The province of Sindh and the people inhabiting the region are named after the river known as the Sindhu River before Independence and now called the Indus River. In Sanskrit, "síndhu" means "river, stream", and refers to the Indus river in particular. The Greeks who conquered Sindh in 325 BC under the command of Alexander the Great rendered it as "Indós", hence the modern "Indus". The ancient Iranians referred to everything east of the river Indus as "hind" from the word "Sindh." When the British arrived in the 17th century, they followed that regional example and applied the Greek name for Sindh to the entire South Asian region, calling it "India".
