1Anatolian Beyliks

As the Seljuk Sultanate of Rum declined in the 13th century, Anatolia was divided into a patchwork of independent Turkish principalities known as the Anatolian Beyliks. One of these beyliks, in the region of Bithynia on the frontier of the Byzantine Empire, was led by the Turkish tribal leader Osman I, a figure of obscure origins from whom the name Ottoman is derived.

2Battle of Bapheus

Osman extended the control of his principality by conquering Byzantine towns along the Sakarya River. A Byzantine defeat at the Battle of Bapheus in 1302 contributed to Osman's rise as well. It is not well understood how the early Ottomans came to dominate their neighbors, due to the lack of sources surviving from this period.

3Orhan captured Bursa

Osman's son, Orhan, captured the northwestern Anatolian city of Bursa in 1326, making it the new capital of the Ottoman state and supplanting Byzantine control in the region.

4Thessaloniki was captured by the Venetians

The important port city of Thessaloniki was captured by the Venetians in 1387 and sacked.

5Battle of Kosovo

The Ottoman victory in Kosovo in 1389 effectively marked the end of Serbian power in the region, paving the way for Ottoman expansion into Europe.

6Battle of Nicopolis

The Battle of Nicopolis for the Bulgarian Tsardom of Vidin in 1396, widely regarded as the last large-scale crusade of the Middle Ages, failed to stop the advance of the victorious Ottoman Turks.

7Byzantines were temporarily relieved when the Turco-Mongol leader Timur

In 1402, the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Ottoman Anatolia from the east.

8Battle of Ankara

In the Battle of Ankara in 1402, Timur defeated the Ottoman forces and took Bayezid I as a prisoner, throwing the empire into disorder.

9Ottoman Interregnum

The ensuing civil war, also known as the Fetret Devri, lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power.

10Battle of Varna

On 10 November 1444, Murad II repelled the Crusade of Varna by defeating the Hungarian, Polish, and Wallachian armies under Władysław III of Poland (also King of Hungary) and John Hunyadi at the Battle of Varna, although Albanians under Skanderbeg continued to resist.

11Second Battle of Kosovo

Four years later, John Hunyadi prepared another army of Hungarian and Wallachian forces to attack the Turks but was again defeated at the Second Battle of Kosovo in 1448.

12Mehmed the Conqueror conquered Constantinople

The son of Murad II, Mehmed the Conqueror, reorganized both state and military, and on 29 May 1453 conquered Constantinople, ending the Byzantine Empire. Mehmed allowed the Eastern Orthodox Church to maintain its autonomy and land in exchange for accepting Ottoman authority.

13Battle of Chaldiran

Sultan Selim I (1512–1520) dramatically expanded the Empire's eastern and southern frontiers by defeating Shah Ismail of Safavid Iran, in the Battle of Chaldiran.

14Selim I established Ottoman rule in Egypt

Selim I established Ottoman rule in Egypt by defeating and annexing the Mamluk Sultanate of Egypt and created a naval presence on the Red Sea.

15Suleiman the Magnificent captured Belgrade

Suleiman the Magnificent (1520–1566) captured Belgrade in 1521.

16Battle of Mohács

Suleiman the Magnificent conquered the southern and central parts of the Kingdom of Hungary as part of the Ottoman–Hungarian Wars, and, after his historic victory in the Battle of Mohács in 1526, he established Ottoman rule in the territory of present-day Hungary (except the western part) and other Central European territories.

17Suleiman the Magnificent failed to take Vienna

Suleiman the Magnificent then laid siege to Vienna in 1529 but failed to take the city.

18Siege of Güns

In 1532, Suleiman the Magnificent made another attack on Vienna but was repulsed in the Siege of Güns.

19Ottomans took Baghdad

In the east, the Ottoman Turks took Baghdad from the Persians in the 1530s, gaining control of Mesopotamia and naval access to the Persian Gulf.

20Siege of Castelnuovo

In 1539, a 60,000-strong Ottoman army besieged the Spanish garrison of Castelnuovo on the Adriatic coast; the successful siege cost the Ottomans 8,000 casualties, but Venice agreed to terms in 1540, surrendering most of its empire in the Aegean and the Morea. France and the Ottoman Empire, united by mutual opposition to Habsburg rule, became strong allies.

21Joint Venture

The French conquests of Nice (1543) and Corsica (1553) occurred as a joint venture between the forces of the French king Francis I and Suleiman, and were commanded by the Ottoman admirals Barbarossa Hayreddin Pasha and Turgut Reis.

22Siege of Esztergom

A month before the siege of Nice, France supported the Ottomans with an artillery unit during the 1543 Ottoman conquest of Esztergom in northern Hungary. After further advances by the Turks, the Habsburg ruler Ferdinand officially recognized Ottoman ascendancy in Hungary in 1547.

23Caucasus became officially partitioned for the first time between the Safavids and the Ottomans

In 1555, the Caucasus became officially partitioned for the first time between the Safavids and the Ottomans, a status quo that would remain until the end of the Russo-Turkish War (1768–1774). By this partitioning of the Caucasus as signed in the Peace of Amasya, Western Armenia, western Kurdistan, and Western Georgia (incl. western Samtskhe) fell into Ottoman hands, while southern Dagestan, Eastern Armenia, Eastern Georgia, and Azerbaijan remained Persian.

24Great Siege of Malta

It was startling, if mostly symbolic, blow to the image of Ottoman invincibility, an image which the victory of the Knights of Malta against the Ottoman invaders in the 1565 Siege of Malta had recently set about eroding.

25Suleiman I died

Suleiman I died of natural causes in his tent during the Siege of Szigetvár in 1566.

26Ottomans decided to conquer Venetian Cyprus

The Ottomans decided to conquer Venetian Cyprus and on 22 July 1570, Nicosia was besieged; 50,000 Christians died, and 180,000 were enslaved.

27Fall of Famagusta

On 17 September 1570, the Ottoman cavalry appeared before the last Venetian stronghold in Cyprus, Famagusta. The Venetian defenders would hold out for 11 months against a force that would come to number 200,000 men with 145 cannons; 163,000 cannonballs struck the walls of Famagusta before it fell to the Ottomans in August 1571. The Siege of Famagusta claimed 50,000 Ottoman casualties.

28Fire of Moscow (1571)

In 1571, the Crimean khan Devlet I Giray, commanded by the Ottomans, burned Moscow.

29Battle of Lepanto

Meanwhile, the Holy league consisting of mostly Spanish and Venetian fleets won a victory over the Ottoman fleet at the Battle of Lepanto (1571), off southwestern Greece; Catholic forces killed over 30,000 Turks and destroyed 200 of their ships.

30Battle of Molodi

The next year, the invasion was repeated but repelled at the Battle of Molodi. The Ottoman Empire continued to invade Eastern Europe in a series of slave raids and remained a significant power in Eastern Europe until the end of the 17th century.

31Treaty of Nasuh Pasha

In spite of these problems, the Ottoman state remained strong, and its army did not collapse or suffer crushing defeats. The only exceptions were campaigns against the Safavid dynasty of Persia, where many of the Ottoman eastern provinces were lost, some permanently. This 1603–1618 war eventually resulted in the Treaty of Nasuh Pasha, which ceded the entire Caucasus, except westernmost Georgia, back into Iranian Safavid possession.

32Treaty of Zuhab

The resulting Treaty of Zuhab of that same year decisively divided the Caucasus and adjacent regions between the two neighboring empires (Safavid Empire and the Ottoman Empire) as it had already been defined in the 1555 Peace of Amasya.

33Murad IV recaptured Iraq

During his brief majority reign, Murad IV (1623–1640) reasserted central authority and recaptured Iraq (1639) from the Safavids.

34Kösem's murder

The Sultanate of Women (1533–1656) was a period in which the mothers of young sultans exercised power on behalf of their sons. The most prominent women of this period were Kösem Sultan and her daughter-in-law Turhan Hatice, whose political rivalry culminated in Kösem's murder in 1651.

35Battle of Vienna

This period of renewed assertiveness came to a calamitous end in 1683 when Grand Vizier Kara Mustafa Pasha led a huge army to attempt a second Ottoman siege of Vienna in the Great Turkish War of 1683–1699. The final assault being fatally delayed, the Ottoman forces were swept away by allied Habsburg, German, and Polish forces spearheaded by the Polish king John III Sobieski at the Battle of Vienna.

36Defeat at Zenta

Mustafa II (1695–1703) led the counterattack of 1695–1696 against the Habsburgs in Hungary but was undone at the disastrous defeat at Zenta (in modern Serbia), 11 September 1697.

37Treaty of Karlowitz

The alliance of the Holy League pressed home the advantage of the defeat at Vienna, culminating in the Treaty of Karlowitz (26 January 1699), which ended the Great Turkish War. The Ottomans surrendered control of significant territories, many permanently.

38Battle of Poltava

Accordingly, King Charles XII of Sweden was welcomed as an ally in the Ottoman Empire following his defeat by the Russians at the Battle of Poltava of 1709 in central Ukraine (part of the Great Northern War of 1700–1721).

39Treaty of Passarowitz

After the Austro-Turkish War of 1716–1718, the Treaty of Passarowitz confirmed the loss of the Banat, Serbia, and "Little Walachia" (Oltenia) to Austria. The Treaty also revealed that the Ottoman Empire was on the defensive and unlikely to present any further aggression in Europe.

40Efficiency of the printing press

In 1726, Ibrahim Muteferrika convinced the Grand Vizier Nevşehirli Damat İbrahim Pasha, the Grand Mufti, and the clergy on the efficiency of the printing press, and Muteferrika was later granted by Sultan Ahmed III permission to publish non-religious books (despite opposition from some calligraphers and religious leaders).

41Spain conquered Oran

In Ottoman North Africa, Spain conquered Oran from the Ottoman Empire (1732). The bey received an Ottoman army from Algiers, but it failed to recapture Oran; the siege caused the deaths of 1,500 Spaniards and even more Algerians.

42Treaty of Belgrade

The Austro-Russian–Turkish War (1735–1739), which was ended by the Treaty of Belgrade in 1739, resulted in the Ottoman recovery of northern Bosnia, Habsburg Serbia (including Belgrade), Oltenia, and the southern parts of the Banat of Temeswar; but the Empire lost the port of Azov, north of the Crimean Peninsula, to the Russians. After this treaty, the Ottoman Empire was able to enjoy a generation of peace, as Austria and Russia were forced to deal with the rise of Prussia.

43Istanbul Technical University

Educational and technological reforms came about, including the establishment of higher education institutions such as the Istanbul Technical University.

44Treaty of Küçük Kaynarca

This action (Battle of Balta) provoked the Ottoman Empire into the Russo-Turkish War of 1768–1774. The Treaty of Küçük Kaynarca of 1774 ended the war and provided freedom of worship for the Christian citizens of the Ottoman-controlled provinces of Wallachia and Moldavia.

45Ukrainian Haidamakas entered Balta

In 1768 Russian-backed Ukrainian Haidamakas, pursuing Polish confederates, entered Balta, an Ottoman-controlled town on the border of Bessarabia in Ukraine, massacred its citizens, and burned the town to the ground. This action provoked the Ottoman Empire into the Russo-Turkish War of 1768–1774.

46Selim III made the first major attempts to modernize the army

Selim III (1789–1807) made the first major attempts to modernize the army, but his reforms were hampered by the religious leadership and the Janissary corps. Jealous of their privileges and firmly opposed to change, the Janissary revolted. Selim's efforts cost him his throne and his life but were resolved in spectacular and bloody fashion by his successor, the dynamic Mahmud II, who eliminated the Janissary corps in 1826.

47Serbian Revolution

The Serbian revolution (1804–1815) marked the beginning of an era of national awakening in the Balkans during the Eastern Question.

48Al-Saud family revolted against the Ottomans

In 1811, the fundamentalist Wahhabis of Arabia, led by the al-Saud family, revolted against the Ottomans. Unable to defeat the Wahhabi rebels, the Sublime Porte had Muhammad Ali Pasha of Kavala, the vali (governor) of the Eyalet of Egypt, tasked with retaking Arabia, which ended with the destruction of the Emirate of Diriyah in 1818. The suzerainty of Serbia as a hereditary monarchy under its own dynasty was acknowledged de jure in 1830.

49Greeks declared war on the Sultan

In 1821, the Greeks declared war on the Sultan. A rebellion that originated in Moldavia as a diversion was followed by the main revolution in the Peloponnese, which, along with the northern part of the Gulf of Corinth, became the first part of the Ottoman Empire to achieve independence (in 1829).

50French invaded Ottoman Algeria

In 1830, the French invaded Ottoman Algeria.

51Muhammad Ali Pasha revolted against Sultan Mahmud II

In 1831, Muhammad Ali Pasha revolted against Sultan Mahmud II due to the latter's refusal to grant him the governorships of Greater Syria and Crete, which the Sultan had promised him in exchange for sending military assistance to put down the Greek revolt (1821–1829) that ultimately ended with the formal independence of Greece in 1830.

52320 km from the capital, Constantinople

Thus began the first Egyptian–Ottoman War (1831–1833), during which the French-trained army of Muhammad Ali Pasha, under the command of his son Ibrahim Pasha, defeated the Ottoman Army as it marched into Anatolia with a great victory, reaching the city of Kütahya within 320 km (200 mi) of the capital, Constantinople.

53Begging for help

In desperation, the defeated Sultan Mahmud II appealed to the empire's traditional arch-rival Russia for help, asking Emperor Nicholas I to send an expeditionary force to assist him and to save his reign. In return for signing the Treaty of Hünkâr İskelesi, the Russians sent the expeditionary force which deterred Ibrahim Pasha from marching any further towards Constantinople.

54Convention of Kütahya

Under the terms of the Convention of Kütahya, signed on 5 May 1833, Muhammad Ali Pasha agreed to abandon his campaign against the Sultan, in exchange for which he was made the vali (governor) of the vilayets (provinces) of Crete, Aleppo, Tripoli, Damascus and Sidon (the latter four comprising modern Syria and Lebanon), and given the right to collect taxes in Adana.

55Sublime Porte attempted to take back what it lost to the de facto autonomous

In 1839, the Sublime Porte attempted to take back what it lost to the de facto autonomous, but de jure still Ottoman Eyalet of Egypt, but its forces were initially defeated, which led to the Oriental Crisis of 1840. Muhammad Ali Pasha had close relations with France, and the prospect of him becoming the Sultan of Egypt was widely viewed as putting the entire Levant into the French sphere of influence.

56Second Egyptian–Ottoman War

Sublime Porte had proved itself incapable of defeating Muhammad Ali Pasha, the British Empire and Austrian Empire provided military assistance, and the second Egyptian–Ottoman War (1839–1841) ended with Ottoman victory and the restoration of Ottoman suzerainty over Egypt Eyalet and the Levant.

57Sick man of Europe

By the mid-19th century, the Ottoman Empire was called the "sick man of Europe". Three suzerain states – the Principality of Serbia, Wallachia, and Moldavia – moved towards de jure independence during the 1860s and 1870s.

58Foreign Loans

The Crimean War (1853–1856) was part of a long-running contest between the major European powers for influence over territories of the declining Ottoman Empire. The financial burden of the war led the Ottoman state to issue foreign loans amounting to 5 million pounds sterling on 4 August 1854.

59Bankruptcy declaration

The Ottoman state, which had begun taking on debt with the Crimean War, was forced to declare bankruptcy in 1875.

60Massacring up to 100,000 people

The Ottoman bashi-bazouks brutally suppressed the Bulgarian uprising of 1876, massacring up to 100,000 people in the process.

61Lost the Russo-Turkish War

The Russo-Turkish War (1877–1878) ended with a decisive victory for Russia. As a result, Ottoman holdings in Europe declined sharply: Bulgaria was established as an independent principality inside the Ottoman Empire; Romania achieved full independence, and Serbia and Montenegro finally gained complete independence, but with smaller territories.

62Austria-Hungary unilaterally occupied the Ottoman provinces

In 1878, Austria-Hungary unilaterally occupied the Ottoman provinces of Bosnia-Herzegovina and Novi Pazar.

63Ottoman Public Debt Administration

By 1881, the Ottoman Empire agreed to have its debt controlled by an institution known as the Ottoman Public Debt Administration, a council of European men with a presidency alternating between France and Britain. The body controlled swaths of the Ottoman economy and used its position to ensure that European capital continued to penetrate the empire, often to the detriment of local Ottoman interests.

64Coward Damned

Britain later sent troops to Egypt in 1882 to put down the Urabi Revolt – Sultan Abdul Hamid II was too paranoid to mobilize his own army, fearing this would result in a coup d'état – effectively gaining control in both territories. Abdul Hamid II, popularly known as "Abdul Hamid the Damned" on account of his cruelty and paranoia, was so fearful of the threat of a coup that he did not allow his army to conduct war games, lest this serves as the cover for a coup, but he did see the need for military mobilization.

65Goltz generation

In 1883, a German military mission under General Baron Colmar von der Goltz arrived to train the Ottoman Army, leading to the so-called "Goltz generation" of German-trained officers who were to play a notable role in the politics of the last years of the empire.

66Hamidian massacres

From 1894 to 1896, between 100,000 and 300,000 Armenians living throughout the empire were killed in what became known as the Hamidian massacres.

67Young Turk Revolution

The Young Turk Revolution (July 1908) was a constitutionalist revolution in the Ottoman Empire. The Committee of Union and Progress (CUP), an organization of the Young Turks movement, forced Sultan Abdulhamid II to restore the Ottoman Constitution and recall the parliament, which ushered in multi-party politics within the Empire.

68Austria-Hungary officially annexed Bosnia and Herzegovina

Austria-Hungary officially annexed Bosnia and Herzegovina in 1908.

69Armenian genocide

In 1915 the Ottoman government and Kurdish tribes in the region started the extermination of its ethnic Armenian population, resulting in the death of up to 1.5 million Armenians in the Armenian genocide.

70Arab Revolt

The Arab Revolt began in 1916 with British support. It turned the tide against the Ottomans on the Middle Eastern front, where they seemed to have the upper hand during the first two years of the war. On the basis of the McMahon–Hussein Correspondence, an agreement between the British government and Hussein bin Ali, Sharif of Mecca, the revolt was officially initiated at Mecca on 10 June 1916.

71Armistice of Mudros

Defeated on every front, the Ottoman Empire signed the Armistice of Mudros on 30 October 1918.

72Constantinople was occupied

Constantinople was occupied by combined British, French, Italian, and Greek forces.

73Turkish War of Independence

There arose a nationalist opposition in the Turkish national movement. It won the Turkish War of Independence (1919–1923) under the leadership of Mustafa Kemal (later given the surname "Atatürk").

74Treaty of Sèvres

The partition of the Ottoman Empire was finalized under the terms of the 1920 Treaty of Sèvres. This treaty, as designed in the Conference of London, allowed the Sultan to retain his position and title. The status of Anatolia was problematic given the occupied forces.

75Sultanate was abolished

The sultanate was abolished on 1 November 1922.

76Last Sultan left the country

Last Sultan, Mehmed VI (reigned 1918–1922), left the country on 17 November 1922.

77Republic of Turkey was established

The Republic of Turkey was established in its place on 29 October 1923, in the new capital city of Ankara.
