The Mughal Empire controlled Bengal by the 17th century. During the reign of Emperor Akbar, the Bengali agrarian calendar was reformed to facilitate tax collection. The Mughals established Dhaka as a fort city and commercial metropolis, and it was the capital of Bengal Subah for 75 years. In 1666, the Mughals expelled the Arakanese from Chittagong. Mughal Bengal attracted foreign traders for its muslin and silk goods, and the Armenians were a notable merchant community. A Portuguese settlement in Chittagong flourished in the southeast, and a Dutch settlement in Rajshahi existed in the north. Bengal accounted for 40% of overall Dutch imports from Asia; including more than 50% of textiles and around 80% of silks. The Bengal Subah, described as the ''Paradise of the Nations'', was the empire's wealthiest province, and a major global exporter, a notable center of worldwide industries such as muslin, cotton textiles, silk, and shipbuilding. Its citizens also enjoyed one of the world's most superior living standards.
