Today, there are over 500 million Muslims throughout the Indian subcontinent (India, Pakistan, and Bangladesh), making it one of the largest population centers of Muslims in the world. Since Islam first entered India, it has contributed greatly to the area and its people. Today, numerous theories about how India came to be such a largely Muslim land exist. Politically, some (such as the Hindutva movement in India) try to make Islam seem foreign to India, by insisting it only exists because of invasions by Arab and Persian Muslims. The truth, however, is far from that.
He encountered little resistance as he made his way into India. When he reached the city of Nerun, on the banks of the Indus River, he was welcomed into the city by the Buddhist monks that controlled it. Most cities along the Indus thus voluntarily came under Muslim control, with no fighting. In some cases, oppressed Buddhist minorities reached out to the Muslim armies for protection against Hindu governors.
Despite the support and approval of much of the population, the Raja of Sindh, Dahir, opposed the Muslim expansion and mobilized his army against Muhammad bin Qasim. In 712, the two armies met, with a decisive victory for the Muslims. With the victory, all of Sindh came under Muslim control.
It is important to note, however, that the population of Sindh was not forced to convert to Islam at all. In fact, for almost everyone, there was no change in day-to-day life. Muhammad bin Qasim promised security and religious freedom to all Hindus and Buddhists under his control. For example, the Brahman caste continued their jobs as tax collectors and Buddhists monks continued to maintain their monastaries. Due to his religious tolerance and justice, many cities regularly greeted him and his armies with people dancing and music.
Because pre-Islamic India was entirely based on a caste system in which society was broken into separate parts, conversion to Islam happened in a step-by-step process. Often, entire castes would convert to Islam at a time. This would happen for many different reasons. Often, however, the equality Islam provided was more attractive than the caste system's organized racism. In the caste system, who you are born to determines your position in society. There was no opportunity for social mobility or to achieve greater than what your parents achieved. By converting to Islam, people had the opportunity to move up in society, and no longer were subservient to the Brahman caste.
Buddhism, which was once very popular in the subcontinent, slowly died out under Muslim rule. Traditionally, when people wanted to escape the caste system, they would move to the major population centers and convert to Buddhism. When Islam became an option, however, people began to convert to Islam instead of Buddhism, while still leaving the caste system. The myths of Islam violently destroying Buddhism in India are simply false. Buddhists were tolerated under Muslim rule and no evidence exists that shows forced conversions or violence against them.
Wandering teachers also had a major role in bringing Islam to the masses. Muslim scholars traveled throughout India, making it their goal to educate people about Islam. Many of them preached Sufi ideas, a more mystical approach to Islam that appealed to the people. These teachers had a major role in bringing Islam to the masses in the countryside, not just the upper classes around the Muslim rulers.
If Islam spread through violence and warfare, the Muslim community today in India would exist only in the areas closest to the rest of the Muslim world. Thus only the western part of the subcontinent would have any Muslim population at all. What we see instead is pockets of Islam throughout the subcontinent. For example, Bangladesh and its 150 million Muslims are in the far east, separated from other Muslim-majority areas by Hindu lands in India. Isolated communities of Muslims also exist in western Myanmar, central India, and eastern Sri Lanka. These communities of Muslims are proof of Islam spreading peacefully throughout India, regardless of whether or not a Muslim government existed there. If Islam spread by force as some claim, these communities of Muslims would not exist.
