The Infantado family

The Mendoza family, originally from Mendoza (Alava), is one of the most important and influential in the history of Spain. Its main peerages are the Duke of Infantado and Marquess of Santillana. According to the Spanish historian tells Luis Suarez in his book “Nobility and Society” is one of the few noble families who were already before the thirteenth century and survived that fateful century plagues and civil wars.

La Casa del Infantado is a native to the Crown of Castile Spanish noble house. Its name comes from the Duchy of Infantado, with the title Greatness of Spain.

The Duchy of Infantado is a Spanish noble title granted by the Catholic Monarchs on July 22, 1475 to Diego Hurtado de Mendoza, Marquis of Santillana II. In 1520 he was awarded the Greatness of Spain first class. Names the Casa del Infantado. The Catholic Monarchs also created in 1479 the County of Saldaña, who formerly occupied for the heirs of the Duchy of Infantado. In those moments, the son and heir of Diego Hurtado de Mendoza, was Iñigo López de Mendoza, who became the I Count of Saldana, afterwards became II Duke of Infantado.

From that moment all the heirs of the Duchy, were counts of Saldaña, also bearing the Marquis de Santillana, as the first title that the Mendoza family held.
Don Diego Hurtado de Mendoza and Figueroa (1415 – 1479) was the first son and heir of Don Iñigo Lopez de Mendoza (first Marquis of Santillana) and was named after his grandfather. It was, then, the second Marquis of Santillana and Count of Real de Manzanares. He was born in Guadalajara and died in Manzanares el Real. From boy his father sent him to pacify the valleys of the Asturias de Santillana.

Enrique IV did not get along with Diego and although first he was expelled from Guadalajara in 1459,  he awarded him in 1460 the title of Count of Saldaña for the firstborn of his house (in payment to support Mendoza) returning Diego to Guadalajara in 1462. Diego also fought on the border of Granada.

Like all Mendoza was first supporter and guardian of Princess Juana “la Beltraneja”, but following the appointment of his brother Peter as Cardinal he decided in 1473 to the side of Isabel and Fernando, after a secret interview with Fernando (road of Duanas “walked two long leagues alone”) and Isabel (near Segovia), Diego with all his family in May 1474, will support the future Catholic Monarchs. In these “political shenanigans” Diego followed the line marked by his brother Cardinal Pedro.

In the civil war for the succession to the death of Henry IV, his performance was appreciated by the Queen. So he joined in 1475 the title (and wealth) of Marqués de Santillana the Duke of Infantado, who later would be part of the “Greatness of Spain of First Class” and entitled to be covered with a hat in the presence of the King. The full title is “Duke of the Five Towns of the State of the Infantado,” highlighting among these villas the Alcocer, Salmeron and Valdeolivas. The currency of the Dukes was “Giving is lordship, receivig is servitude”, indicating that their wealth did not need to serve a higher lord for them to reward any change. Mendoza led by the Duke and the great Cardinal in 1476 to help win the decisive battle of Toro.

The Duke had possessions in both Castile and Aragon, but its political relevance is not comparable to that of his brother Pedro (the Great Cardinal), and his father. He improved the castle of Manzanares and possessions in Guadalajara capital, was devoted to the Monastery of Sopetrán. He and his descendants were, in practice, the owners of the city of Guadalajara, but not their masters, as the city of Guadalajara was from Realengo. He married in 1436 with Brianda de Luna, a cousin of his father’s old enemy Condestable D. Alvaro de Luna, which began the houses of Mendozas and Lunas began to join.

The sixth Duchess of Infantado, Doña Ana de Mendoza, was inherited by his grandson, Rodrigo Díaz de Vivar, who was viceroy of Sicily, and had no children. At his death, the duchy was in possession of the family of Silva for some years, but in 1841 the direct line of succession, which had hitherto been more or less hereditary, stopped, and the house of the Infantado, along with all his titles, were handed to the Osuna. On the death of the Duke of that name, which occurred in 1882, the title passed to the person of Andrés Avelino Arteaga, who belonged to another lineage, the Valmediano, and that was the seventeenth Duke of Infantado.

The Manzanares el Real new Castle

The New Castle of Manzanares el Real, also known as Castle of the Mendoza, is a palace-fortress erected in the fifteenth century in the town of Manzanares el Real (Madrid, Spain) and by the reservoir of Santillana and by the Sierra de Guadarrama.

Its construction began in 1475 on a Romanesque-Mudejar hermitage and today is one of the best preserved castles in the Community of Madrid. It was built on the edge of the Manzanares river, as residential palace of the House of Mendoza, in the vicinity of a primitive fortress, abandoned once the new building was constructed.

The castle now houses a museum of the Spanish castles and is home to a collection of tapestries. It was declared a Historic-Artistic Monument in 1931. It is owned by the Duchy of Infantado, though its administration and use corresponds to the Community of Madrid.

La Calahorra castle

The Calahorra Castle is perched on a hill 1,250 meters above sea level that visually dominates the Marquis of Cenete in the Spanish town of La Calahorra, Granada province, autonomous community of Andalusia. As for its historical value, stands as a testimony of a key chapter in the history of the region of Cenete in the sixteenth century, it mayorazgo founded by Cardinal Mendoza in favor of his son Don Rodrigo Díaz de Vivar. Represents an anachronistic case in a time when the monarchy ordered to tear down the strongholds to consolidate its presence to the people, and in order to avoid the continuation of the relationships of the old feudal nobility, orders that have made this exception will perpetuate the powerful military house of Mendoza.
