After the overthrow of its Hashemite monarchy in 1958, Iraq became the Arab state most supportive of the UAR. Iraq sought to join the union; however, in 1959 Qasim cancelled the unity talks. After Qasim's overthrow in 1963 the union idea resurrected with the proposal of Egypt, Iraq, and Syria reforming the UAR. A new flag was proposed, with three stars symbolizing the three states constituting the proposed union. However, the plan for a tri-partite union never materialised. Iraq continued to use the three-star flag and later adopted it as the national flag. This three-star flag remained Iraq's national flag (with some modifications) until 2007.
