Two years before, the exhibition Magnetic Fields had been held at the Guggenheim Museum in New York and Miró bronzes at the Hayward Gallery of London.

In February of the same year Miró had painted the triptych The Hope of a Condemned Man, concerned about the conviction of the activist Salvador Puig Antich, finally executed in garrotte on 2 March 1974.

Juan Carlos de Borbón, then Prince of Spain, was 5 years old who had sworn allegiance to Francisco Franco as his future successor as head of the state.

Miró had created artworks that were critical with the concept of authority, around the character Ubu Roi back in 1966.

His Highness the Prince consists of two large timbers put together and topped with a curved goat horn.
