1838 in the United Kingdom

Sir Marc Isambard Brunel was a French-British engineer who is most famous for the work he did in Britain. He constructed the Thames Tunnel and was the father of Isambard Kingdom Brunel.

A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 19th century; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is incorrectly assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.

The Tolpuddle Martyrs were six agricultural labourers from the village of Tolpuddle in Dorset, England, who were arrested and tried in 1834 for swearing a secret oath as members of a friendly society. Led by George Loveless, the group had formed the Friendly Society of Agricultural Labourers during a labour dispute over wage cuts that reduced their income to near-starvation levels. Such unions were technically legal, but the British government, wary of organised labour, invoked an obscure 1797 law against "unlawful oaths" to bring charges. In R v Loveless and Others the men were convicted and sentenced to penal transportation in Australia. They were pardoned in 1836 after mass protests by sympathisers and support from Lord John Russell, and returned to England between 1837 and 1839. Most of the men later emigrated to Canada.

SS Great Western was a wooden-hulled paddle-wheel steamship with four masts, the first steamship purpose-built for crossing the Atlantic, and the initial unit of the Great Western Steamship Company. Completed in 1838, she was the largest passenger ship in the world from 1837 to 1839, the year the SS British Queen went into service.

Isambard Kingdom Brunel was an English civil engineer and mechanical engineer who is considered "one of the most ingenious and prolific figures in engineering history", "one of the 19th-century engineering giants", and "one of the greatest figures of the Industrial Revolution, [who] changed the face of the English landscape with his groundbreaking designs and ingenious constructions". Brunel built dockyards, the Great Western Railway (GWR), a series of steamships including the first purpose-built transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering.

The Great Western Steam Ship Company operated the first regular transatlantic steamer service from 1838 until 1846. Related to the Great Western Railway, it was expected to achieve the position that was ultimately secured by the Cunard Line. The firm's first ship, Great Western was capable of record Blue Riband crossings as late as 1843 and was the model for Cunard's Britannia and her three sisters. The company's second steamer, the Great Britain was an outstanding technical achievement of the age. The company collapsed because it failed to secure a mail contract and Great Britain appeared to be a total loss after running aground. The company might have had a more successful outcome had it built sister ships for Great Western instead of investing in the too advanced Great Britain.

The Great Western Railway's ships operated in connection with the company's trains to provide services to Ireland, the Channel Islands and France. Powers were granted by Act of Parliament for the Great Western Railway (GWR) to operate ships in 1871. The following year the company took over the ships operated by Ford and Jackson on the route between Wales and Ireland. Services were operated between Weymouth, the Channel Islands and France on the former Weymouth and Channel Islands Steam Packet Company routes. Smaller GWR vessels were also used as tenders at Plymouth and on ferry routes on the River Severn and River Dart. The railway also operated tugs and other craft at their docks in Wales and South West England.

Comrades is a 1986 British historical drama film directed by Bill Douglas and starring an ensemble cast including Robin Soans, Phil Davis, Keith Allen, Robert Stephens, Vanessa Redgrave and James Fox. Through the pictures of a travelling lanternist, it depicts the story of the Tolpuddle Martyrs, who were arrested and transported to Australia in 1834 for trying to improve their conditions by forming an early form of trade union. It was Bill Douglas's last film.

Steamboat services started on the Thames in around 1815 and for nearly 25 years were the main use of steam to carry passengers before the emergence of railways in the south of England. During this time at least 80 steamers are recorded in the Thames and the Steamboat Act of 1819 became the first statute to regulate the safety of the new technology for the public. Wooden boats driven by paddle-wheels, they managed during this time to establish themselves as faster and more reliable than the earlier use of sailing and rowing boats for passenger transport within the Thames estuary.

Vice-Admiral James Hosken was a British naval officer and a pioneer of ocean steam navigation. He joined the Royal Navy during the Napoleonic Wars, and after more than 20 years of service left to join the merchant navy and serve as captain of the steamships SS Great Western and the SS Great Britain. He returned to the Royal Navy to see service during the Crimean War.

A bronze statue of Isambard Kingdom Brunel, also known as Brunel Monument or the Isambard Brunel Monument, by Carlo Marochetti, stands on the Victoria Embankment in London, England, at the west end of Temple Place. The statue rests on a Portland stone pedestal, with flanking screens and benches, by the architect Richard Norman Shaw.
