The flag of Belize was designed after a long political process involving all the stakeholders in the country. In the center of the flag is the Belize coat of arms which was designed in 1907 and based on the badge worn by British soldiers stationed in Belize. A History Of The Belize Flag Why the Belize flag is so unique Not many people are aware of the fact that flag design is one of the most important tasks a nation can undertake. In the end, the unofficial national flag that had been flown by Belize’s People’s United Party earned consensus. As a gesture of gratitude to this volunteer and to the people of Belize, that Belize flag was given to Belize, which is how it came to be on display at the museum.
