Ottoman Middle East After WWI: Mandates, New States & Lasting Conflict

The Ottoman Empire's 1918 collapse and 1922 formal dissolution triggered a geopolitical redesign of the Middle East by Britain and France under League of Nations mandates.

Territorial Outcomes

• Turkey: Turkish War of Independence (1919–23) → Republic of Turkey (1923) retaining Anatolia + Eastern Thrace (Treaty of Lausanne).
• French Mandate (Levant): Syria & Lebanon → independent 1946.
• British Mandate (Mesopotamia): → Kingdom of Iraq (1932 independence) under Hashemite monarchy.
• British Mandate (Palestine): Included Transjordan (separated 1921) → Jordan (1946 independence). West Palestine → Israel (1948) + ongoing Palestinian displacement/conflict.
• Hejaz (Arabia): Hashemite Kingdom → conquered by Saudis → Saudi Arabia (1932).

Structural Legacies

• Artificial borders (Sykes-Picot) ignored sectarian/tribal lines → chronic instability.
• Minority rule (Alawites in Syria, Sunnis in Iraq) seeded future conflict.
• Kurdish statelessness across Turkey, Syria, Iraq, Iran.
• Palestine/Israel core unresolved dispute.

The mandate system was colonialism rebranded. Its borders, institutions, and unresolved national questions still define the region's wars and diplomacy a century later.
