The Fall of the Ottoman Empire and the Remaking of West Asia

For centuries the Ottoman Empire ruled much of West Asia and North Africa. In the First World War it backed the losing side. The empire did not survive the peace.

Its fall redrew the map of the region. It also left behind a set of promises that did not match one another. This lesson follows those deals, the new Turkey that rose from the wreckage, and why the effects still show today.

1How did the Ottoman Empire collapse?

The Ottomans entered the war on the side of Germany and Austria-Hungary. They lost. An armistice, signed at Mudros on 30 October 1918, ended the fighting in the Middle East.

Allied forces then occupied key places. The empire’s lands were open to being carved up. Out of the chaos came a Turkish nationalist movement led by Mustafa Kemal.

Why does this matter? The empire’s end was not a single day. It unfolded over several years, from defeat to a new republic.

• Armistice of Mudros: 30 October 1918.
• Ottomans were on the losing side with Germany.
• Turkish nationalists rose under Mustafa Kemal.

2What were the wartime deals?

During the war, Britain made three different commitments. They were not meant to fit together.

First came promises to the Arabs. Britain backed an Arab Revolt against the Ottomans, which began at Mecca on 10 June 1916. The rebels hoped for an independent Arab state.

Second came a secret deal with France. The Sykes-Picot Agreement of 1916 divided Ottoman lands into British and French zones. Russia and Italy gave their assent.

Third came the Balfour Declaration of 2 November 1917. Britain announced support for a “national home for the Jewish people” in Palestine, then an Ottoman region.

Why does this matter? Many writers see these promises as clashing with each other. Exams ask you to keep them apart.

• Arab Revolt, June 1916: promise of independence.
• Sykes-Picot, 1916: secret Britain-France division.
• Balfour Declaration, 1917: Jewish national home in Palestine.

3What were mandates?

After the war the League of Nations set up the mandate system. It covered lands taken from the defeated powers. A Western power ran each one on the League’s behalf.

Britain and France took charge of the former Ottoman Arab lands this way. Britain held the Mandate for Palestine. France held the Mandate for Syria and Lebanon.

A mandate was a different legal status from a colony. Yet in practice, control often felt much the same to the people who lived there.

Why does this matter? Many borders in the region were drawn in this period. They often ignored local ethnic and religious ties.

• Mandates: a League of Nations status, not a colony.
• Britain: Palestine. France: Syria and Lebanon.
• Borders often ignored local ties.

4Why did Sevres fail and Lausanne last?

The Treaty of Sevres was signed on 10 August 1920. It would have handed large Ottoman lands to France, Britain, Greece and Italy. It also set up big Allied occupation zones.

Turkish nationalists refused to accept it. The treaty was never ratified. It was replaced by a second attempt at peace.

That attempt was the Treaty of Lausanne, signed on 24 July 1923. It settled the conflict and recognised the new Turkish state.

Why does this matter? Sevres is the harsh treaty that failed. Lausanne is the one that stuck.

• Sevres, 10 August 1920: never ratified.
• Lausanne, 24 July 1923: the lasting treaty.

5How did Ataturk build a secular republic?

The Grand National Assembly in Ankara abolished the sultanate on 1 November 1922. The last sultan, Mehmed VI, left Constantinople later that month.

The Republic of Turkey was proclaimed on 29 October 1923. Mustafa Kemal became its leader, later known as Ataturk.

On 3 March 1924 the caliphate was abolished too. This was a separate step, taken about four months after the republic began. It ended the last link with the old monarchy.

Why does this matter? Many students merge the sultanate and the caliphate. They were two institutions, ended in two different years.

• Sultanate abolished 1 November 1922.
• Republic proclaimed 29 October 1923.
• Caliphate abolished 3 March 1924.

6Why did India care about the Caliphate?

Muslims in British India watched the fate of the Ottoman Empire closely. The Sultan was also seen as Caliph. News of the planned break-up angered many of them.

This led to the Khilafat movement, from 1919 to 1922. Gandhi backed it. He linked it to the wider Non-Cooperation Movement. It became a sign of Hindu-Muslim unity.

Why does this matter? The fall of the Ottomans was not only a West Asian story. It shaped politics in India too.

• Khilafat movement: 1919-1922.
• Backed by Gandhi, linked to Non-Cooperation.

7Why does the post-Ottoman map still matter?

Many present-day disputes in West Asia trace back to this period. Borders were drawn by outside powers. Local ethnic and religious ties were often ignored.

The Kurds are one example. They live across several modern states, and they have no state of their own. The Palestine question is another.

Why does this matter? When a question asks for the roots of a modern dispute, this settlement is often the answer.

• Borders drawn by outside powers.
• Kurds split across several states.
• Modern disputes have post-Ottoman roots.

8What are the exam traps?

• Sykes-Picot (1916), Balfour (1917) and the Arab Revolt promises are three separate things.
• A mandate is not a colony in law.
• Sultanate (1922) and caliphate (1924) were abolished separately.
• Sevres (1920) failed. Lausanne (1923) lasted.
