Ottoman Empire

Overview

The Ottoman Empire was a dynastic state founded in northwestern Anatolia under Osman I around 1299. Over six centuries, its rulers built an empire linking southeastern Europe, Anatolia, North Africa and the Middle East. Ottoman armies took Constantinople in 1453 and Jerusalem in 1517. From its capital in Constantinople, later known as Istanbul, the state governed populations speaking many languages and practicing several religions. Its provinces encompassed the Land of Israel for four centuries, until British forces took Jerusalem in 1917.

The empire combined central authority with varied local arrangements. Sultans appointed governors, collected taxes and maintained armies, while provincial notables, religious leaders and local rulers exercised authority under imperial oversight. Ottoman policy changed substantially across time and place: periods of relative security and communal autonomy coexisted with heavy taxation, coercion, rebellion and, in the empire’s final years, mass atrocities. Its history cannot be reduced either to uniform tolerance or to a single pattern of oppression.

Ottoman power shaped cities, trade routes, religious institutions and borders far beyond present-day Turkey. Acre, İzmir, Baghdad and Jerusalem belonged to imperial networks connecting the Mediterranean with inland Asia. Cyprus and Libya also came under Ottoman rule; Libya remained under Ottoman sovereignty from 1551 until 1911, including a period of largely autonomous rule by the Qaramanlı dynasty. The empire’s defeat in World War I ended this political order and opened a struggle over its territories and successor states.

Rise

Osman I established the state’s foundations around 1299 on the Byzantine frontier of northwestern Anatolia. His successors expanded into the Balkans and consolidated control over neighboring Turkish principalities. Conquest brought land, revenue and manpower, while a developing court and military administration turned a frontier polity into a durable state. Bursa and then Edirne served as capitals before Constantinople became the empire’s political center. Ottoman expansion was neither continuous nor uncontested, but the dynasty recovered from defeats and built institutions capable of sustaining further campaigns.

In 1453, Sultan Mehmed II captured Constantinople from the Byzantine emperor, ending Byzantine control of the city. He made it his capital and developed it as an imperial center. The city’s Hagia Sophia, built as a Byzantine church, became a mosque after the conquest. Constantinople’s position between Europe and Asia gave the Ottomans command of a major crossroads for government, commerce and military movement. Its population included communities of different languages and faiths, making the capital a visible expression of the empire’s reach.

In the early sixteenth century, Sultan Selim I defeated the Mamluks and extended Ottoman control into Syria, Egypt and the Land of Israel. Ottoman forces took Jerusalem in 1517, beginning four centuries of imperial rule there. Selim’s campaigns also brought Mosul under Ottoman authority with Kurdish assistance. During the Ottoman–Safavid struggle, Kurdish diplomat Idris Betlis persuaded numerous Kurdish princes to transfer allegiance to Istanbul; princes of Soran and Cizre seized Kirkuk and Mosul in the Ottomans’ name. These alliances helped secure eastern provinces while leaving considerable authority in local hands.

Under Suleyman I, who reigned from 1520 to 1566, Ottoman power extended across much of the eastern Mediterranean and into central Europe. The empire governed territory in present-day Iraq and Yemen, while contesting the Safavid state centered in Iran. Suleyman’s reign combined military expansion with legislation, administration and monumental building. In Jerusalem he ordered the restoration of the city walls, work begun in the 1530s that still defines the Old City’s appearance. Ottoman competition with European states also continued at sea; a European coalition defeated a numerically superior Ottoman fleet at Lepanto in 1571 without ending Ottoman power in the Mediterranean.

Rule and society

Ottoman rule depended on provincial administration as well as military force. Governors, judges and tax collectors represented the sultan, but practical authority often rested with local families, tribal leaders and religious institutions. In parts of Syria, the government recognized existing leaders: after the conquest of 1516, Selim I confirmed Fakhr al-Din as a Druze emir with local authority. Control could be uneven at the empire’s margins. In eastern Lower Galilee, Ottoman authorities sought to strengthen their position by settling migrants from Algiers and sending Kurdish battalions against Bedouin tribes before Circassian settlement took hold.

Jews and Christians could organize communal religious life under imperial supervision. The millet system gave recognized communities institutions for worship, education and aspects of personal status. Such autonomy did not confer equal standing with Muslims. Jews and Christians lived as dhimmis, a subordinate protected legal category, and were subject to jizya, a tax imposed on dhimmis under Islamic rule. Local practice, government policy and the power of individual officials affected how these rules operated. Religious communities maintained schools, courts and charitable networks, yet remained exposed to fiscal pressure and political upheaval.

The population of the Land of Israel changed during Ottoman rule. In 1831, Muhammad Ali of Egypt conquered the region, and thousands of Egyptians migrated there. During the nineteenth and early twentieth centuries, Jews, Circassians, Armenians, Europeans and others also arrived. Arab communities retained varied local, urban, clan, religious and broader regional identities. Jerusalem attracted European attention as Ottoman power weakened: foreign governments and churches built compounds and institutions, including the Austrian Hospice. Competition for influence added another layer to the city’s religious and political life.

Reform became a central concern in the nineteenth century. After losing Crimea to Russia in the late eighteenth century, Ottoman rulers began modernizing the military. Later Tanzimat reforms sought stronger central administration, revised laws and new schools and military institutions. The 1858 land law introduced registration in the tabu registry as a basis for legal title. Registration changed how ownership could be proved and transferred. NGO Monitor’s analysis of Bedouin claims notes that many Bedouin did not register land under Ottoman rule, leaving them without registered title under that system. These legal changes affected later disputes without erasing the history of land use.

Reform did not prevent territorial losses or foreign intervention. European powers competed for influence over Ottoman finances, trade and strategic routes. Near the Suez Canal, Britain pressed to move the Ottoman–Egyptian frontier farther from the waterway. In 1906, the Ottoman police commander at Um Rashrash, now Eilat, held out for Taba rather than Aqaba as the border’s starting point. That decision helped establish the line that became the international border between Israel and Egypt. The episode illustrates how local decisions within a weakening empire shaped later state boundaries.

Jews under its rule

Jewish communities had lived in the Land of Israel before the Ottoman conquest. Under Ottoman administration they remained in Jerusalem, Hebron, Gaza, Safed and other towns, joined by migrants from elsewhere in the empire and beyond. After the 1492 expulsion from Spain, Sephardi Jews settled across Ottoman territories and North Africa, joining older Jewish communities. Ottoman rulers offered opportunities for settlement and commerce, although conditions differed by province and period. In sixteenth-century Safed, Jewish immigration supported a major center of scholarship, religious thought and textile production.

Suleyman I encouraged Jews expelled from Spain and Portugal to settle in Jerusalem. After the 1546 earthquake, he ordered rubble beside the Western Wall cleared to create a Jewish prayer site. His reign brought substantial opportunities for Ottoman Jewish communities, including roles in trade and at court, alongside taxation and occasional compulsory resettlement. Don Solomon Ibn Ya’ish, who settled in Istanbul in 1580, served sultans Murad III and Mehmed III as a diplomat and customs farmer. By the early seventeenth century, Jews in İzmir maintained ties with communities across the empire.

Elsewhere, Ottoman control could improve conditions relative to preceding governments without guaranteeing security. Jews in Baghdad experienced oppression during periods of Persian rule amid the Ottoman–Safavid contest and received fairer treatment under Ottoman rule. Later Ottoman administrations in Baghdad became harsher in the late eighteenth and early nineteenth centuries. In Yemen, Ottoman rule beginning in the sixteenth century renewed Jewish contact with Kabbalists in Safed and other communities. When Ottoman rule returned in 1872, Yemenite Jews gained greater freedom of religious practice and wider contact abroad.

Jewish life also faced violence and official abuse. Ottoman authorities restored order and arrested rioters after attacks on Beirut’s Jewish quarter in 1890. During World War I, the Ottoman army drafted several thousand Iraqi Jews and sent them to distant fronts, from which many never returned. In 1917, officials in Baghdad blamed Jews for currency devaluation and subjected community members to extortion, torture and execution. After the war began, Ottoman authorities deported David Ben-Gurion and Yitzhak Ben-Zvi to Egypt on suspicion of supporting Jewish national independence. These episodes show the vulnerability of communities whose rights depended on a state under severe wartime strain.

The Jewish people’s return to its historic homeland developed during the empire’s final decades. Theodor Herzl sought support from Sultan Abdul Hamid II for that national movement, but the sultan did not grant his proposals. Jewish immigration and institution-building continued as Ottoman sovereignty weakened. During World War I, Jewish volunteers fought alongside British forces against the Ottomans. In 1918, Chaim Weizmann initiated a medal for Jewish Legion soldiers bearing the words “Judea is liberated.” The later Balfour Declaration belonged to the wartime transition from Ottoman rule to British administration.

Decline

By the early twentieth century, military setbacks, territorial losses, debt and nationalist movements had weakened the empire. The Young Turks, a secular nationalist movement, came to dominate its late government. Their reform program did not end authoritarian rule or prevent violence against minorities. In 1913, a German military mission under Liman von Sanders began reorganizing Ottoman armed forces, alarming Russia. German warships sheltered by the Ottomans heightened friction with Britain, France and Russia as European war approached.

War minister Enver Pasha helped drive the decision to join Germany and Austria-Hungary, encouraged by Germany’s early victories. Only five Ottoman leaders knew of the secret alliance signed in August 1914. The empire formally entered World War I on October 28, 1914, when Ottoman warships bombarded Russian Black Sea ports. The Allied Powers declared war in early November. On November 14, the Ottoman government proclaimed armed jihad, calling for action against Britain, France, Russia, Serbia and Montenegro. Jihad means struggle or effort; this wartime declaration specifically urged armed warfare against named enemies.

The war reached communities throughout the empire. Ottoman authorities expelled British, French and Russian nationals and missionaries from Beirut and Mount Lebanon. Jamal Pasha, the military governor of Greater Syria, curtailed Mount Lebanon’s autonomy amid persecution and forced starvation affecting Maronites. In March 1915, authorities arrested Father Youssef al Hayek over correspondence with French political leader Paul Deschanel; Jamal Pasha later ordered him hanged. Christian suffering extended beyond a single province or community. Massacres by Turkish and Kurdish forces drove survivors toward safer areas, including the Nineveh Plains.

In 1915, the Young Turk government began the Armenian genocide by arresting and executing Armenian intellectuals. Authorities then removed families from their homes and forced them on death marches. The campaign included expropriation, abduction, torture and mass killing; approximately 1.5 million Armenians died. Greeks, Assyrians, Chaldeans and other Christian communities were also targeted by massacres and deportations. On July 16, 1915, U.S. ambassador Henry Morgenthau Sr. warned Washington that eyewitness accounts showed a campaign to exterminate Armenians. The arrests, deportations and killings establish the genocide’s character.

Britain and France planned for an Ottoman defeat while fighting continued. In May 1916, diplomats Mark Sykes and François Georges-Picot concluded the secret Sykes–Picot Agreement concerning the postwar future of Mesopotamia and the Levant. Their proposed spheres rested on the assumption that Ottoman territories would be partitioned. Britain also made wartime promises to Sharif Hussein in return for support against the empire. The later settlement did not produce one kingdom for him: his sons Abdullah and Faisal received Transjordan and Iraq. A separate December 1915 agreement made lands held by the House of Saud a British protectorate while Ibn Saud pledged renewed war against the Ottoman-allied Ibn Rashid.

Ottoman forces suffered severe defeats in the Middle East. British General Edmund Allenby took Jerusalem from the Ottoman Empire and its German ally in December 1917. Mayor Hussein al-Husayni surrendered the city; several confused preliminary encounters preceded Allenby’s official entry on foot through Jaffa Gate on December 11. Farther east, British and Ottoman forces contested Iraq and the Caucasus. Turkish forces retook Kirkuk two weeks after its capture in May 1918 and persecuted Jews who had been unable to leave. Ottoman forces also exploited the upheaval following the Bolshevik revolution in the Caucasus, but these gains could not reverse the empire’s wider collapse.

Ottoman representatives signed the 1918 armistice with the victorious powers, ending the empire’s participation in the war. Its terms enabled British, French and Greek forces to occupy parts of Ottoman territory, including areas they considered security threats. The 1920 Treaty of Sèvres proposed a far-reaching postwar settlement. The Turkish National Movement overturned it through military victories, and the 1923 Treaty of Lausanne replaced it. The sultanate had been abolished in 1922; the Republic of Turkey followed in 1923, and Mustafa Kemal Atatürk abolished the caliphate in 1924. These changes completed the fall of the Ottoman Empire.

Legacy

Ottoman institutions remained influential after the dynasty’s end. Land registries, religious communal arrangements, provincial boundaries and administrative practices shaped successor governments. The empire’s division also reshaped Kurdistan: Kurdish lands came under the authority of Turkey, Iraq, Iran and Syria, frustrating aspirations for a unified Kurdish state. In Jerusalem, Suleyman’s walls and Ottoman-era buildings remain prominent. In Israel and neighboring countries, questions about land records, borders and communal institutions still require attention to Ottoman decisions rather than assumptions about an unchanging past.

The Turkish Republic inherited both Ottoman institutions and the consequences of imperial defeat. Atatürk had been a decorated Ottoman commander, educated and trained in institutions developed before the republic. His reforms therefore followed earlier efforts at military and administrative modernization even as he abolished the sultanate’s remaining religious institution. Sèvres acquired enduring symbolic force in Turkish politics: fear that foreign powers seek to weaken or divide Turkey is often called the “Sèvres syndrome.” Its influence on policy is a matter of analysis, but the treaty’s replacement by Lausanne remains a defining event in modern Turkish history.

Ottoman history also figures in present-day debates over Turkey’s regional role. President Recep Tayyip Erdoğan has drawn on imperial and religious imagery, while Turkey’s foreign policy has combined elements of Ottoman memory, Turkish nationalism and republican practice. These uses of the past do not restore the former empire. Its lasting significance lies in the institutions it created, the communities it governed, the atrocities committed in its final years and the borders and political movements that emerged from its defeat.
