The Danish Crown abolished monopoly trading in 1786 and granted six communities around the country an exclusive trading charter. Reykjavík was one of them and the only one to hold on to the charter permanently. 1786 is thus regarded as the date of the city's founding. Trading rights were limited to subjects of the Danish Crown, and Danish traders continued to dominate trade in Iceland. Over the following decades, their business in Iceland expanded. After 1880, free trade was expanded to all nationalities, and the influence of Icelandic merchants started to grow.
