The National Flag is the most important symbol of a nation’s identity, pride, and unity. It represents the country’s sovereignty, culture, and heritage, reminding every citizen of their duty and love for their motherland. Every nation in the world has its own flag, which carries deep meaning through its colours, design, and symbols. The National Flag of Bangladesh, for example, consists of a red circle on a green background. The green colour represents the lush beauty of the land and the eternal youth of the people, while the red circle symbolises the blood of the martyrs who sacrificed their lives for independence in 1971. It is a reminder of the nation’s struggle, courage, and freedom. The flag is hoisted on government buildings, schools, and offices on national days such as Independence Day and Victory Day, and it is treated with the utmost respect. It is raised in the morning and lowered before sunset, never allowed to touch the ground, as a mark of honour. The national flag unites people from different regions, religions, and cultures under one common symbol of patriotism. It inspires citizens to work together for peace, progress, and prosperity. Every child learns to salute the flag and feel proud of their country from an early age. In essence, the national flag is not just a piece of cloth—it is a living emblem of a nation’s soul, freedom, and everlasting glory.
