Louis Rudolph was the youngest son of Duke Anthony Ulrich of Brunswick-Wolfenbüttel and his consort Princess Elisabeth Juliane of Schleswig-Holstein-Sonderburg-Norburg, daughter of Duke Frederick of Schleswig-Holstein-Sonderburg-Norburg. He became a major general in the service of the Habsburg emperor Leopold I in 1690 and was promptly captured in the Battle of Fleurus by the forces of King Louis XIV of France. After being released the same year, his father gave him the Brunswick County of Blankenburg as a present, with the consent of his eldest son Augustus William, insofar violating the primogeniture principle laid down by the late Duke Henry V.
When in 1707 Prince Anthony Ulrich managed to betroth Louis Rudolph's daughter Elisabeth Christine to the Habsburg archduke Charles VI, his elder brother Emperor Joseph I raised the County of Blankenburg to an immediate principality. Louis Rudolph's status as an Imperial prince (Reichsfürst), however, was limited as his vote in the Imperial Diet was not hereditary and depending on the Welf Electorate of Brunswick-Lüneburg (Calenberg line).
On the death of brother Augustus William in 1731, Louis Rudolph also inherited Wolfenbüttel, thus ruling both principalities in personal union. He relocated his residence to Wolfenbüttel, the capital of the inherited bigger principality. In the few years of his rule, Louis Rudolph managed to restore the finances, after Augustus William had almost ruined the state.
Louis Rudolph died without male issue in 1735. He was succeeded by his first cousin, Duke Ferdinand Albert II, who had married Louis Rudolph's youngest daughter, Antoinette Amalie.
