Later, the Netherlands was defeated in the British campaign, and the East India Company became a British company, which also became the management organization of British colonization in India. Britain began a century-long colonial aggression and resource occupation. Later, when Britain and China engaged in opium trade, that is,19th century, the Indian people began to unite with various small vassal states to hold the I-century uprising, and finally founded the country in the late 20th century.
