Why might "Dido and Aeneas" have offended the English monarchy?

"Dido and Aeneas" may have offended the English monarchy primarily because it portrays a love affair between a native queen and a foreigner ending badly. This narrative can be viewed as politically sensitive, especially in the context of national pride and identity during the time it was composed. The story reflects themes of betrayal and loss, particularly in the context of Dido's tragic love for Aeneas, a Trojan hero. Such a depiction could be interpreted as undermining the values of loyalty and stability that a monarch might wish to promote.

The dynamics of a foreigner, Aeneas, causing the downfall of a native queen also carries implications of cultural invasion or disruption, which could be seen as problematic for a monarchy focused on national unity and strength. This representation of love and power could have made the ruling class unsettled, especially given the historical context of England's own political landscape.

In contrast, options suggesting a lack of traditional themes or the use of a foreign language do not capture the core reasons regarding the characters and their relationships as the primary source of potential offense. The tragic ending, while significant, is less about offending the monarchy and more about emotional resonance and artistic choices in storytelling.
