Jacob Ulfeldt

Jacob Ulfeldt was a Danish diplomat and member of the Privy Council from 1565. He is mostly known for his very troubled diplomatic journey into Russia in 1578 during which he concluded an unfavourable treaty with Tsar Ivan IV (1530–1584) that brought him to disgrace at home. His bitter attempts of getting satisfaction only damaged his case. However, his account of his Russian travels is still considered a main source of Danish-Russian relations as well as of 16th-century Russia. He was the father of Jacob Ulfeldt (1567–1630).
