The line of Don Carlos

Birth of Don Carlos
On 1545, Maria Manuela would give birth to a healthy son baptized as Carlos, but Maria Manuela would die after giving birth due to the complications of the pregnancy and immediately Philip, Prince of Asturias decided to marry Maria of Portugal, the half aunt of Maria Manuela so that Infante Carlos would be raised by someone close to his mother.

Maria Manuela was said to have smiled at the birth of Infante Carlos before she died as she believed that her son would have a great life in which she would not be mistaken as he would be able to rule Portugal after the death of King Sebastian of Portugal but he is not able to be the King of whole Iberia or Spain.

The discovery of a new isle
Around the time of Maria Manuela’s death the Portuguese led by Pero Fidalgo have discovered a new island which is called by the Portuguese would Luçon due to the trading port called as Luçon in the island, both the islands of Caesaria Caroli(Maluku Besar) and Luçon(Selurong) would be an issue by the Castilians and the Portuguese that aside from the fact that they are in the Portuguese side in Tordesillas, the Portuguese actually landed in those islands, Philip, Prince of Asturias would later advice his father, Charles V in the 1550s after the birth of Sebastian of Portugal which was years after the Villalobos expedition not to claim Luçon, Mollucas, and Caesarea Caroli as his son Don Carlos could inherit Portugal anytime, knowing the state of his nephew, Sebastian being frail and being raised in strict catholic tradition from his sister, Joanna of Spain.

Charles V and Philip, Prince of Asturias did not know that the most powerful rulers of Caesaria Caroli had already had sworn fealty with Spain and signed a blood compact.

Around this time, the Chams from Champa which is affected by Vietnamese expansion in their territories would start to migrate to Selurong or what the natives and nearby people generally call as the Tagalog lands which would promote the religion of Islam in Selurong, the Chams would be invited by the Borneans to settle in Selurong which would slowly cause the formation of the Sultanates in Selurong and the retreat of Bornean control in Selurong, the Chams would settle and assimilate to the native culture.


Luzon and Mindanao are assigned under the Portuguese crown for a time in this TL, the term Tagalog is not used as a word for an ethnolinguistic group as the OTL Tagalogs are called as Kumintangs.

Death of Maria of Portugal and the arrival of Elizabeth Tudor
After giving birth to two daughters, Isabella(May 10, 1548) and Catherine(November 6, 1551), Maria of Portugal’s body would give up as the pregnancies, miscarriages and her touring of the countries have worn her down, 1551 a week after Catherine of Spain was born Maria of Portugal dies.

The life that Philip, Prince of Asturias made for himself is shattered after the death of Maria of Portugal, the second wife of Philip II on 1551 and was depressed at the death of his wife and he would mourn the death of his wife, Maria of Portugal as he had mourned his wife Maria Manuela, he would say why would he have to experience the death of his own wife Maria Manuela of Portugal.

Mary I of England would win against Jane Grey and she had told Charles V to marry her but declined and wanted her to marry Philip, Prince of Asturias, she would see Mary Seymour and Kate Parr’s fate she would see the problems of deciding to marry and having children of her own at an advanced age and decided to marry Elizabeth Tudor or Elizabeth of England to Philip, Prince of Asturias to secure heirs via her sister, this decision would have allowed her to live until 1570 and make England Catholic again, the marriage contract of Elizabeth Tudor with Philip, Prince of Asturias would include the joined inheritance of the Netherlands with England and Philip, Prince of Asturias and Elizabeth of England would marry by proxy in 1555.

Elizabeth Tudor would arrive to Spain to marry Philip, Prince of Asturias and married him in 1556 and adopted the name Isabel, who Philip II was not fond off at first but tried his best to be a good husband even if he had experienced the deaths of his two wives, Maria Manuela of Portugal and Maria of Portugal.

After the abdication of Charles V in 1556, Philip II of Spain and his wife, Elizabeth of England were crowned as King and Queen of Spain. and Elizabeth would be the first queen of Philip II but the first one to crowned as Queen of Spain.

Elizabeth of England and Anna of Poland
Philip II would sire two children with Elizabeth of England named Anna of Austria(January 10, 1157), and Thomas of England(December 2, 1558), Elizabeth of England would die a few weeks after the birth of Thomas and Philip II would have issues with Bona, Dowager Queen of Poland and decided to settle his issue with Bona by marrying her eldest unmarried daughter Anna of Poland in the end of 1559 with the contract that Anna of Poland would be given Bari, Anna of Poland would be crowned as Queen of Spain as soon as she had married Philip II of Spain.

The Children of Elizabeth of England would be under the care of Anna of Poland who herself is older than Philip II of Spain.

Henry II of France would betroth his daughter, Elizabeth of France to Charles, Prince of Asturias as the result of the Treaty of Cateau Cambresis, which would result in a marriage in the end of 1560 when Elizabeth of France left France to marry Charles, Prince of Asturias who himself is also the heir of Portugal aside from the Spanish Kingdoms which would have meant some stability in the French borders for a long time as long as Elizabeth of France lived but Anna of Poland would outshine Elizabeth of France on the Spanish court even if Elizabeth of France is younger than Anna of Poland.

Anna of Poland would give birth to two daughters, Sophia (June 10, 1562) and Bona(June 6, 1568) which would add another batch of brides for Philip II to use as treaty baits.

Don Carlos and Elizabeth of France
In 1560, Elizabeth of France made her way to Spain, where she entered into matrimony with Charles, Prince of Asturias, the designated heir to the Kingdom of Portugal. Despite their apparent dissimilarities, with Elizabeth being notably more intelligent and outgoing than her husband, their union promised to be a valuable addition to the royal court.

Following the demise of Francis II of France in 1560, Catherine of Medici sought the hand of Isabella of Spain for her son, a request that was granted by Philip II.

The relationship between Elizabeth of France and Anna Jagellonica was very difficult due to their contrasting upbringings and she would correspond with her mother, Catherine of Medici about her issues with Anna Jagellonica and gave her information about Anna Jagellonica which she would use in arranging the marriage of one of her sons to one of the daughters of Anna Jagellonica and Philip II.

Tragically, Elizabeth of France gave birth to a son named Philip on June 2, 1565, only to pass away shortly after the childbirth. Charles, Prince of Asturias, subsequently remarried to Anna of Austria


I am not giving him an inbred heir, one inbred heir is enough.

The coronation of Carlos I of Portugal and Miguel Lopez de Legazpi
Sebastian I of Portugal would die in the end of 1568, which would start the end of independence of Portugal as a country in Iberia and Charles, Prince of Asturias would be crowned as the King of Portugal, knowing about that news later, Miguel Lopez de Legaspi would correspond with King Philip II of Spain and Charles I of Portugal and asked for instructions in how to proceed.

Miguel Lopez de Legaspi would be given the instruction by Philip II of Spain and Charles I of Portugal to act both as the governor of the Portuguese East Indies for Luzon and Mindanao which would enable Miguel Lopez de Legaspi to broke deals with the Sultanates in Luzon and take the suzerainty of the Island of Mindanao for Portugal.

Miguel Lopez de Legaspi would subjugate and absorb the Madyaas Confederacy start to make relations with the Sultanate of Selurong and Kumintang, Sultan Sulayman III of the Kumintang Sultanate would give Manila and its environs to the Spanish while the Sultanate of Selurong to the North of Kumintang would be hostile to the Spanish and Miguel Lopez de Legaspi would start to make relations with the Kingdom of Caboloan, an enemy of the Sultanate of Selurong as it is a threat to its territory as the Muslims of Caboloan are under the Sultanate of Selurong.

Luyag na Caboloan
The interaction between the Kasikis of Caboloan and Juan Lopez de Salcedo facilitated the establishment of trade relations between Pangasinan or Luyag na Kaboloan and the Portuguese and Spanish. Despite this, Caboloan faced challenges such as harassment from Japanese and Chinese pirates, as well as conflicts with Muslims from the Sultanate of Selurong, which surrounded Caboloan.

In 1573, the Spanish successfully repelled the Invasion of Limahong of Manila, prompting Limahong to retreat and try to settle in Caboloan. By 1574, Caboloan allied with the Spanish and the Portuguese would expel Limahong, resulting in Caboloan coming under Spanish Suzerainty.

In 1574, the Kasikis of Caboloan converted to Christianity and aligned with the Spanish and Portuguese, persuaded by Salcedo's assistance in expelling the Chinese. He recognized the Spanish and Portuguese as enemies of the Sultanate of Selurong, as the Muslims in his territory acknowledged the Sultan of Selurong as their rightful ruler not the ruler of Caboloan.

The transition of Caboloan to Portuguese Crown Suzerainty in 1575 led to a war between Selurong and Kaboloan in 1576, resulting in the Spanish annexing the Territory of Samtoy in the North of Caboloan under the Portuguese Crown. This territory was subsequently renamed as Nueva Segovia by the Spanish but under the Portuguese Crown, with Vigan as its capital. Additionally, a claimant to Brunei named Pengiran Seri Lela sought Spanish assistance, igniting further conflicts in subsequent years.
