Etymology
The former name Bombay had its origins in the 16th century when the Portuguese arrived in the area and called it by various names, which finally took the written form Bombaim, still common in current Portuguese use. After the British gained possession in the 17th century, it was anglicised to Bombay, although it was known as Mumbai or Mambai to Marathi and Gujarati-speakers, and as Bambai in Hindi, Urdu.

History
Artifacts found near Kandivali in northern Mumbai indicate that these islands had been inhabited since the Stone Age. Documented evidence of human habitation dates back to 250 BCE, when it was known as Heptanesia (Ptolemy) (Ancient Greek: A Cluster of Seven Islands). In the 3rd century BCE, the islands formed part of the Maurya Empire, ruled by the Buddhist emperor, Aşoka. During its first few centuries, control over Mumbai was disputed between the Indo-Scythian Western Satraps and the Satavahanas.
