Pangasinan was first founded by Austronesian peoples who called themselves "Anakbanwa" by at least 2500 BC. A kingdom called "Luyag na Caboloan", which expanded to incorporate much of northwestern Luzon, existed in Pangasinan before the Spanish conquest that began in the 16th century. The Kingdom of "Luyag na Kaboloan" was known as the Wangdom of Pangasinan in Chinese records. The ancient Pangasinan people were skilled navigators and the maritime trade network that once flourished in ancient Luzon connected Pangasinan with other peoples of Southeast Asia, India, China, Japan and the rest of the Pacific. The ancient kingdom of Luyag na Caboloan was in fact mentioned in Chinese and Indian records as being an important kingdom on ancient trade routes.
