The Union-Castle Line was a British shipping line that operated a fleet of passenger liners and cargo ships between Europe and Africa from 1900 to 1977. It was formed from the merger of the Union Line and Castle Shipping Line. It merged with Bullard King and Clan Line in 1956 to form British & Commonwealth Shipping, and then with South African Marine Corporation (commonly referred to as Safmarine) in 1973 to create International Liner Services, but maintained its separate identity throughout. Its shipping operations ceased in 1977. Predecessor lines The Union Line was founded in 1853 as the Southampton Steam Shipping Company to transport coal from South Wales to Southampton. It was renamed the Union Steam Collier Company and then the Union Steamship Company. In 1857, renamed the Union Line, it won a contract to carry mail to South Africa, mainly the Cape Colony. The inaugural sailing of the Dane left Southampton on 15 September. Meanwhile, Donald Currie had built up the Castle Packet Co. which traded to Calcutta round the Cape of Good Hope. This trade was substantially curtailed by the opening of the Suez Canal in 1869, and the Castle Line started to run to South Africa instead, later becoming the Castle Mail Packet Company. In 1872 the Cape Colony gained responsible government and its first Prime Minister, John Molteno, ordered a re-negotiation of the country's mail services. In 1876, keen to avoid either of the two main companies gaining a monopoly on the country's shipping, he awarded the South African mail contract jointly to both the Castle Mail Packet Company and the Union Line. The contract included a condition that the two companies would not amalgamate, as well as other clauses to promote competition, such as alternating services and speed premiums. This competition led to their shipping services running at unprecedented speed and efficiency. The contract was eventually to expire however, and the period of intense competition was later to give way to co-operation, including transporting troops and military equipment during the Boer War. Finally, on 8 March 1900, the Union Line and Castle Shipping Line merged, creating the Union-Castle Mail Steamship Company, Ltd, with Castle Shipping Line taking over the fleet. Union-Castle Line Union-Castle named most of their ships with the suffix "Castle" in their names; the names of several inherited from the Union Line were changed to this scheme (for example, Galician became ) but
