Friedrich Wilhelm II (1744-1797) married firstly Elizabeth of Brunswick-Wolfenbüttel (1746-1840), and then after their divorce in 1769 he married Frederica (1751-1805), daughter of Louis IX Landgrave of Hesse-Darmstadt, in the same year.
During Friedrich Wilhelm's brief reign (1786-1797), radical artistic changes took place in Prussia. His uncle, Frederick The Great, had clung onto the Baroque and Rococo styles up until the end of his reign, but Friedrich Wilhelm opened the gates to Neoclassicism. Berlin adopted Neoclassicism with vigour, and Johann Gottfried Schadow (1764-1850), Carl Gotthard Langhans (1732-1808) and David Gilly (1748-1808) became the new influential personalites at this period. Two years after Frederick The Great's death, Langhans began work on the Neoclassical Brandenburg Gate (completed in 1791) which symbolised a new era in Prussia.
