During the history of 14th century Hungary, strangling ran in the royal family.
The new dynasty on the throne was the Anjou: Károly Róbert I (1301-1342), his oldest son Lajos I the Great (1342-1382), and Lajos' daughter Mária (1382-1395). For today's purposes, however, we will be focusing on Lajos' younger brother Endre, who had the misfortune of being married to one of the most notorious female rulers of the era: Joanna I of Naples.
Joanna, not a girl to give up easy, managed to lure her husband on a weekend getaway to one of their hunting castles. In the middle of the night there was a knock on the bedroom door; the good-natured Endre opened it unarmed (and no doubt a little groggy) and was immediately attacked by Italian soldiers. After throwing a few punches he tried to get back into the bedroom to his weapons, but Joanna locked the door behind him.
The people who attacked the duke knew that his ring made him invulnerable to weapons... So they ended up strangling him with a rope.
Loopholes. There is always one to every spell.
(Game of Thrones' got nothing on this.)
In the end, she did not win. She and Mária were captured as they were traveling the southern territories of the kingdom. In their captivity, according to the chronicles, Erzsébet was strangled in front of her daughter. Later Mária had the killer of her mother executed, but she didn't survive long: In 1395, she fell off her horse in an "accident" while heavily pregnant, and died in the resulting childbirth. Zsigmond of Luxembourg ended up on the throne after all.
Yeah. When you were a female member of the royal family, "win or die" was really how it went.
