Summary
Updated 2026-08-18

Johan of Schleswig-Holstein was the youngest son of Frederick II of Denmark and Norway and Sophia of Mecklenburg-Schwerin. He went to Russia in 1602 as the bridegroom of Boris Godunov's daughter Ksenia (Xenia), but fell ill and died before the marriage could take place. It is possible that Boris Godunov's ministers may have poisoned him. The cancelled marriage between John and Ksenia was an attempt to ally Denmark-Norway with the Russian Empire.
