Ci okrutni wikingowie (Strrraszna Historia)

The mix of comedy and education in the book kept me engaged, but I wonder what motivated the author to blend these styles for kids.

I found myself recalling the funny anecdotes long after reading. Are there other books that use humor so effectively to teach history to children?

Balancing accuracy with comedy seems tricky, and I'd love to know how much research or creative license went into these stories.
