The first flag to be used by the Syrians was the current flag of Jordan back in 1920 with the green and white colors reversed. The colors and design were taken from the Pan-Arab flag. The star stood for the fact the Syria was the first country to use the Pan-Arab colors. The French changed the flag of Syria under their mandate into a blue flag with a white circle in the center and a French flag in the canton. After a month the flag was changed into a horizontally striped green-white-green flag and a French flag in the canton. This flag was in use from 1925 until 1936. Then the flag was changed into a horizontally striped green-white-black flag with three red stars in the center of the white stripe. This followed the signing of the Franco-Syrian treaty which gave Syria was added after Sharif Hussayn of Hijaz agreed to join the Arab revolt of 1916.
The first national flag of Syria after independence in 1944 was a green-white-fl horizontal tricolour, with three red five-pointed stars.
In 1958, Syria and Egypt merged to form the United Arab Republic and adopted the red-white-fl design with two green stars that is Syria's current flag.
The colors of the flag are traditional Pan-Arabic colors, also seen on the flags of Yemen, Egypt, Sudan, and Iraq.
