TRADITION VS SCHOLARSHIP
The answer
Agree. Daniel 5 presents Belshazzar as king and as Nebuchadnezzar's son. Babylonian records make him the son of Nabonidus, who was not of Nebuchadnezzar's line. They show him as crown prince, ruling in Babylon while his father was away at Teima. They never call him king, so "co-regent" is a modern label, and a debated one. Daniel being offered only 'third' place in the kingdom (5:16) fits that picture, without proving it.
Why it’s interesting
In ancient usage, 'son' could mean a successor or descendant rather than a literal child. So scholars debate how neatly the account lines up with the records. It's a lively test case for reading Daniel as history.

Not just the stories, but the history, authorship, and scholarship behind it.
