Why was the spanish tragedy called the spanish tragedy?

"The Spanish Tragedy," a play by Thomas Kyd, is titled so because it reflects the themes and settings associated with Spain, particularly through its exploration of revenge, honor, and the complexities of justice. The title also conveys a sense of national identity during a time when Spain was a powerful empire, and the play's dramatic elements resonate with the violent and tragic aspects of the Spanish society depicted. Additionally, the term "Spanish tragedy" became associated with a specific genre of dramatic literature that emphasized intense emotions and moral dilemmas, influencing later works in English drama.
