Sri Lanka Flag:
The Sri Lanka flag was officially adopted on December 17, 1978.
Prior to 1815, the gold lion was originally the national flag of Ceylon; its four pipul leaves are Buddhist symbols and the sword is said to represent authority. On this modern version, the green represents Muslims, while the orange represents Hindus.
