Mambo was originally developed by Miro, a company based in Melbourne (Australia), in 2000. An interesting history of the project is published in the Joomla! Developer Blog. “In an era when PHP-Nuke reigned supreme, Miro correctly identified that there was a lack of substance for business oriented sites.

Miro publicly released its code under the names of Mambo Site Server and later Mambo Open Source at version 3 in April 2001.”

In 2005 work began on version 4.5.3 but, in August, a dispute developed within the Mambo Steering Committee and the entire Core Team left the project, to give birth to Joomla! 1.0 in September 2005.

Currently the Mambo Open Source Project is supported by the Mambo Foundation, a non-profit corporation whose purpose is to provide support and protection for the development of the Mambo software system.

Mambo is written in PHP, and requires a MySQL database for storage of content. It’s made available under the GNU GPL (General Public License).
