The history of COMESA began in December 1994 when it was formed to replace the former Preferential Trade Area (PTA) which had existed from the earlier days of 1981. COMESA (as defined by its Treaty) was established 'as an organisation of free independent sovereign states which have agreed to co-operate in developing their natural and human resources for the good of all their people' and as such it has a wide-ranging series of objectives which necessarily include in its priorities the promotion of peace and security in the region.
