20th century

In 1918, as World War I was ending, the Royal Air Force built an airfield for two planes, and in November the Ottomans retreated from Zor Sanjak without a fight. The Syrian Emirate 's army entered Deir ez-Zor on 4 December, and Zor Sanjak became part of Syria. In 1919, as the British and French argued over the borders of the planned mandates, the British permanent military representative to the Supreme War Council Henry Wilson suggested adding Palmyra to the British mandate. However, the British general Edmund Allenby persuaded his government to abandon this plan. Syria (including Palmyra) became part of the French Mandate after Syria's defeat in the Battle of Maysalun on 24 July 1920.

With Palmyra gaining importance in the French efforts to pacify the Syrian Desert, a base was constructed in the village near the Temple of Bel in 1921. In 1929, Henri Seyrig, began excavating the ruins and convinced the villagers to move to a new, French-built village next to the site. The relocation was completed in 1932; ancient Palmyra was ready for excavation as its villagers settled into the new village of Tadmur. During World War II, the Mandate came under the authority of Vichy France, who gave permission to Nazi Germany to use the airfield at Palmyra; forces of Free France, backed by British forces, invaded Syria in June 1941, and on 3 July 1941, the British took control over the city in the aftermath of a battle.
