Margaret Theresa was born on 12 July 1651 in Madrid as the first child of King Philip IV of Spain born from his second marriage with his niece Mariana of Austria. Because of this avunculate marriage, Margaret's mother was nearly thirty years younger than her father.
Margaret's paternal grandparents were King Philip III of Spain and his wife Archduchess Margaret of Austria. Her maternal grandparents were Ferdinand III, Holy Roman Emperor and his wife Infanta Maria Anna of Spain, the daughter of her paternal grandparents.
The marriage of her parents was purely made for political reasons, mainly the search for a new male heir for the Spanish throne after the early death of Balthasar Charles, Prince of Asturias in 1646. Besides him, the other only surviving child of Philip IV's first marriage was the Infanta Maria Theresa, who later became the wife of King Louis XIV of France. After Margaret, between 1655 and 1661, four more children (a daughter and three sons) were born from the marriage between Philip IV and Mariana of Austria, but only one survived infancy, the future King Charles II of Spain.
Margaret didn't develop the serious health issues and disabilities (because of the close consanguinity of her parents) that her younger brother had shown since his birth. During her childhood she was once seriously ill, but survived. According to contemporaries, Margaret had an attractive appearance and lively character. Her parents and close friends called her the "little angel". She grew up in the Queen's chambers in the Royal Alcazar of Madrid surrounded by many maids and servants. The Infanta loved candies, which she constantly hid from the physicians who cared for the health of her teeth. Both Margaret's father and maternal grandfather Emperor Ferdinand III loved her deeply. In his private letters King Philip IV called her "my joy". At the same time, Margaret was brought up in accordance with the strict etiquette of the Madrid court, and received a good education.
Betrothal and marriage

In the second half of the 1650s at the imperial court in Vienna the necessity developed for another dynastic marriage between the Spanish and Austrian branches of the House of Habsburg. The union was needed to strengthen the position of both countries, especially against the Kingdom of France. At first the proposals were for Maria Theresa, the eldest daughter of Philip IV, to marry the heir of the Holy Roman Empire, Archduke Leopold Ignaz. But in 1660 and under the terms of the Treaty of the Pyrenees, the Infanta was married to the French King; as a part of her marriage contract, she was forced to renounce her claims to the Spanish throne in return for a monetary settlement as part of her dowry, which was never paid.
Then began discussion about a marriage between Margaret and the Holy Roman Emperor Leopold I (who was her maternal uncle and paternal cousin). However, the Madrid court hesitated to agree to this proposal, because the infanta could inherit the Spanish crown if her little brother died. The count of Fuensaldaña, Spanish ambassador in France, suggested the infanta as a possible bride for King Charles II of England. However, King Philip IV rejected this idea, replying that the King of England should look for a wife in France.
In October 1662, the new Imperial ambassador in the Spanish Kingdom, Count Francis Eusebius of Pötting, began one of his main diplomatic assignments, which was the celebration of the marriage between the Infanta and the Emperor. Negotiations by the Spanish side were led by Ramiro Núñez de Guzmán, Duke of Medina de las Torres. On 6 April 1663, the betrothal between Margaret and Leopold I was finally announced. In the marriage contract signed on 18 December, besides the customary dowry, was particularly included, as a gift from her father, the famous Wittelsbach-Graff Diamond.[a] It was also stipulated that Margaret (in contrast with her older half-sister), should maintain her position in the line of succession to the Spanish throne and would pass her rights to her descendants. Before the official wedding ceremony (which, according to custom, had to take place in Vienna) another portrait of the Infanta was sent, in order for the Emperor to know his bride.
King Philip IV died on 17 September 1665. In his will, he did not mention Margaret's betrothal; in fact, the context in which the document was prepared suggests that the late monarch still hesitated to marry his daughter to his Austrian relative because he sought to ensure her rights as sole ruler of the Spanish crown in case of the extinction of his male line. Mariana of Austria, now Dowager Queen and Regent of the Kingdom on behalf of her minor son Charles II, delayed the wedding of her daughter. The marriage was agreed upon only after intense Imperial diplomacy efforts. On 25 April 1666, the marriage by proxy was finally celebrated in Madrid, in a ceremony attended not only by the Dowager Queen, King Charles II and the Imperial ambassador but also by the local nobility; the groom was represented by Antonio de la Cerda, 7th Duke of Medinaceli.

On 28 April 1666 Margaret traveled from Madrid to Vienna, accompanied by her personal retinue. The Infanta arrived at Denia, where she rested for some days before embarking on the Spanish Royal fleet on 16 July, in turn escorted by ships of the Order of Malta and the Grand Duchy of Tuscany. Then (after a short stop in Barcelona because Margaret had some health issues) the cortege sailed to the port of Finale Ligure, where arrived on 20 August. There, Margaret was received by Luis Guzman Ponce de Leon, Governor of Milan. The cortege left Finale on 1 September and arrived in Milan ten days later, although the official entry was not celebrated until 15 September. After spending almost all September in Milan, the Infanta continued the journey through Venice, arriving in early October in Trento. At every stop Margaret received celebrations in her honor. On 8 October the Spanish retinue arrived at the city of Roveredo, where the head of Margaret's cortege, Francisco Fernández de la Cueva, 8th Duke of Alburquerque officially handed the Infanta to Ferdinand Joseph, Prince of Dietrichstein and Count Ernst Adalbert von Harrach, Prince-Bishop of Trento, representants of Leopold I. On 20 October the new Austrian cortege left Roveredo, crossing the Tyrol, through Carinthia and Styria, and arrived on 25 November at the district of Schottwien, twelve miles from Vienna where the Emperor came to receive his bride.

On 5 December 1666, the solemn entry of the Infanta in Vienna took place and the official marriage ceremony was celebrated seven days later, on 12 December. The celebrations that took place in the Austrian capital on the occasion of the imperial marriage (which were among the most splendid of all the Baroque era) lasted almost two years.
Not far from the present Burggarten, the Emperor ordered the construction of an open-air theatre, with a capacity of 5,000 people. It is in this theatre, in July 1668 (on the occasion of Margaret's birthday), that the opera Il pomo d'oro (The Golden Apple), premiered. This opera, composed by Antonio Cesti, was called the "staging of the century" by contemporaries due to its magnificence and expense. The year before, the Emperor gave an equestrian ballet, where he personally mounted on his horse, Speranza; due to technical adaptations, the ballet gave spectators the impression that horses and carriages were hovering in the air.
Despite the age difference, Leopold I's unattractive appearance and Margaret's apparent goitre (a change of the thyroid gland), according to contemporaries they had a happy marriage. The Empress always called her husband "Uncle" (de: Onkel), and he called her "Gretl". The couple had many common interests, especially in art and music.
During her six years of marriage, Margaret gave birth to four children, of whom only one survived infancy:

Even after her marriage, Margaret kept her Spanish customs and ways. She did not speak German, and the arrogance of her native retinue led to a strong anti-Spanish sentiment among the imperial court. The courtiers openly expressed the hope that the weak Empress would soon die and thus give Leopold I the opportunity of a second marriage.
During her last pregnancy Margaret fell ill with bronchitis; this, along with her already weakened health due to four living childbirths and at least two miscarriages during her marriage, caused her early death on 12 March 1673, at the age of 21. She was buried in the Imperial Crypt, in Vienna. Only four months later, the widower Emperor –despite his grief for the death of his "only Margareta" (as he remembered her),– entered into a second marriage with Archduchess Claudia Felicitas of Austria, member of the Tyrol branch of the House of Habsburg.
After Margaret's death, her rights over the Spanish throne were inherited by her only surviving daughter Maria Antonia, who in turn passed them to her only surviving son Prince Joseph Ferdinand of Bavaria when she died in 1692. After Joseph Ferdinand's early death in 1699, the rights of inheritance were disputed by both Emperor Leopold I and King Louis XIV of France, son-in-law of King Philip IV. The outcome of the War of the Spanish Succession was the creation of the Spanish branch of the House of Bourbon in the person of King Philip V, Margaret's great-nephew.
