Everything was upset though with the overthrow of the much-maligned King Charles X (the man who famously said he would rather saw wood than be a constitutional monarch) in the July Revolution which unseated the senior Royal Family line. Princess Caroline was forced to go into exile in Great Britain. However, anyone who counted her out was sorely mistaken. She was determined to see the old royal line restored and her son crowned King of France. He had already been proclaimed and she always stressed to him and those around her that he was the legitimate French sovereign. Family connections helped her cross the continent back to Naples. Soon she was busy with a conspiracy to launch a royalist uprising in France to restore her son, the nominal King Henri V of France and Navarre.
Her primary confederate in this enterprise was the Vicomte de Saint-Priest. In 1832 the two of them led an attempted royalist rebellion in the famously loyal Vendee region and in Provence against the Orleanist "King of the French" Louis-Philippe. Unfortunately for them the would-be counterrevolution was a complete failure and both were arrested. Princess Caroline was arrested and thrown in prison but released the following year when she gave birth to the daughter of the Italian Duke della Grazia whom she had married in secret after returning to Naples. The two of them bought a villa and settled down to as normal a family life as possible, having three more children, until the nationalist unification of Italy forced them into hard times. The Princess and would-be Queen Mother of France finally died in Styria, Austria in 1870; the last person to attempt to restore the Bourbon monarchy by counterrevolution.
