Title: Constitution of India
Content:  The constitution was drawn from a number of sources. Mindful of India's needs and conditions, its framers borrowed features of previous legislation such as the Government of India Act 1858, the Indian Councils Acts of 1861, 1892 and 1909, the Government of India Acts 1919 and 1935, and the Indian Independence Act 1947. The latter, which led to the creation of India and Pakistan, divided the former Constituent Assembly in two. The Amendment act of 1935 is also a very important step for making the constitution for two new born countries. Each new assembly had sovereign power to draft and enact a new constitution for the separate states.
