Muwallil Wasit I of Sulu

After his death in 1650, another one of his daughters married Rajah Baratamay (also spelled Balatamay) of Buayan in 1657, further strengthening kinship between Sulu and Maguindanao.

[2] This however, did not stop the intricately knitted kinship and family ties the Sulu and Brunei Sultanates have with each other, dating as far back as the 14th century.

[2] In the late 1580s Pangiran Bongsu, as he was then called was sent to Bauang, the then, capital of Sulu to aid the Sulus militarily against the Spaniards who were once again attacking them.

Datu Acheh managed to escape but the act of treachery in the face of a diplomatic mission, perpetrated by the Spaniards incited anger among the Tausugs, and Sultan Wasit was quick to respond.

Upon landing on the shores of Jolo to attack it, de Olaso was badly wounded and the Spaniards lost heart and retreated, resulting in a decisive Sulu victory.

[2] The Sultan and his warriors launched still another invasion, this time, targeted only on the Island of Leyte, what they saw as the seat of Spanish power in the Visayas.

Sultan Wasit grew in wealth and prestige, as well as in fame, particularly among his Spanish rivals, who knew him by the name "Rajah Bongsu".

the following year, in January, the said priest was said to have escaped and travelled back to Manila to inform the Spanish government there of yet another possible attack by the 2 Sultanates, with reports of a fleet assembling at what is now Zamboanga City.

Don Juan Cerezo Salamanca, then Governor-general of the colony ordered an expedition be sent out at once, to curb the piratical raids in the region, and to establish a foothold in the area.

On 6 April 1635, Spanish captain Juan de Chaves was ordered to beachhead the south and established a military garrison in Samboangan, he named Bagumbayan, and became the forerunner of Ciudad de Zamboanga; This garrison in Samboangan led to the beginning of the defeat of Kudarat’s feared admiral, Datu Tagal, who had raided several pueblos in the Visayas.

For in 1636, Datu Tagal, admiral of Sultan Kudarat sent a massive fleet of "over 100 proas" with sailors and mainers gathered from all over Mindanao, Sulu and Borneo.

However, the short interlude between the last major Sulu-led Naval campaign in the late 1620s and the current, administrative phase of the Sultan was about to end.

[citation needed] Later that year, in 1636, The new Governor-general Sebastian Hurtado de Corcuera personally led an expedition against Kudarat and Tagal and triumphed over his forces at Lamitan and Lian.

for 8 long years, He and His son, Pangiran Sarikula (Sometimes spelled Salikula) along with the Datus of Sulu fought the Spaniards and reduced the garrison at Jolo.

Starting in the 1640s Sulu's main army was put under the command of his eldest son, and heir to the throne, Pangiran Salikula.
