Louis Armand I, Prince of Conti

Louis Armand I de Bourbon (1661–1685) was Prince of Conti, from 1666 to his death, succeeding his father Armand de Bourbon.

In 1680 Louis Armand married Marie Anne, Mademoiselle de Blois, a daughter of Louis XIV and Louise de la Vallière. The bride and groom were respectively 13 and 15 years old at the time. Since neither of them had been instructed what to expect on their first night together, it ended up in disaster with the young princess fleeing in despair and the prince not wanting to share the bed of a woman again.

He served with distinction in Flanders in 1683, and against the wish of the king went to Hungary, where he assisted the Imperialists to defeat the Turks at Gran in 1683. He died in Fontainebleau from smallpox which he contracted from his wife. While she recovered after some time, the prince succumbed after five days.

Having no descendants, he was succeeded as Prince of Conti by his younger brother, François Louis de Bourbon (1664–1709).
