Infanta: The Short, Remarkable Life of Catalina Micaela

by Magdalena S. Sanchez

The first full biography of Catalina Micaela, infanta of Spain and duchess of Savoy

Catalina Micaela was the younger daughter of Philip II and granddaughter of Catherine de Medici. Aged just seventeen, Catalina married Carlo I, duke of Savoy, and moved from the royal court in Madrid to Turin to begin a new life as a duchess.

Overlooked by historians and little known today, Catalina was nonetheless a key figure in sixteenth-century Europe. A woman of intelligence, forceful personality, and strong feeling, she energetically and effectively governed her husband's dukedom during his long absences from Turin on military campaigns. In this widely researched account, Magdalena Sánchez traces Catalina's life from her childhood to her early death shortly after giving birth to her tenth child. Drawing on thousands of letters Catalina exchanged with her husband, Sánchez paints an intimate portrait of a young Spanish woman adapting to a new husband, a new land, and the demands of governance.

Catalina Micaela, second daughter of Elisabeth of Valois and Philip II of Spain, and granddaughter of Catherine de’ Medici, was born in October 1567. In March 1585 she married Carlo Emanuele, duke of Savoy, a man she felt beneath her, but would go on to fall deeply in love with. Their marriage was to be interrupted by wars that kept them apart for months at a time. During Carlo’s absence, Catalina was left in charge of the duchy, acting as her husband’s lieutenant while running the household. Over the course of their marriage, Catalina was pregnant more than she was not, giving birth ten times in 12 and a half years. At least 3,127 letters were sent between the couple. The exchange ended abruptly with Catalina’s death in November 1597, aged only 30. At the memorial service held in Madrid, a sermon described the infanta and her husband as ‘two souls with the same will and two bodies in one’.

Despite the rich source material available in archives and published collections, including the thousands of letters, Catalina Micaela has been largely ignored by scholars. Most have focused on her older sister, Isabel, apparently their father’s favourite. Nevertheless, it was claimed that grief at his second daughter’s death shortened Philip’s life.

The letters, along with supplementary accounts of court life, are the treasure trove of information which inform Magdalena S. Sánchez’ extraordinary and engaging work of scholarship, the first full biography of Catalina. We get to know Catalina and Carlo intimately, and find out about Philip’s patience for a daughter who (thankfully) would defy his orders to burn the letters he sent her. Those letters were delivered by a surprisingly quick postal service: same or next day delivery for letters up to 35 miles away. Sánchez also reveals a strange culture of gift-giving: upon the birth of her first son, Catalina was presented with the finger of St Catherine in a crystal case decorated with jewels. Sánchez paints a vivid picture of the young infantas hearing their future marriage prospects being discussed in the court, at an age when today’s children would be in pre-school. Nevertheless, the princesses seem very close to their family, despite the ever-changing cast of characters, thanks to the constant spectre of death cutting relationships tragically short.

I really tried to finish this book, I made it through more than half... but in the end, I just couldn’t continue. It was simply too dry and, honestly, quite boring. I’m used to reading academic works and essays, so I don’t mind a serious or scholarly tone, but this felt like a step beyond that.

The book goes into extremely detailed descriptions of very mundane aspects of court life, what the king’s daughters studied, who taught them, what they ate, and similar everyday details. While these elements can add context in moderation, here they felt overwhelming and, at times, unnecessary, making the reading experience feel slow and tedious.

It’s a shame, because I was genuinely interested in learning more about Catalina Micaela—both as a Spanish infanta and later as Duchess of Savoy. Unfortunately, this book didn’t manage to bring her story to life in a compelling way for me. I’m sure it may appeal to readers looking for very detailed and random facts, but for my taste, it lacked narrative energy and engagement.

The younger daughter of Phillip II of Spain, Catalina was raised an infanta until her marriage at 17 made her Duchess of Savoy, her position at her death at the age of 30. In between, she wrote thousands of letters, which form the basis of Sanchez's study of her. The surviving letters between Catalina and her husband Carlo reveal an intimate look at their marriage and their partnership in ruling Savoy, where Catalina was often regent while Carlo fought various wars. Told chronologically, Sanchez also focuses on important cultural aspects to flesh out Catalina's world. She examines Spanish court etiquette and its integration into the Savoy court, the art of letter writing, governing by letters, courtship and child-raising, and the physical aspects of Catalina's Catholicism - particularly in regards to relics like the Shroud of Turin.
