Constitution of San Marino
uncodified constitution of San Marino

The constitution of the Republic of San Marino is distributed over a number of legislative instruments, the most important of which are the Statutes of 1600 and the Declaration of Citizen Rights of 1974, as amended in 2002.
The constitutional system shows influences of Roman customary law and Justinian I's Corpus Juris Civilis (529–534).
It is the world's oldest surviving constitution of any sovereign state, barring England's Magna Carta (1215).
The Statutes of 1600
The current legal system of the San Marino began on 8 October 1600. The government gave binding force to a compilation of Statuti written by Camillo Bonelli, covering the institutions and practices of Sammarinese government and justice at that time. It was written in Latin and contained in six books. The title in Latin is Statuta Decreta ac Ordinamenta Illustris Reipublicae ac Perpetuae Libertatis Terrae Sancti Marini.
The new system was an update on the Statuti Comunali (Town Statute) which had served San Marino from about 1300. Existing institutions, such as the Council of the Sixty, were carried forward from this period. The Statutes form the basis of all law in effect today, and so it may be the oldest constitution of any existing nation.

Why this record matters
The subject matters to the history & society register because the source frames it as uncodified constitution of San Marino. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Dec 28, 2025. The linked authority identifier is Q1143322. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1600, 1974, 2002 and 1215.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
