Why did the port of Surat decline at the end of 18^th century?

The port of Surat declined at the end of the 18th century because:

• The Britishers gained a monopoly over certain trades and controlled the export and import.

• The connection of the inland water network system with the ports, to continue trade, was disrupted as the Indian products gradually started to lose its market.

• The local bankers who financed the trade were going bankrupt and trade suffered.
