Sveabolaget was founded in the 1870s, receiving its first ship in 1872. Most of early Svea ships were
steamers used as freighters around the world, carrying whatever cargo they could find from any port to any other port. In addition to these Sveabolaget soon starter operating cargo and passengers around the coast of Sweden and in the Baltic Sea. In 1918 the company (which by this time had changed its name to Stockholms Rederi AB Svea) started collaboration with
Finland Steamship Company and
Steamship Company Bore on routes between Sweden and Finland. In the 1930s the company radically expanded its freight operations, the size of its fleet growing to approximately 100 vessels. After
World War II Rederi AB Svea began developing
ferry traffic from southern Sweden to
Denmark and
Germany under the banners of
Trave Line,
Skandinavisk Linjetrafik and
Linjebuss. At the same time the company also began operating large ocean freighters. Between 1946 and 1964, Svea was the majority owner of
Waxholmsbolaget, the operator of passenger ferries in the
Stockholm archipelago. The first modern car-ferries were delivered for Svea in the 1960s. In 1966 Rederi Ab Svea began a joint car/passenger ferry line from Sweden to the
United Kingdom with
Swedish Lloyd and
Ellerman's Wilson Line, but withdrew from the joint service already in 1969, selling its sole ship in that service, , to Swedish Lloyd. Svea faced hard times in the 1970s and in 1975 50% of Svea shares were sold to
Rederi AB Nordstjernan (the parent company of Johnson Line). From 1975 onwards Svea operations were heavily rationalised. In 1976 Trave Line was merged with the trains-ferry operations of
Swedish State Railways to form
Saga Line. In 1980 large mergers were made in the Linjebuss small-ferry operations, bringing Linjebuss together with lines operated by the Swedish State Railways and a Danish company under the name
Scandinavian Ferry Lines. In the same year
TT-Line started joint operations with Saga Line and
TT-Saga Line was formed. In 1981, following financial difficulties, Rederi AB Svea sold its shares in TT-Saga Line and Scandinavian Ferry Lines, and in the end of the year the company itself was merged into Johnson Line. Further on Johnson Line merged with
Effoa in 1990 to form
EffJohn. ==Ships==
