The siege of Larache, in 1689, was undertaken by an army of Morocco under 'Alawid Sultan Ismail Ibn Sharif against the Spanish forces of Charles II, which had ruled the city for almost 80 years since its cession in 1610.

With the arrival of Ismail Ibn Sharif to the throne,[1] Morocco lived its hours of glory since it succeeded in centralising power and putting down the rebellions of rebel tribes.

[3] In 1689, Mawlay Ismail raised a strong army of 30,000 horsemen to recapture Larache, while the Spaniards had a garrison made up of 2,000 soldiers and 200 guns present in the fortress to protect the city.

Military operations began on 14 July 1689, and a month later, in August 1689, the Moroccan army completely surrounded the city, it was commanded by the Caid Ali ben Abdallah.

For example, on 10 October 1689, he affirmed that the Moroccans had "two mines ready to play" and that two thousand Spaniards were on the spot, including two hundred volunteers.

[4] The capitulation was negotiated in Meknes with Mawlay Ismail by Gaspar Gonzáles, who was an envoy of the governor of Larache, Fernāndo Villorias y Medrano himself, who had been captured during the siege.

After the confirmation of this exchange, the consul of France in Salé Jean-Baptiste Estelle affirmed that it was "A beautiful agreement concluded" in February 1691.

The former soldiers of the Spanish garrisons based in the coastal towns of Morocco, captured by the Moroccans, were converted to Islam by the hundreds[dubious – discuss].
