Before the arrival of the Spaniards in the 16th century, Pasig was part of the Muslim Sultanate with its capital in Tondo, which traded with Arab and Indian merchants. The local population at the site of the modern city, mainly consisted of ethnic Malays, Chinese who migrated from the southern outskirts of China during the Ming Dynasty and local Tinguyan tribes.
The majority of the population professed Islam.
