Why did Russians come to Indian territory during 1840-1850?

During the 1840s, Russians ventured into Indian territory primarily due to their geopolitical interests in Central Asia and the desire to expand their influence in the region. This period coincided with the Great Game, a strategic rivalry between the British Empire and Russia for supremacy in Central Asia. Russians sought to establish closer ties with local rulers and explore potential trade routes, while also countering British expansion in India. Their incursions were often motivated by a mix of exploration, diplomacy, and military strategy.
