'Eight Brothers') (e)states were a group of jagirs (small feudatory estates, formally ranking below a proper princely state) of Central India during the period of the British Raj.
They belonged to the Bundelkhand Agency and all of them had been originally part of the princely state of Orchha.
After Rai Singh's death, the jagir went to his sons and it was divided into eight parts (hasht) among the brothers (bhaya) in order to form the following estates: Three jagirs were merged into the others, owing to lack of issue, a fourth would later be annexed by the British.
The British decided that the tribute levied by Jhansi should be paid through the Hasht-Bhaiya jagirs and that their rulers would keep and respect the traditional protocol towards the Maharaja of Orchha as head of the ruling families of the jagirs.
[1] In 1841, following the rebellion of Jagirdar Bakht Singh, the British authorities took possession of Chirgaon jagir, invoking the Doctrine of lapse.
