Christian the Younger of Brunswick-Wolfenbüttel (20 September 1599 – 16 June 1626), a member of the House of Welf, titular Duke of Brunswick-Lüneburg and administrator of the Prince-Bishopric of Halberstadt, was a German Protestant military leader during the early years of the Thirty Years' War, fighting against the forces of the Imperial House of Habsburg, Habsburg Spain, and the Catholic League. Life Christian was born in 1599 at the Gröningen Priory near Halberstadt (in today's Saxony-Anhalt), the third son of Duke Henry Julius of Brunswick-Lüneburg (1564–1613) with his second wife Elizabeth (1573–1626), daughter of the late King Frederick II of Denmark. After his father's death, he was educated by his maternal uncle, King Christian IV of Denmark, and attended the University of Helmstedt. After the death of his brother Rudolf in 1616, Christian, at the age of 17, was elected his successor as Lutheran administrator of the Halberstadt bishopric.

In 1620 Christian joined the army of Prince Maurice of Orange and fought in the Netherlands against a Spanish army. Later he raised his own army and, in liege to Frederick V, Elector Palatine, he carried out three significant battles: the Battle of Höchst (1622), the Battle of Fleurus (1622), and lastly at the Battle of Stadtlohn (1623). He participated in a number of plunderings and burnings along the France-Germany border and throughout the Netherlands. Christian fought alongside the Count of Mansfeld in the first two engagements, and suffered two losses to the Count of Tilly: an arguable one at Höchst, and his final one at Stadtlohn. Christian's major success was at Fleurus, where his actions directly led to the relieving of the Protestant stronghold of Bergen op Zoom. He died childless from wounds sustained in battle in 1626. Campaigns of 1622-23 In 1621, Christian was one of the few men to continue rallying behind Frederick V, who had only the year before claimed and been deposed from the throne of Bohemia following his crushing loss at the Battle of White Mountain. Frederick was still leader of the Protestant resistance rooted from the 1618 crushed Bohemian Revolution. What attracted Christian to the cause is arguable, but something that may have had to do with it was the fact that before his campaigning, Christian declared a
