While the Preamble was adopted on January 22, 1947, based on the Objectives Resolution moved by Jawaharlal Nehru, the actual drafting and presentation of the Objectives Resolution itself, which formed the basis of the Preamble, is attributed to Nehru. The Drafting Committee, headed by Dr. B.R. Ambedkar, later incorporated these principles into the Constitution. However, the initial conceptualization and proposal of the Preamble's spirit came from Nehru's Objectives Resolution.
