Infante Juan, Count of Barcelona

After his death in 1993, he was buried with honours due a king, under the name Juan III (his title if he had become king) in the Royal Crypt of the monastery of San Lorenzo del Escorial, near Madrid. His wife survived him by seven years.

When General Francisco Franco declared Spain a monarchy in 1947, he characterized it as a "restoration". However, Franco was afraid that Juan would roll back the Spanish State because he favoured constitutional monarchy, which would restore parliamentary democracy. As a result, in 1969, Franco passed over Juan in favour of Juan's son, Juan Carlos, who Franco believed would be more likely to continue the dictatorship after his death. Juan Carlos later surprised many by his support of democratising Spain. Franco and Juan did not have a good relationship, with the latter constantly pressing Franco to restore the monarchy. Relations soured further when Juan called Franco an "illegitimate usurper".

On 19 March 1945, he announced a manifesto in Lausanne, demanding he replace Franco: .mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}

In 1936, his father sent him to participate in the Spanish Civil War but he was arrested near the French border, and sent back by General Emilio Mola.

In March 1935, he passed his naval exams in gunnery and navigation, which would have entitled him to a lieutenant’s commission in the Royal Navy if he gave up his Spanish nationality. This, however, he refused to do.

He met his future wife at a party hosted by Victor Emmanuel III of Italy on the day before his sister (Infanta Beatriz) was to be married. He married Princess María de las Mercedes of Bourbon-Two Sicilies (1910–2000), known in Spain as Doña María de las Mercedes de Borbón Dos-Sicilias y Orleans, in Rome on 12 October 1935.

Juan was born at the Palace of San Ildefonso. His father was forced into exile when the Second Spanish Republic was proclaimed on 14 April 1931. Owing to the renunciations of his brothers Alfonso, Prince of Asturias, and Infante Jaime, Duke of Segovia, Infante Juan was thus next in line to the defunct Spanish throne. He thus received the title Prince of Asturias when he was serving with the Royal Navy in Bombay.

In 1931, Juan was subject to dynastic negotiations between the Alfonsists and the Carlists, concluded in so-called Pact of Territet; it has never been implemented. Juan became heir apparent to the defunct Spanish throne after the renunciations of his two older brothers, Alfonso and Jaime, in 1933. To assert his claim to the throne, following his father's death he used the title of Count of Barcelona, a sovereign title associated with the Spanish crown.

Infante Juan, Count of Barcelona (Juan Carlos Teresa Silverio Alfonso de Borbón y Battenberg; 20 June 1913 – 1 April 1993), also known as Don Juan, was a claimant to the Spanish throne as Juan III. He was the third son and designated heir of King Alfonso XIII of Spain and Victoria Eugenie of Battenberg. His father was replaced by the Second Spanish Republic in 1931. Juan's son Juan Carlos I became king when Spain's constitutional monarchy was restored in 1975.
