- The US Constitution was the first to begin with a Preamble. - The phrase "We, the people..." in the Indian Preamble is directly borrowed from the US Constitution's Preamble. - While the ideals mentioned in the Preamble draw from various sources (e.g., Liberty, Equality, Fraternity from the French Revolution), the structural idea of having a Preamble as the introductory part of the constitution defining its objectives and guiding principles comes from the USA.
