Who married Marguerite de Navarre?

Marguerite de Navarre (French: Marguerite d'Angoulême, Marguerite d'Alençon; 11 April 1492 – 21 December 1549), also known as Marguerite of Angoulême and Margaret of Navarre, was a princess of France, Duchess of Alençon and Berry, and Queen of Navarre by her second marriage to King Henry II of Navarre. Her brother became King of France, as Francis I, and the two siblings were responsible for the celebrated intellectual and cultural court and salons of their day in France. Marguerite is the ancestress of the Bourbon kings of France, being the mother of Jeanne d'Albret, whose son, Henry of Navarre, succeeded as Henry IV of France, the first Bourbon king. As an author and a patron of humanists and reformers, she was an outstanding figure of the French Renaissance. Samuel Putnam called her "The First Modern Woman".

Charles IV (1489 – 11 April 1525), duke of Alençon, was a French prince of the blood (prince du sang), military commander, governor and courtier during the reigns of Louis XII and Francis I. Born into the House of Valois-Alençon, Charles (known by his title of Alençon) was a distant relation of the royal family, but one of the closest agnates. After the ascent of Francis I in 1515, he was the heir presumptive until the birth of the king's first son in 1518. He undertook his early military service in the later campaigns of Louis XII. He fought at the recapture of Genoa in 1507, and the decisive defeat of the Venetians at Agnadello in 1509. That year he was married to Marguerite, the sister of the future king Francis I. At the ascent of Francis in 1515, he saw combat as the commander of the rear-guard at the famous battle of Marignano at which the Swiss army was annihilated, restoring French control over Milan.

In the coming years he participated in various court festivities and ceremonies, most notably the famous Field of the Cloth of Gold in 1520 at which the English and French sovereigns met. He was back on campaign in 1521, participating in the defence of the Northern French frontier against attack by Emperor Charles V. After the successful defence of Mézières in September the French army took the offensive, and Alençon led the royal vanguard on the march to Valenciennes, though there would be no battle with the Imperial troops. Alençon had a role to play in the disastrous French campaign of 1524–1525. In command of the royal rear-guard, Alençon followed the royal army into Italy where Pavia was laid siege to, after several months of siege with no progress, the Imperial army was ready to give battle on 23 February, and annihilated the French army, killing or capturing much of the French nobility at the battle including the king. Alençon was the only significant commander to escape the catastrophe, retreating back to France. Ashamed and defeated, he died of Pleurisy on 11 April 1525.

Heinrich II., genannt Henri d’Albret (* 18. April 1503 in Sangüesa; † 29. Mai 1555 in Hagetmau), war Titularkönig von Navarra. Er war der älteste Sohn von Jean d’Albret und Katharina von Navarra, der Schwester und Erbin des Königs Franz Phoebus von Navarra. Katharina brachte Heinrich II. im sogenannten Palacio de los Sebastianes in Sangüesa, also im Hause der navarrischen Familie Sebastián zur Welt. Das Haus existiert bis heute in der Calle Mayor 56, und die Fassade trägt unter anderem das Wappen der Familie Sebastián sowie eine Tafel zum Gedenken an Heinrich II.

Als Katharina 1517 im Exil starb, übernahm Heinrich ihre Ansprüche auf Navarra, die von König Ferdinand II. von Aragón seit langem bestritten wurden. Unter dem Schutz Franz’ I. von Frankreich nahm er den Titel eines Königs von Navarra an.

Nach ergebnislosen Beratungen in Noyon 1516 und Montpellier 1518 wurde 1521 ein aktiver Versuch unternommen, ihn auch de facto als Herrscher zu etablieren. Die französischen Truppen, die das Land besetzten, wurden jedoch schließlich von den Spaniern vertrieben.

1525 geriet Heinrich in der Schlacht bei Pavia in Gefangenschaft, aus der ihm jedoch die Flucht gelang.
