some state laws that refer to lodging operators as innkeepers. The Inns of Court and Inns of Chancery in London started as ordinary inns where barristers met to do business, but became institutions of the legal profession in England and Wales. Advent of the modern pub It was not until the 19th century that pubs as we know them today first began to appear. Before this time alehouses were largely indistinguishable from private houses and the poor standard of rural roads meant that, away from the larger towns, the only beer available was often that which had been brewed by the publican himself. With the arrival of the Industrial Revolution, many areas of the United Kingdom were transformed by a surge in industrial activity and rapid population growth. There was huge demand for beer and for venues where the public could engage in social interaction, but there was also intense competition for customers. Gin houses and palaces were becoming increasingly popular, while the Beerhouse Act of 1830 resulted in a proliferation of beerhouses. By the mid-19th century, pubs were being widely purpose-built, allowing their owners to incorporate architectural features which distinguished them from private houses and made them stand out from the competition. Many existing public houses were also redeveloped at this time, borrowing features from other building types and gradually developing the characteristics which go to make pubs the instantly recognisable institutions that exist today. In particular, and contrary to the intentions of the Beerhouse Act, many drew inspiration from the gin houses and palaces. Bar counters had been an early adoption, but ornate mirrors, etched glass, polished brass fittings and lavishly tiled surfaces were all features that had first made their appearance in gin houses. Innovations such as the introduction of hand pumps (or beer engines) allowed a greater number of people to be served in less time, while technological advances in the brewing industry and improved transportation links made it possible for breweries to deliver their products far away from where they were produced. Tied house system The latter half of the 19th century saw increased competition within the brewing industry and, in an attempt to secure markets for their own products, breweries began rapidly buying local pubs and directly employing publicans to run them. Although some tied houses had existed in larger British towns since the 17th century, this represented a fundamental shift in the way
