India earned its independence from the British on the 15/8/47. But the British army left India ultimately in 1950. The Indians celebrate 26/1/1950 as the Republic Day of India. On this day the Indian constitution was adopted. Until its independence in 1947, other countries which neighbor India today; Pakistan, Bangladesh (formerly East Pakistan), Myanmar (formerly Burma) and distant places like Aden in present day Yemen; were all parts of British India and were all considered as India. Until then (including the British era) India was never one single country but a collection of kingdoms and authorities with no sense of unity. In this sense India as one single country is mainly a result of British rule. Before that the word India was not used to indicate the present day India, but any kingdom, culture or community that existed between present day Afganistan, in the west, up to China and Myanmar in the east.
