33 galleys against the Algerians.
In April 1669 the Spanish governor, the Marquis of del los Vélez expelled all the Jews who lived in Oran and Mers El Kébir sending them to be resettled in either Nice, and Livorno.
The Spanish rebuilt the fortress of Santa Cruz Fort to accommodate their city governors. "The fortifications of the place were composed of thick and continuous walls of over two and a half kilometers in circumference, surmounted by strong towers spaced between them," with a central castle or kasbah where the Spanish governor established his headquarters. The city under Spanish rule continued to grow, requiring enlargement of the city walls. In spite of the improved fortifications, the city was the object of repeated attacks. Notable in this regard, Moroccan Sharif Moulay Ismail tried to force his way past the defenses in 1707, only to see his army decimated.
Ottoman period
The Bey Othmane Mosque
The Spaniards occupied the city until 1708, when the Turkish Bey, Mustapha Ben Youssef (Bouchelaghem) took advantage of the War of Spanish Succession to drive them out.
In 1732, Spanish forces, under José Carrillo de Albornoz captured the city from Bey Hassan in the Battle of Aïn-el-Turk.
In the night after October 8, 1790, a violent earthquake claimed more than 3,000 victims in less than seven minutes. ThereafterCharles IV saw no advantage in continuing the occupation of the city, which had become increasingly expensive and perilous. He initiated discussions with the Bey of Algiers. A treaty handing over the city was signed on September 12, 1792. After another earthquake had damaged the Spanish defences, Bey Ben Othman's forces took possession of Oran on October 8 of the same year. In 1792, the Ottomans settled a Jewish community there. In 1796, the Pasha Mosque (in honour of Hassan Pasha, Dey of Algeria), was built by the Turks with ransom money paid for the release of Spanish prisoners
