The short answer:
Independence often brings a new national flag. A new design can signal sovereignty and create a visible break from colonial rule.
Independence often brings a new national flag. A new design can signal sovereignty and create a visible break from colonial rule.
A symbol of a new beginning
A newly independent state needs symbols that represent its own sovereignty. A national flag can be one of the most immediate and visible expressions of that independence.
Colours from local history
New flags often use colours and symbols connected with local political movements, landscapes, cultures or pre-colonial history.
Keeping parts of the past
Independence does not always mean abandoning every older symbol. Some countries retain colours or design elements that existed before independence.
Flags can evolve again
A country may change its flag more than once after independence as governments change or national ideas develop.
