The Duchy of Parma was in today’s northwest Italy and came into existence in 1545 when Pope Paul III made his illegitimate son Pier Luigi Farnese the Duke of Parma and Piacenza, territories that previously were a part of the Papal States. The House of Farnese reigned until 1731 when the male line went extinct. The duchy passed to Felipe V, King of Spain from the Spanish House of Bourbon whose second wife Elizabeth Farnese was the Farnese heiress. Felipe V made Carlos, his only son with Elizabeth Farnese, the Duke of Parma. However, in 1738, Felipe V traded the Duchy of Parma to the House of Habsburg-Lorraine for the Kingdom of Naples and Sicily and Carlos became King of Naples and Sicily.

In 1748, the Duchy of Parma was ceded back to the Bourbons. Infante Felipe of Spain became Duke of Parma and was the founder of the House of Bourbon-Parma, a cadet branch of the Spanish House of Bourbon.  In 1796, the Duchy of Parma was occupied by French troops under Napoleon Bonaparte. It remained in French hands until the defeat of Napoleon in 1814 when the duchy was given to Napoleon’s second wife, Marie-Louise of Habsburg-Lorraine. She reigned until her death in 1847 when the Duchy of Parma was restored to the House of Bourbon-Parma. In 1859, the Duchy of Parma was abolished during the Italian unification movement. It was merged with the Kingdom of Sardinia as part of the unification of Italy. In 1861, Vittorio Emanuele II, King of Sardinia was proclaimed the first King of the new, united Kingdom of Italy.

********************

Roberto I was the last Duke of Parma. As a not-quite-six-year-old, he succeeded his father who was assassinated, and then lost his throne five years later due to the Italian unification movement. Roberto Carlo Luigi Maria was born in Florence, Grand Duchy of Tuscany, now in Italy, on July 9, 1848. He was the second of the four children and the elder of the two sons of Carlo III, Duke of Parma and Louise Marie Thérèse of France. Roberto’s paternal grandparents were Carlo II Ludovico, Duke of Parma and Maria Teresa of Savoy (daughter of King Vittorio Emanuele I of Sardinia) His maternal grandparents were Charles Ferdinand, Duke of Berry (son of King Charles X of France) and Marie Carolina of Bourbon-Two Sicilies (daughter of King Francesco I of the Two Sicilies).

Roberto had three siblings:

• Princess Margherita of Bourbon-Parma (1847 – 1893), married Infante Carlos, Duke of Madrid, had five children
• Princess Alice of Bourbon-Parma (1849 – 1935), married Ferdinando IV, Grand Duke of Tuscany, had ten children
• Prince Enrico, Count of Bardi (1851 – 1905), married (1) Princess Maria Luisa of Bourbon-Two Sicilies, died three months after marriage (2) Infanta Adelgundes of Portugal, Duchess of Guimarães, no children

On March 26, 1854, while taking his usual afternoon walk through the streets of Parma, Roberto’s father Carlo III, Duke of Parma was attacked by two men who stabbed him in the stomach. After much suffering, which he endured bravely, thirty-one-year-old Carlo III, Duke of Parma died the following evening, March 27, 1854. Ireneo Bochi and Antonio Carra, Carlo’s murderers, escaped prosecution. They were briefly arrested but since they looked similar, witnesses were confused and deemed unreliable. Bochi and Carra did not act for political reasons but were hired assassins. However, exactly who paid them remains unknown.

Six-year-old son Roberto became Duke of Parma with his mother Louise Marie Thérèse as regent but he had a short reign. In 1859, the Duchy of Parma was abolished during the Italian unification movement. It was merged with the Kingdom of Sardinia as part of the unification of Italy. In 1861, Vittorio Emanuele II, King of Sardinia was proclaimed the first King of the new, united Kingdom of Italy. Roberto was the titular Duke of Parma and the pretender to the throne until his death in 1907.

Despite losing his throne, Roberto and his family had considerable wealth and traveled in a private train of more than a dozen cars. He had several residences including Schloss Schwarzau  (link in German) in Schwarzau am Steinfeld, Austria, Villa Borbone delle Pianore (link in Italian) in Capezzano Pianore, Italy, and Château de Chambord in Chambord, Centre-Val de Loire, France which he inherited from his maternal uncle Prince Henri, Duke of Bordeaux, Count of Chambord.

Roberto’s fortune made him a desirable husband but his half-first cousin once removed Princess Maria Pia of Bourbon-Two Sicilies was chosen as his bride. Maria Pia was the daughter of Ferdinando II, King of the Two Sicilies and his second wife Maria Theresa of Austria. The couple was married in Rome, Italy on April 5, 1869.

Roberto and his first wife Maria Pia of Bourbon-Two Sicilies had twelve children. Six of the children were mentally disabled, two died in infancy, and one was stillborn. Maria Pia, aged 33, died of puerperal fever (childbed fever) on September 29, 1882, in Biarritz, France a week after giving birth to her last child, a stillborn son.

Four months after Roberto’s death, the Grand Marshal of the Austrian court declared six of the children from his first marriage legally incompetent due to their severe mental disability at the request of his widow Maria Antonia. Elias, Roberto’s youngest son from his first marriage became the legal guardian of his six disabled elder siblings, served as regent for the claims of his two older disabled brothers and as Head of the House of Bourbon-Parma, and was Titular Duke of Parma from 1950 – 1959.
