Isabella, the only daughter of John II., of Castile, and Isabella, of Portugal, his second wife, was born in Madrigal, Spain, in 1451. Upon the death of her father her elder half-brother succeeded to the throne in 1454, as Henry IV. The queen dowager retired from court life with her infant son Alfonso, and her daughter Isabella, then in her fourth year. The royal children were reared by a wise mother in the seclusion of the little town of Arevalo, until Isabella was twelve years old. How carefully the seeds of character were sown in these early years is shown by the after-fruits. Her fervent piety and unwavering faith, her strict integrity and self-abnegation, disarmed the enemies of her crown, as they disarm the unprejudiced historian of to-day. The verdict of four hundred years is still: "Her faults were the faults of her age, her virtues were her own." The quiet home life at Arevalo came suddenly to an end in 1463, when King Henry arbitrarily ordered the infantas, as all royal children are called in Spain, to repair to the palace as members of his court. Thus at the early age of twelve years Isabella entered upon her public career, and from thenceforth the eyes of the civilized world were turned upon her. Shortly after, a revolution deposed Henry and placed Alfonso upon the throne. Both kings had their followers, and the boy-king, eleven years old, rode on horseback at the head of his troops beside his appointed regent. But the crown was too heavy for the young victim, and Alfonso was one morning found dead in his bed. To Isabella, a beautiful girl of sixteen, the fallen crown was offered and urged; but in spite of the fact that the old standard had already been unfurled in her honor, and unmoved by the eloquence of the primate and the arguments of the first nobles of the land, Isabella, with a wisdom beyond her years, resolutely refused to take the throne. Her reasons baffled her advisers: "So long as King Henry lives none other has the right to wear the crown." She advised his reinstatement and promised to help redress the wrongs of which the nation had the unquestioned right to complain. An amnesty was declared and a reconciliation was effected; but not until Henry had consented to divorce his queen and to acknowledge Isabella as the heir-apparent to the throne in place of his reputed daughter, Joanna. The cortes, or parliament, was assembled to ratify the treaty, and at the same time, passed a resolution that the infanta was not to be coerced in her matrimonial alliance. In 1468, with great pomp and ceremony, Isabella was solemnly proclaimed Princess of Asturias, heir-apparent to the throne of Castile and Leon. She is described as of medium height, of fair complexion, regular features, auburn hair, clear blue eyes, and with a sweet but serious expression that told both sides of her character. She inherited from her father a desire for knowledge and a love of literature, and was herself a fine linguist. These graces of mind and person, added to her nearness to the throne, soon brought many ardent suppliants from the principal thrones of Europe for the honor of her hand. Her cousin, Prince Ferdinand of Aragon, was her wise choice, and to him she was married, notwithstanding her brother's opposition, in 1469. The brilliant wedding at Valladolid, in the presence of the nobility and about two thousand persons, closes the second period of her life. Five years intervened before the Princess of Asturias became Queen of Leon and Castile. Stormy years, for the angry brother instituted a fresh rebellion against her succession, and Isabella was again the peace-maker; years of poverty, also, for the heirs-apparent of Castile and Aragon had scarcely a competency for their daily needs. Isabella was residing in Segovia at the time of her brother's death; hence, in Segovia, with more than the usual solemnities which accompany the accession of a new sovereign even in Spain, she took the vows and was crowned Queen of Castile and Leon in 1474. During the first four years and a half of her reign civil war desolated her kingdom, for Joanna, the reputed daughter of Henry IV., again contested her right to the crown, supported by the King of Portugal, to whom she was affianced. But the same people who had said "Isabella shall be the heir-apparent," said now "Isabella shall rule over us," and conquered. The reign of Isabella, therefore, dates from 1479, when she was left in undisputed possession of her throne, rather than from 1474, when she wore her crown for the first time in Segovia. The same year that brought peace to the Queen of Castile elevated Ferdinand to the throne of Aragon.
No more important epoch marks the history of Spain than the union of the crowns of Castile and Aragon; it meant the end of petty principalities and powers, it meant united Spain. But the crowns were only linked together, for Isabella, even in her marriage contract, had maintained the independence of the crown of Castile and her individual right to rule over it. It was this loyalty to her inherited crown that won the love and confidence of her people and made them ready, when the need came, to die for Isabella of Castile. And it was this independence of her crown that enabled her to say at last to Columbus: "I will assume the enterprise for mine own crown of Castile," and "to the crown of Castile" belonged the first discovered territories in the New World.
Had the reign of Isabella been less distinguished for events of such momentous magnitude as to involve the future interests of the world, her personal life would yet furnish data for a series of volumes, so replete was it with stirring incidents and with heart-breaking sorrows. But the same mental strength and moral courage that made her eminent as a queen, made her remarkable also as a friend and mother. Prescott says: "Her heart overflowed with affectionate sensibilities to her family and friends. She watched over the declining years of her aged mother and ministered to her sad infirmities with filial tenderness; we have abundant proofs of how fondly and faithfully she loved her husband to the last; while for her children she lived more than for herself, and for them too she died; for it was their loss and their afflictions which froze the current of her blood before age had had time to chill it."
Five children, four daughters and one son, grew to maturity under her guiding influence. Isabella, the first born, and ever the favorite child of the sovereigns, was born in 1470. She was twice married, first to Alfonso, Prince of Portugal, who was killed by a fall from his horse within five months after their marriage. Seven years later she married his brother, Emanuel, King of Portugal. To the intense grief of her husband, her parents, and her kingdom, she died in 1498, just one hour after the birth of her son, the first and only heir to the kingdoms of Castile, Aragon, and Portugal. The little Prince Miguel did not live to fulfil the hopes that were centred in him, for he died, to the great grief of the nation, before he had completed his second year.
The only son of Ferdinand and Isabella, Juan, Prince of Asturias, was born in 1478. In his twentieth year he married the Princess Margaret, daughter of the Emperor Maximilian; but before the elaborate nuptial rejoicings had ended the young bridegroom died suddenly of a malignant fever.
The Infanta Joanna, born 1479, married Philip I., son of the German emperor, and became the mother of the great Emperor Charles V. of Germany, Charles I. of Spain. Her mental derangement, tending to permanent insanity, was a sore grief to the great queen, who nevertheless made her the heir to her crown, with Ferdinand as regent.
The Infanta Maria, born in 1482, married Emanuel, the King of Portugal, in 1600. Her daughter Isabella married her cousin, Charles V., and was the mother of Philip II.
The fifth and last child of Ferdinand and Isabella, Catalina, was born in 1485. She married, when scarcely sixteen, Arthur, Prince of Wales, son of Henry VII., but was left a widow within a year. By special dispensation from the Pope she married her brother-in-law in 1509, and is better known in history as Catharine of Aragon, first wife of Henry VIII., of England, mother of Mary I., or "bloody Mary." Knowing her Spanish parentage, we can better understand why she was such an ardent Roman Catholic. Strange that one so loyal to the forms of her religion should have been the innocent cause of the English Reformation! The injured queen, divorced, remained in England, a religious recluse, until her death in 1536.
