Question: When was Catherine Of Saxe-Lauenburg's husband born?
Sentence (from "Gustav I of Sweden"): His 37-year rule, which was the longest of a mature Swedish king to that date (subsequently passed by Gustav V and Carl XVI Gustav) saw a complete break with not only the Danish supremacy but also the Roman Catholic Church, whose assets were nationalised, with the Lutheran Church of Sweden established under his personal control.
