This book presents first of all the reasons that led African countries that share the French language to harmonize their business legislation. Indeed, after the accession of these States to international sovereignty, it appeared that the legislation in each of these States was that of the colonizer made applicable to the colonies according to the rule of legislative speciality. The result was a disparate law, varying from one colony to another. This situation has led, everywhere, to legal and judicial insecurity which each State must remedy by adopting a simple, modern legal arsenal adapted to the situation of each country.Moreover, the objective of African economic integration, to which the newly independent African States have subscribed, calls for a uniform law for the said States, especially since a legally integrated space offers several advantages and facilitates African economic integration.The book also presents the process that led to the creation of the ORGANIZATION FORTHE HARMONIZATION OF BUSINESS LAW IN AFRICA (OHADA).
