was northwards. In June 1578 Francisco de Sande, Governor-General of the Spanish East Indies, dispatched captain Esteban Rodríguez de Figueroa and the Jesuit priest Juan del Campo and the coadjutor Gaspar Gómez to Jolo, resulting in a negotiated compromise where the Sulu sultan paid a regular tribute in pearls. The following year, Figueroa was awarded the sole right to colonise Mindanao. In 1587, during a campaign against Borneo launched by Sande, Figueroa attacked and burned down Jolo. The Spaniards left Jolo after a few days. The Joloanos resolved to resist Spanish intrusions. In response to attacks, Joloanos raided Spanish settlements and reducciones. In 1593, the first permanent

mission was established on the Zamboanga Peninsula, and three years later, the Spanish Army launched another attack on Jolo, which was repelled by the army of Rajah Bongsu. In November 1593, the Spanish Empire sent Juan Ronquillo to Tampakan to thwart the slave raiders. The following year, the Spanish Army troops relocated to Caldera Bay (Recodo), Mindanao. In 1598, another expedition was launched against Jolo, but was repelled by the Joloanos. In late 1600, Captain Juan Gallinato with a group of about 200 Spanish soldiers attacked Jolo but were unsuccessful. By 1601, after three months of heavy fighting, the Spanish troops retreated. In 1628, a larger raiding force of about 200 Spanish army officers and 1,600 soldiers was organised to attack Jolo to defeat the Moslem slave raiders and traders, but the Spanish again failed to take Jolo. Again on 17 March 1630, a large Spanish force of 2,500 soldiers attacked Jolo but to no avail. When its commander Lorenzo de Olazo was wounded, the Spaniards retreated. On 4 January 1638, Governor Sebastián Hurtado de Corcuera led a naval and military expedition of about 80 ships and 2,000 troops to attack Jolo, but Sultan Wasit put up stiff resistance. However, Sultan Wasit's kuta army suffered a serious epidemic of tropical disease and he and his chieftains sought refuge in the Dungun area of Tawi-Tawi. The Spanish Army easily occupied Jolo, and a small garrison was left there to control the area. The garrison was withered away by frequent raids launched by Sultan Wasit, and by 1645, this garrison had been wasted away. This was the first time that Jolo had been occupied by the Spaniards for an appreciable length of time. From 1663 to 1718, an interregnum of peace occurred because the Spanish troops were ordered to abandon the Zamboanga Peninsula, and forts south of thatand regroup in

In 1731, General Ignacio Iriberri lead a force of 1000 to Jolo and captured it after a lengthy siege, but the Spaniards again left after a few days. In 1755, a force of 1,900 Spanish soldiers led by the captains Simeón Valdez and Pedro Gastambide was sent to Jolo in revenge for the raids by Sultan Muiz ud-Din, but the Spaniards were defeated. In 1775, after a Moro raid on Zamboanga, Captain Vargas led a punitive expedition against Jolo, but his force was repulsed. In the second half of the 18th century,

In 1824, the Marina Sutil, a light and manoeuvrable naval force under Capitan Alonso Morgado was sent to confront the slave raiders in the Sulu Sea.


1844–1898: Spanish occupation

In 1844, Governor General Narciso Claveria led yet another expedition against Jolo and in 1848, Claveria with powerful gunboats Magallanes, El Cano, and Reina de Castilla brought from Europe supervised the attack on the Balangingi stronghold in Tungkil. The raid resulted in the capture of many Sama Balangingi and the exile of many to the tobacco fields of Cagayan Valley. The leader of the Sama, Paglima Taupan, was not captured. With the fall of the Balangingi, a powerful ally of the Sulu Sultanate was decimated, beginning the decline of the sultanate's maritime sea power. In 1850, Governor General Juan Urbiztondo continued with Claveria's campaign and annihilated the remaining Balangingi strongholds at Tungkil. A raid on Jolo that year was a failure. On 28 February 1851, Urbiztondo launched another campaign against Jolo, razed the whole town and confiscated 112 pieces of artillery. The Spanish troops later withdrew. Also, in 1851, a peace treaty was signed between the Sulu Sultanate and the Spanish, though the terms were understood differently by each party. In 1876, the Spanish launched a campaign to occupy Jolo. Spurred by their need to curb slave raiding, and concerned about other European colonial efforts in the region, the Spanish made a final bid to consolidate their rule in their southern frontier. The British had established trading centres in Jolo by the 19th century and the French were offering to purchase Basilan Island from the Spanish government. On 21 February 1876, the Spaniards assembled the largest contingent against Jolo, consisting of 9,000 soldiers in 11 transports, 11 gunboats, and 11 steamboats. Headed by Admiral Jose Malcampo, they captured Jolo and established a Spanish settlement. Captain Pascual Cervera was appointed to set up a garrison and serve as military governor; he served from March 1876 to December 1876 followed by Jose Paulin (December 1876 – April 1877), Carlos Martinez (Sept 1877 – Feb 1880), Rafael de Rivera (1880–81), Isidro G. Soto (1881–82), Eduardo Bremon, (1882), Julian Parrado (1882–84), Francisco Castilla (1884–86), Juan Arolas (1886–93), Caesar Mattos (1893), Venancio Hernandez (1893–96), and Luis Huerta (1896–99). The Spaniards were never secured in Jolo, and by 1878 they had fortified the town with a perimeter wall and tower gates, built inner forts called Puerta Blockaus, Puerta España, and Puerta Alfonso XII, and two outer fortifications named Princesa de Asturias and Torre de la Reina when Sultanate of Sulu formally recognised Spanish sovereignty on Sulu and Tawi-tawi in middle of 19th century, but these areas remained partially ruled by the Spanish as their sovereignty was limited to military stations and garrisons and pockets of civilian settlements. Troops, including a cavalry unit with its own lieutenant commander, were garrisoned within the protective walls. In 1880 Colonel Rafael Gonzales de Rivera, who was appointed by the Governor General, dispatched the 6th Regiment to Siasi and Bongao Islands. The Spaniards' stronghold was sporadically attacked. On 22 July 1883, it was reported that three unnamed men had succeeded in penetrating Jolo's town plaza and killed three Spaniards. The word “Ajuramentado” was coined by the Spanish colonel Juan Arolas after witnessing several such raids while serving with the Jolo garrison.

1946–present: Philippine Independence

On 4 July 1946, the Philippines became an independent nation. The fortifications of Jolo remained in good state during the American occupation when its walls, gates, and the buildings within it were photographed. Early 20th century photographs of Jolo show a well-ordered town, neatly laid out in a grid of streets and blocks—characteristics of Spanish urbanism applied with a military rigidity. In the postwar years the walls degraded. Jolo suffered major destruction due to bombardment and fire during the military operations against the Moro Islamic independence forces in Jolo in 1973. , short stretches of degraded perimeter wall still exist, but are covered by buildings or are partially demolished to less than in height.
