In the middle of the universe, the small country which illuminates enclosing in red and green color named Bangladesh. It is enclosed in red because of the blood of the martyred freedom fighters who sacrificed themselves and Bangladesh forms only due to their self-abnegation. And it is enclosed in green for the green environment and nature of it. About more than 16 crores people live in this country and it is the motherland of them. It is also an over populated country. But the most important factor for us is that in the page of story, it is known as an independent country. It is not easy to gain independence for a country. Independence can be achieved only after innumerable relinquishment. In the case of Bangladesh, the same thing happened. It was occurred when Bangladesh was not separated. At that time, Pakistan was divided into two parts. One was "East Pakistan" and another was "West Pakistan". Bangladesh was known as "EastPakistan". The west Pakistanis then wanted to establish Urdu as mother tongue but the Bengali did not let them do it. In 1952, the struggle began first by the language agitation. Many students of our country who protested against the west Pakistanis and Urdu language from being our mother tongue. Unfortunately, the students got killed by police and they were Salam, Jabbar, Rafiq, Shafiq and many persons. In 1969, the mass upheaval took place in our country according to the same subject of 1952. and the last battle was happened in 1971. it was our liberation war by which we got our independence. The east Pakistanis that is the Bengali fought the battle against the west Pakistanis to make our country free. For this reason, most people of our country had to pay the cost of gaining independence by sacrificing their lives. The battle continued for nine months. In this nine months, the west Pakistanis did very oppression on the Bengali. They killed so many people about more than 30 lacs and rapped about 2 lacs women. Among them, many advisers, soldiers, poor people were killed in that war by the west Pakistanis. The Bengali endured a lot of things. After so many hardship, lastly Bangladesh become an independent country. It is the noble deed of our freedom fighters that we now live in an independent country. I salute and pray for them from my heart for their blessed duties that they gave us an independent and beautiful country like Bangladesh.
