A brougham pronounced broom or brohm was a light, four-wheeled horse-drawn carriage built in the 19th century. It was either invented for Scottish jurist Lord Brougham or simply made fashionable by his example. It had an enclosed body with two doors, like the rear section of a coach; it sat two, sometimes with an extra pair of fold-away seats in the front corners, and with a box seat in front for the driver and a footman or passenger. Unlike a coach, the carriage had a glazed front window, so that the occupants could see forward. The forewheels were capable of turning sharply. A variant, called a brougham-landaulet, had a top collapsible from the rear doors backward.
In 19th-century London, broughams previously owned and used as private carriages were commonly sold off for use as hackney carriages, often displaying painted-over traces of the previous owner's coat of arms on the carriage doors.
The special characteristics of the brougham bear a distinct similarity to the London Public Carriage Office's Conditions of Fitness for a vehicle intending to be licenced as a taxi cab.
