Antoine de Brichanteau dating history

Details

Antoine de Brichanteau, Marquis de Beauvais-Nangis (1552  – 1617) was a French noble, military commander, and royal favourite during the French Wars of Religion and early-17th century. Born into a noble Briard family, Beauvais-Nangis began his military career at a young age, serving during the third French War of Religion at Jarnac and Moncontour, among other engagements. At the former, his valour was recognised by the brother of the king, Anjou, who took him into his household. He fought at the famous Siege of La Rochelle in 1573 and joined Anjou in the Commonwealth when he was elected as king. Upon Anjou's return to France as King Henri III, Beauvais-Nangis was elevated as commander of the Picard regiments during the fifth War of Religion. In November of that year, he was granted the prestigious role of Maître de camp of the French Guard. In the sixth civil war, he fought at the siege of Hiers-Brouage. In 1579, he was dispatched on a diplomatic mission to Portugal. By his return, however, his relations were becoming increasingly frayed with the king. He had repeatedly found himself in dispute with other favourites of the king, and resented his lack of financial compensation for the diplomatic mission. In 1581, he embarrassed the king in a confrontation he undertook with Henri's brother Alençon, in which he killed several of the duke's men. Henri felt obliged to disgrace him, and in March of that year, he was relieved of the post of Maître de camp. He spent the next several years aggrieved on his estates in Brie.
