Through Consanguinity

Henry's succession in 1589 proved far from straightforward. He and King Henry III were moving to besiege Paris at the time of the latter's death. The city and large parts of France, mostly in the north, were in the hands of the Catholic League, an alliance of leading Catholic nobles and prelates who opposed the Protestant Henry of Navarre as heir to the throne. Instead, they recognized Henry's uncle Charles of Bourbon as the heir, and on Henry III's assassination they declared Charles king. As a result, Henry IV was forced to fight a civil war to assert his position as king, followed by a war against Spain, which continued to question his legitimacy.

After the death of Charles of Bourbon, the Catholic League's failure to choose a replacement claimant to the throne, in combination with Henry IV's conversion to Catholicism, led to a general recognition of the king in France. Henry IV's successors ruled France until the French Revolution, then returned during subsequent Bourbon restorations, and they founded dynasties in Spain and the Kingdom of the Two Sicilies.

Bourbon claim to throne

Henry of Navarre was descended through his father from King Louis IX of France. Robert, Count of Clermont (d. 1317), the sixth and youngest son of Louis IX but the only son besides Philip III to produce a surviving line, had married Beatrix of Bourbon and assumed the title of sire de Bourbon. Bourbon was elevated into a duchy for Robert's son Louis, who became the first Duke of Bourbon.

At the death of Charles IV, Duke of Alençon in 1525, all cadet branches of the House of Valois had become extinct, with the only remaining Valois being the royal family itself. The chief of the Bourbons became the first prince of the blood, the closest to the succession to the throne should the immediate family of the king become extinct. At the death of Charles III, Duke of Bourbon in 1527, the Vendôme branch of the House of Bourbon became the senior line of the family. At that time, Charles de Bourbon was Duke of Vendôme. His son Antoine de Bourbon married the Queen of Navarre, a niece of King Francis I. Antoine's son, Prince Henry of Navarre, inherited this title on his death from an arquebus wound at the siege of Rouen in 1562.

The legitimacy of Henry of Navarre's claim to the throne was still questioned, however. In similar cases, the throne had earlier passed to successors with a much closer blood link to the throne. Louis XII had succeeded Charles VIII as his second cousin once removed in the male line. Francis I had succeeded Louis XII as his first cousin once removed in the male line. The successions were legally unproblematic because consanguinity was acknowledged in law to the tenth degree. Henry of Navarre, on the other hand, could claim only an agnatic relationship to Henry III in the twenty-second degree. When Henry had become the heir presumptive to the throne in 1584, on the death of Francis, Duke of Anjou, polemicist Jean Boucher had been among those who protested that such a distance in blood meant Henry's claim to the throne had effectively lapsed and that therefore the French States-General had the right to elect a new king.

When Henry was a boy, it seemed highly unlikely that he would ever inherit the throne of France since Henry II had produced four surviving sons. However, the prince of Navarre's pedigree gave him a special place of honour in the French nobility since all scions of the Bourbon line were acknowledged as the princes of the blood. As Head of the House of Bourbon, Henry was officially the First Prince of the Blood, the first nobleman of the kingdom.

The importance of the princes of the blood had been demonstrated when Antoine of Navarre's uncle Francis, Count of Enghien (d. 1546) had commanded the victorious royal armies at the battle of Ceresole in 1544. It was to be further demonstrated when Antoine of Bourbon's last surviving brother, Cardinal Charles (d. 1590), was chosen by the Catholic nobles as King of France in the face of Henry IV's Protestantism. Catherine de' Medici had ensured her regency of the nine-year-old King Charles IX in 1560 only by making a deal with Antoine of Bourbon, who many considered had the right, as First Prince of the Blood, to be the regent.

In a kingdom that the Salic Law excluded women from succession to the throne, Catherine had overcome prejudice against government by a woman and been elected governor (gouvernante) of France with sweeping powers. However, she accepted that none of her three daughters would ever inherit the French throne. By 1572, only two of her sons remained alive; she brokered a marriage between her daughter Margaret and Henry, who that year became King Henry III of Navarre after the death of his mother, Jeanne d'Albret, while she was buying clothes for the wedding in Paris. The marriage was intended to unite the interests of the house of Valois with the house of Bourbon.

Henry of Navarre always emphasised the significance of his blood, rather than religion, when he challenged the Guise-led Catholic League. After the League forced Henry III to sign the Treaty of Nemours, which excluded Navarre from the succession, in July 1585, the latter issued a manifesto condemning the pact as:

A peace made with foreigners at the expense of the princes of the blood; with the House of Lorraine at the expense of the House of France; with rebels at the expense of obedient subjects; with agitators at the expense of those who have brought peace by every means within their power [...] I intend to oppose it with all my heart, and to this end to rally around me [...] all true Frenchmen without regard to religion, since this time it is a question of the defence of the state against the usurpation of foreigners.

The pull of such propaganda remained so potent that even after 25 years of civil war, an English agent reported that after that and similar declarations by Henry, "many good Catholics flocked to his standard".
