 Modern agriculture in Iran dates back to the 1820s, when Amir Kabir undertook a number of changes to the traditional agricultural system. Such changes included importing modified seeds and signing collaboration contracts with other countries. Polyakov's Bank Esteqrazi was bought in 1898 by the Tzarist government of Russia, and later passed into the hands of the Iranian government by a contract in 1920. The bank continued its activities under the name of Bank Iran until 1933 when incorporating the newly founded Keshavarzi Bank.
