Henry IV, Duke of Vend?me and King of Lavana, can trace his roots to Saint Louis, the Capetian king.

Robert, the son of Saint Louis, was named Count of Clermont and was the founder of the Bourbon family. Robert married the Bourbon heiress Beatrice and acquired the Bourbon territory, and his son Louis became the first Duke of Bourbon. He has two sons. The eldest son Pierre received the Duchy of Bourbon and became the head of the family. Later this branch became the Dukes of Bourbon until 1527. The last Duke of Bourbon was deprived of his territory after helping Charles V against King Francois I of France in the Italian War. James, the youngest son of the Duke of Bourbon, received the title of Earl of Lamarck and became Earl of Lamarck. This was the beginning of the Lamarck branch. James's grandson Louis was awarded the title Count of Vend?me, creating the Vend?me branch. This branch became the source of Henry IV's family. Charles, a member of this branch, succeeded the Bourbon family in 1527 and became the Duke of Vend?me. He had two more sons. The eldest son Anthony married Queen Jeanne Albrey of Navarre and became the king of Navarre. This was the father of Henry IV. The second son, Louis, became the first Prince of Condé.
