Gib,
It would be unfair of me if I ignore the independent struggle and some important personalities involved in it.
All that happened in the first half of 19th century. Basically, there were two forces behind that motion. One was extremist, who believed that any mean which can throw the British out of the India is valid, even if it includes violence. The second way was innovated and adopted by the Gandhi, the peaceful protest and non-cooperation moment.
The extremists were not united in their effort, but still affective. They used to rob British arms and money and sometimes kill them too. Some of those made a blast in the British Assembly in the London too.
But, the Congress was far more organized in its effort. Gandhi became the nucleus of it and the rest moved around him. His concept of peaceful non- cooperation moment was very well accepted by the masses and gave a lot of trouble to the British too. He simply asked people to disengage with the British and all their things, like stop paying taxes, not to sell anything to them, discard all English goods like clothes and other consumer durables etc. He asked Indians to become self-reliant.
He also used the very old Hindu concept of Fasting as Hunger Strike. This motivated people very much and caused trouble to the British. Even within the Congress, there were two streams, Right wingers and liberals. Right wingers were of the opinion of drawing the British to the uncomfortable zone, while liberals want to settle the things via dialogue only.
Gandhi was himself a liberal and very much against any use of violence and his ideology was dominant in Congress. Right wingers were in minority and headed by Bose. Bose was very much against for sending Indian soldiers to fight in the world war under the British army, but Gandhi did not listened to him. As the result, Bose left the Congress and formed his own army of Indian soldiers with the help of Japanese and Hitler and fought with British Army in the North-East front and tasted some success too. But, his untimely death in a plane accident curbed the military option.
Except Gandhi, there were some other prominent leaders in the Congress, who deserve mentioning as they influenced India quite a bit later, namely Nehru, who became the first prime minister of the India, Zinna, who became the first prime minister of the Pakistan, and Patel, who became the first home minister of the India.
Before going for other persons, let me say a few words about Gandhi. He was truly a charismatic leader with a huge mass appeal, which is almost unparallel in the history of India at least, if not the world. People were ready to put even their lives on the stake on his call. He was simple, dedicated and honest. And, always spoke the truth and never used violence, no matter what may be the consequences.
This looks a simple thing but very hard to live by. I do not think that now any one would be able to follow that. He kept himself away from all the glamour and even refused to take any portfolio in administration in independent India. He wore only wooden sandels in his feet and just a self made piece of cloth around his body. The important thing to notice is that, he used to knit yarn himself from the cotton for his needs and also asked other to do the same. He was not in the favor of much industrialization and conceived village as a cornerstone of the governance and economy. His emphasis was to make village a self-sustained body and not dependent on big cities, though his ideology was not much followed later as Nehru adopted industrial development.
There is no doubt that he was the most influential person in the history of modern India, and rightly called the Father of the Nation too, yet, he made some mistakes too. The basic flaw in his character was that he was somewhat egomaniacal in his nature. This is to say that he was not open to review his ideas and perceptions, even if those are not yielding desired results.
Firstly, he opposed even a slight hint of violence in the independence struggle. The British would have been easily succumbed at the time of world wars as they cannot afford any fight here, because all their forces were engaged elsewhere. On the contrary, he offered British the help of Indian soldiers and gave them moral support too. Had he supported the Bose at that time, India would have been independent much earlier and even far bigger demographically too, as is evident from the picture below-

At that time, some neighboring countries like Pakistan, Nepal, Bhutan, Bangladesh and Myanmar were considered a part of British Indian Empire.
Despite the mistake of supporting the British in the world war, Gandhi made one more very serious error that changed the history of the India, and that was his blind favor for Nehru. This was the main reason of the partition of India and Pakistan.
Like Gandhi, Nehru was also very popular with the masses, but was not that noble intent wise. He belonged to a very rich family and his whole education was done in England. He was a very ambitious and egoistic person and had all the habits which an elite could had. But, very carefully, he kept his public image very appealing. The same was the story of the Zinna, the founder of the Pakistan.
The partition of the Erstwhile India into two different countries was really the tussle between Nehru and Zinna. Contrary to the general perception, Zinna was very liberal Muslim, who never went to any mosque in his whole life to offer prayers. Both of them wanted to become the prime minister, but Gandhi favored Nehru. Though, there was a time, when Zinna agreed for Patel as a PM, and himself and Nehru as a vice PMs, but, Gandhi wanted Nehru to be the PM at any cost.
Then, Zinna had no option but to play the religious card and put the theory of two nations forth. The whole of the congress and Gandhi himself were against it, but it created that much of bloodshed that they had no other option but to accept it. Thus, the Pakistan was formed on the religious lines, but India remained secular, and that difference is still very much evident even after 67 years.
