The Libertarian Alliance (LA) comprises two libertarian think-tanks in Great Britain that promote free-market economics and civil liberties. According to the websites of both organizations, â€œThe Libertarian Alliance is a non-partisan group fighting statism in all its forms and working for the creation of a truly free society.â€ Between them, they have produced over 800 publications by over 280 authors. Free Life was formerly the LA's hardcopy journal. Most LA publications are now Internet based.
The original Libertarian Alliance was founded in 1977 by Mark Brady, Judy Englander, David Ramsay Steele and Chris Tame in Woking. It was an alliance of minarchists ("minimal statists") and classical liberals. The LA was not the continuation either the Radical Libertarian Alliance (founded by Mark Brady, Pauline Russell and Chris Tame) in late 1971 or the earlier Young Libertarians founded by David Myddelton in the late 1960s.
The principles of the LA were formulated by the founding members, and written out by David Ramsay Steele. While the LA had no official leader, it did have a chair, secretary and a treasurer. The Alternative Bookshop, formed in 1978, became the unofficial hub of LA activities for a time.
In 1982 a power struggle within the organization caused a split. Since then there have been two groups both calling themselves the Libertarian Alliance and using the same logo and using the phrase "Let a Thousand Libertarian Alliances Bloom!".  Although not always the case in the past, the two groups now have friendly relations and a number of English libertarians are members of both groups. However, reunification does not appear to be likely in the near future.
The other group maintains Libertarian-Alliance.Org.Uk.
