There is a big question mark that why was publically decision of Pakistan making taken on March 1940, why not early? When we study Pakistan movement histroy it is taught from Muslim League creation in 1906 or the mention of War of Idepence of 1857 is also added. Here we will try to analyse.
Though there existed independence struggle in different corners of India from beginning of 19th century but it was unpopular among people and only present in few political circles thus unnoticable. Britsh Goverment was manging to crush such movements quite efficiently and overall innocent masses were unaware of their political rights and were spending their lives under British rule espcially after War of Idepence of 1857 because so many muslims with important independence leaders lost their lives. And their alternatives and British faithfuls were given lot of land and made sit on the places of Martyred War Heroes. Thus whole situation was well controlled by British Rule.
Except when the most prominant incident of Jallianwala Bagh Massacre happened on 13 April 1919.
A large peaceful crowd had gathered at the Jallianwala Bagh in Amritsar, Punjab to protest against the arrest some of Indian independence leaders. In response to the public gathering in the leaders favour Under newly established draconian Law namely Rowlett Act 1919, the British Brigadier Dyer surrounded the Bagh with British army units. The Jallianwala Bagh could only be exited on one side, as its other three sides were enclosed by buildings. After blocking the exit with his troops, he ordered them to shoot at the crowd, continuing to fire even as the protestors tried to flee. The troops kept on firing until their ammunition was exhausted. Estimates of those killed 1500+ people and over 1,200 other people were injured of whom 192 were seriously injured.
Though political leaders were very active for the rights of people expecially All India Cogress and they very well had the plans for independence but people didnt rose enough to lanunch a full fledge effort for indepence All India Muslim League was no where on the front. And it would be very just to say Muslims through different platforms or political parties were fuly active and were equally participating in policitcal activities.
After the incident of Jallianwala Bagh in Amritsar, Punjab there rose the great unrest all across the Indian states and provinces. Political parties especially All India Congress brought people out for protests and made their minds for independence. Here Muslim League so far was not active enough to bring Musims seperately out for their separate Independence. Actually Muslim League till this time wasnt popular among the people.
On the other hand British Rule got upset with the latest unrest amoung people and their country-wide protests maily organised by Congress. On the other at top level Brotshers sent Simon Comission to diffuse the situation. Gandhi gave 4 point report in the favour of simple majority which goes in favour of Hindus whereas Quaid-e-Azam gave 14 points to protect all religious groups of India to protect Muslims from Hindu dominance.
Though Muslim League did not have roots in masses, still they were given participation to sit in round-table conferences by British Raj. Laterly as the result of the Simon Comission Repot an act namely Government Of India Act 1935 as which all parties rejected but next Electiions 1937 were held under this Act. And being unpopular Muslim League couldnt win any seat and All India Congress managed to win the elections with vast majority. Even for Muslim seats, Muslims trusted candidates who contested under the flag of All India Congress, means Muslims didnt so far had enough trust over Muslim League because they didnt motivated Muslims for political struggle. It was All India Congress who worked on masses which worked for all and sundry of India. It also suggests that till 1937 common Muslims didnt want separate homeland for Muslims and they were together with Hindus for freedom struggle.
After the formation of Government by Congress all the ministries were given to Hindus. Here they turned their eyes against Mulims and they casted heavy inflictions upon Muslims. Here after witnessing brutalities of Congress Hindu Ministeris Muslims first time felt their mistake and stood against Hindu majority Congress. As a result and their poor performance Government was dissolved in 1939. Muslims celebrated thanks giving day.
Here first time Muslims in vast majority turned towards All India Muslim League. And due to this reason Resolution For Independent Pakistan was first time passed in 1940. From now on Muslims struggled under this resolution and Mulsim League Flag and won their freedom. As a result we are breathing in the independet horizon of our beloved Pakistan. Among Muslims whoever could won the freedom from Hindus are still daily tortured, lynched and even badly martyred like in Kashmir or in Modi Party majorty areas of India.
