Purpose: In the second half of the 19th century, Iran gradually established its ties with the global market and the country became a lucrative market for foreign goods. Tvmanyants Brothers Company, an Armenian enterprise, operated a wide range of activities, including transport, trading, services, building, manufacturing, banking and agriculture, mainly in the northern territory and in partnership with Russia. This paper discusses the company's operations in Iran and its impact on the domestic economics.Method/Research Design: Library and archival resources are consulted to collect data for analysis.Findings: The Company was in a favorable financial situation, was involved in a wide range of activities, and operated relatively independently. However, political and economic instability in the country, and lack of support from the government for its activities, led to reluctance for investing large amounts of capital in Iran. This was intensified by foreign competitors having an upper hand in the domestic economy of the country, a colonial attitude, and a lack of clear economic policy on the part of the government. Such factors forced the company to engage more in foreign trade, e. g. importing goods instead of playing a role in the economic development of the country.
