Formed in 1862 by Donald Currie as Donald Currie & Co. to run a regular sailing ship service to India and familiarly known as "Currie's Calcutta Castles".

The first steamships entered service on the India route in 1872 and the same year, a passenger and private mail service from the UK to South Africa was inaugurated.

In 1876 the company became Castle Mail Packet Co. Ltd. and a joint mail contract was awarded together with the Union SS Co.

Calls at Flushing began in 1889 resulting in the grant of a contract to carry Dutch mails to South Africa and in 1900 Castle Line merged with the Union SS Co. to form Union-Castle Mail SS Co.
