Ramon Rabasa de Perellós y Rocafull[1] (pronounced [raˈmon raˈba.sa pe.ɾeˈʎoz i ɾo.ka.ˈfuʎ]; 1637 in Valencia – 10 January 1720 in Valletta) was a Spanish knight of Aragon who served as the 64th Prince and Grand Master of the Order of Malta from 1697 until his death.

[5] Malta had organised the Consulato del Mare (Consulate of the Sea) for the first time on 1 September 1697 per initiative of Grandmaster Perellós.

The pleas of Perellos to eliminate such prejudicial recommendations were considered legitimate by Pope Innocent XII who agreed to forbid them.

[4] Perellós dedicated many of his efforts to stop the attacks at sea by Ottoman pirates, who would sail along the coasts of Spain and Italy to plunder merchant ships and enslave civilians.

[4][13][14] One year later, the commanding knight Giuseppe de Langon,[15] surrounded Oran and with his sole vessel, which harbored a force of 50 cannons, traversed the entire enemy fleet despite the vain efforts of the Algerians to catch him.

[4][13] In 1709, the Grand Master's fleet anticipated and repelled eight Turkish vessels which attempted to infiltrate the island of Gozo.

This news reached Grand Master Perellós, who sent his emissary, the Great Prior Marc'Antonio Zondadari, to the Court of Rome to forward complaints about the incident.

[4] Possibly forewarned by Malta's preparations, the Ottoman sultan turned his attention to the Republic of Venice, on which he declared war in 1716.

In reply to a plea for assistance, Grand Master Perellós lent the Republic several galleys and five other warships to repel the Ottoman invasion.
