The opening phrase "we the people of the federal republic of Nigeria" is usually found in the preamble of the Nigerian Constitution. The preamble is an introductory statement that sets forth the purpose and guiding principles of the constitution. It outlines the aspirations and objectives of the Nigerian people as a sovereign entity, and serves as a reminder that the Constitution is an instrument created by and for the people. The preamble is an important part of the constitution, as it sets the tone for the entire document and provides a framework for the interpretation of its provisions.
