In each of the books, a fictional diary of a real female figure of royalty as a child throughout world history was written by the author.
The Royal Diaries was a spin-off of Scholastic's popular Dear America series.
The Royal Diaries has covered many famous women in royalty, including Jahanara, Marie Antoinette, Eleanor of Aquitaine, Queen Elizabeth I, Mary, Queen of Scots, Isabella I of Castile, Cleopatra VII, the Grand Duchess Anastasia Nikolaevna, Catherine the Great, Empress Elisabeth, and Queen Victoria.
In 2000, HBO created three TV films based on three of the Royal Diaries books: Elizabeth I: Red Rose of the House of Tudor (England, 1544), Isabel: Jewel of Castilla (Spain, 1466), and Cleopatra: Daughter of the Nile (Egypt, 57 BC).
The title characters were portrayed by Tamara Hope, Lisa Jakub and Elisa Moolecherry, respectively.
