Ottoman Empire: Decline, European Intervention, and Geopolitical Shifts (18th-20th Centuries)
This study material synthesizes information from a lecture audio transcript and a copy-pasted text, providing a comprehensive overview of the Ottoman Empire's decline and its interactions with European powers from the late 18th to the early 20th century.
1. Introduction: The Dawn of Decline 📉
Following the Treaty of Küçük Kaynarca in 1774, the Ottoman Empire's long-standing military superiority over Europe began to wane. European powers, recognizing this weakening, intensified their efforts to partition Ottoman territories. This period marked a significant shift from Ottoman expansion to a struggle for survival, characterized by internal reforms and a complex foreign policy.
2. European Ambitions and Projects on Ottoman Lands 🌍
European states, driven by their own geopolitical interests, devised various strategies to dismantle the Ottoman Empire:
-
📚 The Greek Project (Grek Projesi):
- Conceived by: Russia's Catherine II and Austria's Joseph II.
- Aim: To expel the Ottomans entirely from Europe and revive the Byzantine Empire.
- Outcome: This ambitious project ultimately failed to materialize due to the death of Joseph II.
-
📚 The Eastern Question (Şark Meselesi):
- Definition: A long-standing diplomatic and political problem concerning the future of the Ottoman Empire, particularly its European territories, and the balance of power in Europe.
- Phases:
- Phase 1 (1071-1683): European states primarily focused on stopping Turkish expansion (e.g., Crusades). They were largely on the defensive.
- Phase 2 (Post-1683, especially after Vienna Siege): European powers shifted to an offensive stance, actively seeking to expel Turks from Europe and partition Ottoman lands. They exerted political and economic pressure, often using non-Muslim minorities as a pretext to interfere in Ottoman internal affairs and incite nationalist uprisings.
3. Internal Challenges and Ottoman Responses 🛡️
The Ottoman Empire faced significant internal pressures, exacerbated by external influences:
- Impact of the French Revolution (1789):
- Spread of ideas like nationalism, liberty, and national will across Europe.
- These ideas challenged monarchical rule and fueled nationalist movements within the multi-ethnic Ottoman Empire, leading to revolts by various minority groups.
- Vienna Congress (1815) & Metternich System:
- Purpose: European powers convened after the Napoleonic Wars to restore the old monarchical order and suppress revolutionary ideas.
- Metternich System: Advocated for mutual assistance among monarchs to prevent nationalist and liberal movements. This system aimed to maintain the status quo against the principles of the French Revolution.
- Ottoman Reforms:
- Recognizing its decline, the Ottoman Empire initiated reforms to modernize and address internal issues.
- Abolition of Janissaries: During the reign of Mahmud II, the Janissary Corps, which had become a source of internal instability, was abolished to establish a modern army.
- Tanzimat and Islahat Edicts: These reform decrees aimed to grant more rights and privileges to minorities, hoping to appease them and prevent nationalist uprisings.
- 💡 Balance of Power Policy (Denge Politikası):
- As the Empire weakened, it adopted a foreign policy of aligning with different European powers to counter threats from others.
- Example: During Napoleon's invasion of Egypt (1798), the Ottomans sought help from European powers. Later, they would align with Britain and France against Russia, or with Russia against other powers, to protect their interests. This policy was first used during the French occupation of Egypt.
4. Key Conflicts and Diplomatic Outcomes ⚔️
The 19th century was marked by a series of wars and treaties that progressively eroded Ottoman sovereignty:
-
Mora Rebellion and Greek Independence (1821-1829):
- Causes: Nationalist sentiments fueled by the French Revolution, European instigation, and local revolts (e.g., Tepedelenli Ali Pasha's rebellion).
- Ottoman Response: The Ottoman Empire, unable to suppress the rebellion alone, sought assistance from Mehmet Ali Pasha of Egypt.
- European Intervention: Britain, France, and Russia intervened, culminating in the destruction of the Ottoman fleet at Navarino.
- ✅ Treaty of Edirne (1829): Officially recognized Greek independence, marking the first successful nationalist secession from the Ottoman Empire.
-
Crimean War (1853-1856):
- Causes: Russia's persistent ambition to gain access to warm seas (Mediterranean) via the Ottoman Straits, and disputes over the protection of Holy Places in Palestine.
- Alliances: The Ottoman Empire, supported by Britain, France, and Piedmont (Italy), fought against Russia.
- Outcome: The allies defeated Russia.
- ✅ Treaty of Paris (1856):
- The Ottoman Empire was formally recognized as a European power and its territorial integrity was guaranteed.
- However, this also allowed for increased European interference under the pretext of overseeing Ottoman reforms (e.g., Islahat Fermanı).
- The Black Sea was neutralized, prohibiting warships of both Russia and the Ottoman Empire.
- ⚠️ This treaty, despite being a victory, highlighted Ottoman weakness as it needed European guarantees for its existence.
-
Russo-Turkish War (1877-1878) / 93 War:
- Causes: Russian expansionism, Pan-Slavism (uniting Slavic peoples under Russian leadership), desire for revenge for the Crimean War, and Balkan uprisings.
- Ottoman Defense: Notable resistance from commanders like Gazi Osman Pasha (Plevna) and Ahmet Muhtar Pasha (Caucasus).
- Treaty of San Stefano (1878): A highly pro-Russian treaty that significantly increased Russian influence in the Balkans.
- European Reaction: Other European powers, concerned about the shift in the balance of power, rejected San Stefano.
- ✅ Congress of Berlin (1878):
- Key Outcomes: Significant territorial losses for the Ottomans.
- Kars, Ardahan, and Batum were ceded to Russia.
- Serbia, Romania, and Montenegro gained full independence.
- Bulgaria's borders were reduced, and it was divided into three parts.
- Bosnia-Herzegovina was placed under Austrian administration.
- Cyprus was temporarily ceded to Britain.
- ⚠️ Article 61: Mandated reforms for Armenian-populated areas, laying the groundwork for the "Armenian Question" and future European interference.
5. The Straits Question 🌊
The control and passage through the Bosphorus and Dardanelles Straits became a persistent international issue:
- Origin (1774): The Treaty of Küçük Kaynarca granted Russia commercial navigation rights in the Black Sea and through the Straits, effectively ending the Black Sea's status as a "Turkish lake."
- Evolution:
- 1798: Russian warships passed through the Straits for the first time during Napoleon's invasion of Egypt.
- 1809 (Çanakkale/Kala-i Sultaniye Treaty): Britain agreed to close the Straits to warships during peacetime.
- 1833 (Hünkar İskelesi Treaty): Following Mehmet Ali Pasha's rebellion, the Ottomans allied with Russia, granting Russia exclusive rights to close the Straits to non-Russian warships if Russia was at war. This was the last time the Ottoman Empire made a unilateral decision regarding the Straits.
- ✅ 1841 (London Straits Convention): Internationalized the Straits, ending full Ottoman sovereignty over them. It stipulated that the Straits would be closed to all foreign warships during peacetime.
6. Balkan Wars (1912-1913) 🇧🇬🇬🇷🇷🇸🇲🇪
These wars marked the final stage of Ottoman territorial loss in Europe before WWI:
- First Balkan War:
- Combatants: A coalition of Bulgaria, Greece, Serbia, and Montenegro attacked the Ottoman Empire.
- Causes: Nationalist aspirations, Ottoman weakness (especially after the Italo-Turkish War in Libya), and desire for territorial gains.
- Outcome: Devastating defeat for the Ottomans, losing most of their remaining European territories, including much of Thrace.
- ✅ Treaty of London (1913): Formalized these territorial losses.
- Second Balkan War:
- Causes: Disputes among the victorious Balkan states over the division of spoils from the First Balkan War. Bulgaria, having gained the most, was attacked by its former allies (Serbia, Greece, Montenegro) and Romania.
- Ottoman Gain: The Ottoman Empire capitalized on this disunity to reclaim Eastern Thrace, including Edirne.
- Reasons for Ottoman Defeat:
- Ordunun siyasete karışması (Army's involvement in politics).
- Lack of discipline and preparedness.
- Premature demobilization of experienced soldiers before the war.
7. Ottoman Alliance Search Before World War I 🤝
Leading up to WWI, the Ottoman Empire actively sought alliances to secure its future:
- Reasons for Seeking Alliance:
- To recover lost territories.
- To escape political isolation in a rapidly polarizing Europe.
- Rejection by Entente Powers (Britain, France, Russia):
- They perceived the Ottoman Empire as too weak and a liability.
- They already had existing plans for the partition of Ottoman territories.
- Alliance with Central Powers (Germany):
- German Motives:
- To open new fronts and divert Allied forces, especially Russia.
- To leverage the Ottoman Caliphate's religious authority (Jihad) over Muslims in Allied colonial empires.
- To utilize the Ottoman Empire's significant manpower.
- To exploit its crucial geopolitical location, particularly control over the Straits.
- Outcome: The Ottoman Empire joined the Central Powers alongside Germany, marking its entry into World War I.
- German Motives:
Conclusion: A Century of Struggle 📜
The period from the late 18th to the early 20th century was a profound era of decline for the Ottoman Empire. Faced with relentless European expansionism, the rise of nationalism, and internal weaknesses, the Empire struggled to maintain its territorial integrity. Its attempts at modernization and diplomatic maneuvering through the "Balance of Power" policy provided temporary reprieves but ultimately could not prevent significant territorial losses and increasing foreign interference. These events progressively eroded Ottoman sovereignty and set the stage for its eventual entry into World War I, marking the final chapter of its long and complex history.
