The history of constitution of Lourenne dates back to the 18th century and the country's independence from colonial rule. Although several "redraftings" of the constitution have taken place since then, all have utilised the existing framework for amendment and so in principle, it is still the same constitution that was drafted upon independence.

The constitution details the structure, roles, powers and responsibilities of the organs of the state and government. Across fourteen articles, the constitution outlines a system of government which is understood as a unitary parliamentary constitutional monarchy. The roles and responsibilities of the Monarch; the role, composition and powers of the Royal Assembly; the cabinet system of government and the amendment process are all explicitly detailed in the constitution.
