Sindh (Sindhi: سنڌ; Latin: Indus; Ancient Greek: Ἰνδός Indós ) is one of the four provinces of Pakistan and historically is home to the Sindhi people. It is also locally known as the "Mehran" and has been given the title of Bab-ul-Islam (The gateway of Islam). The name of Sindh is derived from the Indus River that separates it from Balochistan and the greater Iranian Plateau. This river was known to the ancient Iranians in Avestan as Indus, in Sanskrit as Sindhu, to Assyrians (as early as the seventh century BC) as Sinda, to the Greeks as Indos, to the Romans as Indus, to the Persians as Ab-e-sind, to the Pashtuns as "Abasind", to the Arabs as Al-Sind, to the Chinese as Sintow, and to the Javanese as the Santri.
