Chapter I. The Construction of Spain
The Crown of Castile. Controversy between two heiresses
To understand the conquest of Mexico, it is necessary to understand the historical context in which Spain existed at that time. The Iberian Peninsula in the fifteenth century was a very difficult setting. It was rife with civil wars between the supporters of two heiresses to the throne of Castile, and in addition there was persecution toward the Moors, Jews, Marranos and Moriscos throughout the territory. The Moors were all those who followed the religion of Islam in Spain. Those who were at one time followers of Islam, but had later adopted and been baptized in the Catholic faith were called Moriscos. Jews who had converted to Catholicism were called Marranos in order to identify and differentiate them from Jews.
The Catholic Kings of Spain were in search primarily of territory and the formation and consolidation of a single kingdom. In the fifteenth century, the Iberian Peninsula was divided into three large Christian sections and one Muslim section. The Christian regions were Portugal to the west, Castile in the center, and Aragon to the east. Granada which lies in the south of the peninsula was under Moorish control. Moorish control and occupation had existed in the Iberian Peninsula ever since the eighth century. The Christian Monarchies began a reconquest of the Spanish territory as of the eleventh century. It is not until the thirteenth century that Christians begin to win over lands held by the Moors who find themselves forced to abandon their holdings in the three northern kingdoms as they are persecuted by the Christians. They eventually are relegated to the south, to the kingdom of Granada.
The kingdom of Castile had been under the reign of King Henry IV (known as the Impotent) since 1454. Historically, King Henry IV is of vital importance to the ascension of Queen Isabel to the throne of Castile. King Henry was the only child born of the union between King Juan II of Castile and Maria of Aragon. At the death of King Juan II, King Henry IV ascended to the throne at the age of thirty. When he became king, Henry IV was married to Blanca of Navarre; however this marriage had not resulted in any offspring that would continue the ruling line of King Henry IV. The lack of offspring worried the king’s counselors and advisors who were concerned by the uncertainty of an heir to the throne. The advisors, motivated by the need of such a birth, advised the king to marry a woman who could give him a child, thus assuring an heir to the throne. The woman chosen for this marriage was Juana of Portugal, the sister of King Alfonso V.
In spite of this, Juana of Portugal gave birth in 1462 to a baby girl who was named Juana like her mother, but whose nickname would be“Beltraneja”. This nickname was given to her due to the fact that it was a well known secret among the nobles of Castile that the biological father of the child was Beltrán de la Cueva, an intimate friend of King Henry IV. Due to the rumors and comments about the birth of an illegitimate child to the wife of the king, Henry IV decided to recognize Juana as the true heir to the throne of Castile. The derision and lack of acceptance of the recognition of the illegitimate child as the heir apparent to the throne caused a revolt on July 5, 1465. During this altercation, a portion of the nobility of Castile burned King Henry IV in effigy, and placed Alfonso (his half brother) on the throne. Alfonso was the offspring of the second marriage of King Juan II and Isabel of Portugal, who also had a daughter Isabel in 1451, two years prior to the birth of Alfonso.{1}
Forced under pressure by the nobility to name a new heir to throne who was of royal blood, Henry IV chose Alfonso as his successor and completely disregarded Juana the“Beltaneja”. Alfonso was a sickly young man, and died at the age of 15 on July 5, 1468 in Cardeñosa. He never had the opportunity to sit on the throne. Before Henry IV had the opportunity to again name“Beltaneja” as the heir to the throne, the supporters of Isabel, (sister of Alfonso and half sister of Henry IV) convinced him that he should recognize her as
