Johan of Schleswig-Holstein (9 July 1583 – 28 October 1602) 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.[1] 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.
