In 1610, after his father's early death, he became Elector Palatine. After his initial education, Friedrich V went to Sedan, to the Court of his aunt, the Duchess of Bouillon, where he learned good manners and how to display his charms. The Palatinate was an important protestant nation, and so they found an important Protestant bride for him, Elizabeth, the daughter of King James I of England. 
Both Friedrich V and Elizabeth were only 17 when they were married, in 1613, in London; but it was a very happy marriage and was to produce thirteen children. In 1618 Friedrich V was invited to become 
King of Bohemia and, in 1619, he went with his wife to Prague where they became King and Queen of Bohemia, but for the duration of the winter only. 
The Austrians defeated the Bohemians and Friedrich V and Elizabeth had to escape to the Netherlands, as they had also lost The Palatinate to the Austrian Emperor. Louise Juliana, Friedrich V's mother, who was caring for their two eldest children, escaped to Wuerttemberg, taking the children with her. However, in fear for the Emperor, the Duke of Wuerttemberg asked her to leave and so they went to her daughter the Electress of Brandenburg in Berlin, leaving Heidelberg's luxury for the poverty of Brandenburg. 
After both had lived in exile for over twelve years without seeing each other, her son Friedrich V died also at 36 years of age like his father. It was ironic that, just at that time, the King of Sweden with 
his military might liberated part of the Palatinate which, however, would be ravaged by war for the following four years. The family residence with all its luxury went up in flames. For her security, 
Louise Juliana and her Palatine grandchildren went in 1638 to Koeningsberg (now Kaliningrad) in Prussia. Here she died aged nearly sixty-eight in 1644. However, it would take the Peace Treaty of 
Muenster in 1648 before her eldest grandson could return as the rightful Elector.
