Several European nations saw these wars in India as an opportunity to increase their own power. Many nations, but mainly the Dutch, French and British, realized that by helping certain Indian princes (with weapons and soldiers, for example), they could turn the wars any way they wanted. Then When their new ally beat the enemy, they could demand rewards from the prince - perhaps land or goods! Further, if they ever fell out with him and fought against him, they usually ended up winning... and taking his territory!
