Why princess urduja is unhistorical data?

Princess Urduja is often considered unhistorical because there is a lack of concrete evidence to support her existence as a historical figure. Most accounts of her come from folklore and legends, particularly in the Philippines, which blend historical facts with myth. Scholars suggest that her story may have been embellished over time, making it difficult to distinguish between reality and fiction. Consequently, while she is a significant cultural symbol, her historical authenticity remains questionable.
