By a treaty concluded between Persia and Muscat in 1856 it was stipulated that Bander Abbasi town and district and the islands were to be considered Persian territory and leased to Muscat at an annual rent of 14,000 tomans (£6000).
The treaty was to have been in force for twenty years, but in 1866 the Persians took advantage of the assassination of Seyed Thuweni, the sultan of Muscat, to instal as governor of Bander Abbasi and district a nominee of their own who agreed to pay a rent of 20,000 tomans per annum.
Further difficulties arising between Persia and Muscat, and the ruler of the latter, then in possession of a powerful fleet, threatening to blockade Bander Abbasi, the Persian government solicited the good offices of the British government, and the lease was renewed for another eight years upon payment of 30,000 tomans per annum (then about £12,00o).
Landowners must possess land of at least 1000 tomans (~2oo) in value, merchants and tradesmen must have a fixed and well-known place of business or shop with an annual value of not less than the average values in the localities where they are established.
The shahs civil list amounts to 500,000 tomans (~ioo,ooo).
