Who put up the death mark in Harry Potter and Goblet of Fire?

The Death Mark, or the Dark Mark, was not put up by a specific person in *Harry Potter and the Goblet of Fire*. It was a symbol used by Lord Voldemort and his Death Eaters.

Here's how it happened:

1. The Dark Mark is used to summon Death Eaters: Voldemort's followers used the Dark Mark as a way to summon each other and communicate.

2. The Dark Mark appears in the sky: During the events of the Triwizard Tournament, the Death Eaters used the Dark Mark as a way to signal their arrival and create chaos.

3. The Dark Mark is displayed as a sign of allegiance: Those who joined Voldemort would bear the Dark Mark as a symbol of their allegiance.

So, while no one person specifically put up the Dark Mark in the sky, it was a collective act of the Death Eaters.
