Fish, caviar, and rice are important products; tobacco, fruit, and tea are also produced. Textiles are manufactured. There is a dam, an airport, and a natural-gas pipeline. Gilan was ruled by the Mongols in the 13th and early 14th cent. and was incorporated into Persia by the Safavid dynasty in the late 16th cent. It was occupied by Russia from 1722 to 1732. In the 19th cent. it was divided among Iran, Great Britain, and Russia. It was (1920–21) a Soviet republic before being returned to Iranian control in 1921.
