  This paper investigates the impact of changes in agents' beliefs coupled with
dynamics in agents' meta-roles on the evolution of institutions. The study
embeds agents' meta-roles in the BDI architecture. In this context, the study
scrutinises the impact of cognitive dissonance in agents due to unfairness of
institutions. To showcase our model, two historical long-distance trading
societies, namely Armenian merchants of New-Julfa and the English East India
Company are simulated. Results show how change in roles of agents coupled with
specific institutional characteristics leads to changes of the rules in the
system.
