Monarchy of Monaco
reigning monarch and head of state of the Principality of Monaco
The sovereign prince of Monaco (French: prince de Monaco; Monégasque: príncipe de Mónaco) is the monarch and head of state of the Principality of Monaco. All reigning princes and princesses have taken the name of the House of Grimaldi. When Prince Rainier III died in 2005, he was Europe's longest reigning monarch. The Grimaldi family, which has ruled Monaco for eight centuries, is Europe's longest-ruling royal family.
The reigning prince is Albert II, who ascended in April 2005.
Powers of the prince
Monaco, along with Liechtenstein and Vatican City, is one of only three states in Western Europe where the monarch still plays an active role in day-to-day politics.
The Prince of Monaco exercises his authority in accordance with the Constitution and laws. He represents the principality in foreign relations, and any revision, either total or partial, of the Constitution must be jointly agreed to by the monarch and the National Council.
Legislative power is divided between the Prince who initiates the laws, and the National Council which votes on them. Executive power is retained by the monarch, who has veto power over all legislation proposed by the National Council.

Why this record matters
The phrase “reigning monarch and head of state of the Principality of Monaco” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q2457774. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2005.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
