The State of Greater Lebanon (Arabic: دولة لبنان الكبير, romanized: Dawlat Lubnān al-Kabīr; French: État du Grand Liban), informally known as French Lebanon, was a state declared on 1 September 1920, which became the Lebanese Republic (Arabic: الجمهورية اللبنانية, romanized: al-Jumhūriyyah al-Lubnāniyyah; French: République libanaise) in May 1926, and is the predecessor of modern Lebanon.
The state was declared on 1 September 1920, following Decree 318 of 31 August 1920, as a League of Nations Mandate under the proposed terms of the Mandate for Syria and the Lebanon which was to be ratified in 1923. When the Ottoman Empire was formally split up by the Treaty of Sèvres in 1920, it was decided that four of its territories in the Middle East should be League of Nations mandates temporarily governed by the United Kingdom and France on behalf of the League. The British were given Palestine and Iraq, while the French were given a mandate over Syria and Lebanon.
