of historical sources dating from his lifetime, very little factual information about Osman has survived. Not a single written source survives from Osman's reign, and the Ottomans did not record the history of his life until the fifteenth century, more than a hundred years after his death. Because of this, historians find it very challenging to differentiate between fact and myth in the many stories told about him. One historian has even gone so far as to declare it impossible, describing the period of Osman's life as a "black hole".

In the Ottoman Empire, a millet (Turkish: [millet]; Ottoman Turkish: ملت, Arabic: مِلَّة) was an independent court of law pertaining to "personal law" under which a confessional community (a group abiding by the laws of Muslim sharia, Christian canon law, or Jewish halakha) was allowed to rule itself under its own laws.

Despite frequently being referred to as a "system", before the nineteenth century the organization of what are now retrospectively called millets in the Ottoman Empire was not at all systematic. Rather, non-Muslims were simply given a significant degree of autonomy within their own community, without an overarching structure for the millet as a whole. The notion of distinct millets corresponding to different religious communities within the empire would not emerge until the eighteenth century. Subsequently, the millet system was justified through numerous foundation myths linking it back to the time of Sultan Mehmed the Conqueror (r. 1451–81), although it is now understood that no such system existed in the fifteenth century. Heads of millets, or milletbaşı (Ethnarch), usually had absolute secular and ecclesiastical power over their communities, being answerable only to the Sultan.

The Enderun School (Ottoman Turkish: اندرون مکتب, romanized: Enderûn Mektebi) was a palace school and boarding school within Topkapi Palace. It was mostly for princes of the court and the Janissaries of the Ottoman Empire. Students here were primarily recruited via devşirme, a system of the Islamization of Christian slave children for serving the Ottoman government in bureaucratic, managerial, and Janissary military positions. Over the centuries, the Enderun School was fairly successful in generating Ottoman statesmen by drawing among the empire's various ethnic groups and giving them a common Muslim education. The school was run by the "Inner Service" (Enderûn) of the Ottoman palace and had both academic and military purposes. The graduates were expected to devote themselves to government service and be free of links to lower social groups.

The Enderun School's gifted education program has been called the world's first institutionalized education for the gifted.

Murad II (Ottoman Turkish: مراد ثانى, romanized: Murād-ı sānī, Turkish: II. Murad; June 1404 – 3 February 1451) was twice the sultan of the Ottoman Empire, from 1421 to 1444 and from 1446 to 1451.

Sanjak-bey, sanjaq-bey or -beg (Ottoman Turkish: سنجاق بك, lit. 'lord of the standard') was the title given in the Ottoman Empire to a bey (a high-ranking officer, but usually not a pasha) appointed to the military and administrative command of a district (sanjak, in Arabic liwa’), hence the equivalent Arabic title of amir liwa (أمير لواء ’amīr liwā’) He was answerable to a superior wāli or another provincial governor. In a few cases the sanjak-bey was himself directly answerable to the sultan in Constantinople.

Like other early Ottoman administrative offices, the sanjak-bey had a military origin: the term sanjak (and liva) means "flag" or "standard" and denoted the insigne around which, in times of war, the cavalrymen holding fiefs (timars or ziamets) in the specific district gathered. The sanjakbey was in turn subordinate to a beylerbey ("bey of beys") who governed an eyalet and commanded his subordinate sanjak-beys in war. In this way, the structure of command on the battlefield resembled the hierarchy of provincial government.

The Albanian Vilayet (Ottoman Turkish: ولايت ارناود, Vilâyet-i Arnavid) was a projected vilayet of the Ottoman Empire in the western Balkan Peninsula, which was to include the four Ottoman vilayets with substantial ethnic Albanian populations: Kosovo Vilayet, Scutari Vilayet, Manastir Vilayet, and Janina Vilayet. In some proposals, it included the Salonica Vilayet as well. The creation of the Vilayet was confirmed in September 1912, but negotiations were interrupted a month later in October by the beginning of the First Balkan War. Plans for an Albanian Vilayet were lost with the Partition of Albania.

A separate Albanian vilayet was a part of the agenda of many Albanian organizations and societies since 1877, during the period known as the Albanian National Awakening. Establishment of such a vilayet was agreed between the Albanian rebels and the authorized representatives of the Ottoman government on 4 September 1912, following the Albanian Revolt of 1912. Soon after that agreement however, the First Balkan War broke out and most of the remaining European territory of the Ottoman Empire was occupied by the Balkan League member states. After the army of the Kingdom of Serbia captured Skopje, Ismail Qemali invited a group of Albanians from all four Ottoman vilayets that were agreed to be united into the Albanian Vilayet, to attend an All-Albanian Congress in Valona. There they declared independence on 28 November 1912, and set up the Provisional Government of Albania.
