Sažetak The creation and development of Ingra from its ambitiously conceived but modest beginnings to its transition into a significant business association with high international rating, is presented in form of a documented and analytical overview. Individual stages of Ingra's development and operation, in the former country and in independent Croatia, are separately presented. Status-related, organizational and other changes in Ingra are described. Stages marked with greatest successes are presented together with stages of stagnation and business difficulties.
