Introduction

The national flag of Bangladesh is a simple yet powerful design featuring a vibrant red disc offset on a field of bottle green. This distinctive flag is one of the few national flags to feature a single, off-center emblem on a plain background, creating a bold and instantly recognizable visual identity. The flag's proportions and the precise placement of the disc are strictly defined by law, ensuring its consistent representation.

Adopted shortly after the nation's independence, the flag's colors and symbolism are deeply tied to the Bangladesh Liberation War of 1971. The design deliberately avoids complex imagery or text, relying on the stark contrast between the two colors to convey its message. The red sun represents the blood shed for freedom, while the green field symbolizes the lush landscape of the country.

Meaning & Symbolism

The bottle green field of the flag represents the lushness of the land, the vitality of youth, and the agricultural abundance of Bangladesh. It is a direct homage to the country's verdant landscape and its reliance on the land. The vibrant red disc is a multifaceted symbol, representing both the rising sun of independence over Bengal and the blood sacrificed by martyrs during the liberation struggle.

The disc's position, slightly offset toward the hoist, ensures it appears centered when the flag is flying. This practical design choice also carries symbolic weight, as the sun is seen as eternally rising on the nation. The flag's overall simplicity allows these two core elements—land and sacrifice—to stand without distraction, making its meaning clear and potent.

History of the Bangladesh Flag

The flag was first hoisted at the University of Dhaka on March 2, 1971, by student leaders and later officially adopted by the provisional government on January 17, 1972. The original design, used during the liberation war, featured a golden map of Bangladesh inside the red disc, which was later removed to simplify the design. The creator of the initial flag is widely accepted to be Quamrul Hassan, a renowned painter.

The design was finalized under the guidance of the first Prime Minister, Sheikh Mujibur Rahman. The original flag, with the map, is preserved in the Liberation War Museum in Dhaka. The current, simplified version has remained unchanged since its official adoption, becoming a steadfast national symbol.

Construction Sheet

The flag's construction is precisely governed by law. The length to width ratio is 10:6. The red disc has a radius equal to one-fifth of the flag's length. Its center is placed on the intersecting point of the vertical middle line and a horizontal line drawn nine-twentieths (9/20) of the flag's length from the top. This precise offset ensures the disc appears centered when the flag is flying on a pole.
