* All ruling chiefs were assured that their kingdoms will not be annexed. However they had to accept the paramountcy of the British Crown which meant that the Indian rulers were subordinates to the British crown.
* In order to avoid any future rebellion, it was decided that the proportion of the Indians in the army will be reduced and the European soldiers will be increased.
* They decided to respect the religious and social practices of the Indians.
