What groups was Mysore fighting in the later half of the 18th century?
There were several other kingdoms which ruled over parts of India in the later medieval period prior to the British occupation. However, most of them were bound to pay regular tribute to the Marathas. The rule of Wodeyar dynasty which established the Kingdom of Mysore in southern India in around 1400 CE by was interrupted by Hyder Ali and his son Tipu Sultan in the later half of the 18th century. Under their rule, Mysore fought a series of wars sometimes against the combined forces of the British and Marathas, but mostly against the British, with Mysore receiving some aid or promise of aid from the French.
