Where were styles of opera developed?

Styles of opera were developed primarily in Italy during the late 16th century, with early examples emerging in Florence and Venice. The genre later spread across Europe, leading to distinct styles such as German opera, French opéra, and English opera. Each region infused its cultural elements, resulting in diverse forms and traditions, such as the grand operas of France and the lyric dramas of Germany. Over time, opera evolved to incorporate various influences, including nationalism and modernism, reflecting broader musical trends.
