The nation is observing the historic March 7 on Tuesday in a befitting manner, commemorating the landmark speech of Father of the Nation Bangabandhu Sheikh Mujibur Rahman, which was touted as an indirect declaration of the country's independence in 1971.

On March 7 in 1971, the great leader Sheikh Mujib, the architect of independent Bangladesh, in his historic address at a mammoth rally at the then Race Course (now Suhrawardy Udyan), directed the freedom-loving Bangalees for waging a decisive struggle against the then Pakistan occupation forces, reports BSS.

"Turn every house into a fortress, resist the enemy with everything you have Having mastered the lesson of sacrifice, we shall give more blood. God willing [Inshallah], we shall free the people of this land," Bangabandhu also said in his speech.

The speech inspired the Bengalees to prepare for a war of independence.

The Liberation War began 18 days later when the Pakistan Army launched "Operation Searchlight" against unarmed Bangalee civilians, intellectuals, students, politicians, and armed personnel on the night of 25 March 1971.

On October 30 in 2017, UNESCO recognised the historic speech as part of the world's documentary heritage as the landmark fiery speech of Bangabandhu inspired the Bengalees to prepare for the War of Liberation in 1971.

It has been included in the Memory of the World International Register, a list of the world's important documentary heritage maintained by the United Nations Educational, Scientific and Cultural Organization (UNESCO.

In the 19-minute extempore speech from 4:23 pm before millions of people of former East Pakistan, Bangabandhu in unequivocal terms said, "We spilled our blood we are ready to shed more blood, the people of the country shall be freed, Inshallah!"

"Ebarer sangram amader muktir sangram, ebarer sangram swadhinatar sangram [The struggle this time is a struggle for emancipation, the struggle this time is a struggle for independence]", Bangabandhu declared in a thunderous voice at the rally.

During his deliberations amid thunderous slogans and applause, he also made a fervent appeal to the roaring people from all walks of life to make preparations for armed struggle against the tyranny, exploitation, subjugation and deprivation by the Pakistani military junta with whatever they possessed and transformed every house into a fortress.

The people were overwhelmed and imbued with the spirit of Bangabandhu's unparalleled speech of independence regarded only as comparable with the Gettysburg Speech of slain US President Abraham Lincoln.

The whole nation responded spontaneously to Bangabandhu's call with the thunderous slogan- "Bir Bangalee Astra Dharo, Bangladesh Swadhin Karo" -Brave Bangalees take up arms and free Bangladesh from occupation.

 The vigorous speech inspired people from all walks of life to prepare for the war, which eventually began after the Pakistani regime on the black night of March 25 launched attacks on the unarmed Bangalees, the worst genocides in history for the next nine months.

Bangabandhu's March 7 speech has been selected as one of the most rousing and inspirational wartime speeches in the last 2,500 years. The dynamic speech has changed the course of the country's history.

The tantalizing speech literally had a mesmerizing and sparkling effect on the entire population of this soil and they became united under his capable and farsighted leadership to bravely fight for liberating the motherland from the clutches of the Pakistani occupation forces.

Although people from all walks of life irrespective of political and religious beliefs were united for the cause and began to take all-out preparations for a bloody war, they waited till the crackdown of the Pakistani occupation forces on the sleeping Bangalees on the night of March 25, defamed as the "Operation Searchlight".

As soon as the Pakistani occupation forces started genocide, Bangabandhu declared the independence of the motherland instructing the people to put up strong resistance and fight against them till liberation is achieved.

At the instruction of Bangabandhu, the brave nation fought successfully during the nine-month-old war of liberation and ultimately liberated Bangladesh from the clutches of the Pakistani occupation forces on December 16, 1971, with the assistance of the allied Indian forces.
