Pope Urban III
The earliest written mention of the town dates back to the 12th century, when Saxo Grammaticus in Gesta Danorum refers to it as "Portus Mercatorum", which translates into Merchants' Harbour or in the Danish of the time "Købmannahavn". In a letter from 1186, Pope Urban III refers to the city as "Hafn", but this is probably just a shortened version of the full name.
