As a result of the ongoing Syrian Civil War, there are currently at least two flags used to represent Syria, used by different factions in the war. The incumbent government of the Syrian Arab Republic led by the Ba'ath Party uses the red-white-black tricolour originally used by the United Arab Republic, while Syrian opposition factions such as the Syrian National Coalition use the green-white-black tricolour known as the ''Independence flag'', first used by Mandatory Syria.
