Task: Question Generation
Input (English): After about 1840, Georgian conventions were slowly abandoned as a number of revival styles, including Gothic Revival, that had originated in the Georgian period, developed and contested in Victorian architecture, and in the case of Gothic became better researched, and closer to their originals. Neoclassical architecture remained popular, and was the opponent of Gothic in the Battle of the Styles of the early Victorian period. In the United States the Federalist Style contained many elements of Georgian style, but incorporated revolutionary symbols.
Output (English): When was the Battle of the Styles contested?
