Louis I of Monaco
Monegasque prince (1642-1701)
Louis I (25 July 1642 in Prince's Palace of Monaco – 3 January 1701 in Rome) was Prince of Monaco from 1662 until 1701.
Early life
Louis Grimaldi was the elder son of Prince Hercule of Monaco and Genoese noblewoman, Maria Aurelia Spinola. His younger siblings were Maria Ippolita Grimaldi (wife of Carlo Emanuele Filiberto de Simiane, Prince of Montafia), Giovanna Maria Grimaldi (wife of Andrea Imperiali, Prince of Francavilla), and Teresa Maria Grimaldi (wife of Sigismondo III d'Este, Marquis of San Martino).
Reign
In 1662, Louis succeeded his grandfather Honoré II as Prince of Monaco. In 1666 he distinguished himself at the Four Days' Battle between the English and Dutch fleets. On 5 July 1668 he took the oath to King Louis XIV of France in the Parlement on account of being Duke of Valentinois and a Peer of France. He was made a knight of the French royal orders on 31 December 1688.
In 1699, Louis XIV sent Louis to Rome as ambassador extraordinary. There on 19 December he presented the insignia of the Order of the Holy Spirit to James Louis and Alexander Benedict Sobieski, the two sons of King John III of Poland. Louis remained in Rome until his death there in 1701.
This brief starts where responsible research should: with the source description of “Louis I of Monaco” as monegasque prince (1642-1701). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as monegasque prince (1642-1701). Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q878282. VIAF identifies the subject as 5115172337997815650009. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1642, 1701, 1662 and 1666.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
