in India as Republic Day. Previous legislation 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. Constituent Assembly The constitution was drafted by the Constituent Assembly, which was elected by elected members of the provincial assemblies. The 389-member assembly (reduced to 299 after the partition of India) took almost three years to draft the constitution holding eleven sessions over a 165-day period. Having studied the constitutions of about 60 countries, Ambedkar was considered a wise constitutional expert. Ambedkar is recognised as the "Father of the Constitution of India".
