History of Vasai dates back to Puranic ages. The present day name of Vasai originates from Sanskrit, Sanskrit word "waas" meaning dwelling or residence. The name was changed to Basai by Muslims who occupied Vasai before the Portuguese. The Portuguese named it Baçaim. The Marathas named it Bajipura or Bajipur. The British named it Bassein and today it is called Vasai. The most significant past in Vasais history is the rein of the Portuguese, since they largely influenced or changed to what Vasai-Virar area is today. Historically, the entire region has attracted traders and merchants from Rome, Greece and Middle East. In 1295 AD the famous Marco Polo visited Thana/Vasai area.
