Why were foreign armies intersted in conquering India by 326BCE?

Foreign armies were interested in conquering India by 326 BCE primarily due to its immense wealth, fertile lands, and strategic location along trade routes. The region was known for its valuable resources, including spices, textiles, and precious metals, which attracted powers like the Persian Empire and later Alexander the great. Additionally, the fragmented political landscape of Indian kingdoms made it easier for foreign invaders to exploit divisions and expand their influence. The allure of fame and fortune also motivated these armies to seek conquest in this prosperous land.
