Why did the leaders of Mecca want t o keep polytheism?

The leaders of Mecca wanted to maintain polytheism primarily to preserve their economic and political power, which was closely tied to the pilgrimage business centered around the Kaaba, a site dedicated to multiple deities. Polytheism allowed them to attract worshippers from various tribes, ensuring a steady flow of wealth and influence. Additionally, embracing a single monotheistic faith, such as the one proposed by Muhammad, threatened their established social order and authority. Thus, they resisted the rise of monotheism to protect their interests and maintain their status.
