Europe And india
The Europeans ruled the Indian subcontinent between 1858 and 1947. The British first arrived in India due to trade. British rule over India all started with a global trading company called East India Company. This trading company grew vastly until it conquered most of South Asia. When the European ships first arrived they encountered the Munghul Empire which was more powerful than any country in Europe at the time. When the Europeans first came they came in search for trade rather than invasion. Europe had never been politically unified even before Europeans invaded simply due to the various physical barriers throughout the country.
