Colonization by Portuguese
The Portuguese, after establishing their hold on certain pockets in India, began to attack the Arabs who were in India only for trade. They made themselves strong and influential by meddling with the internal affairs of the states and sending Jesuit priests for religious conversions. Thus began the Portuguese colonization.
England, France and the Netherlands got panicky at the monopoly the Portuguese established in their trade with India, and they lost no time to register private trading companies (in the 17th century) and challenged their rival.
New trading companies came up - the British East India Company, East India Company of the Netherlands, French East India Company, Swedish East India Company – the Europeans were getting ready to move to Africa and Asia for their business and political expansions. And the ground was getting ready for India and other countries to be enslaved by the powerful forces from the West.
