This article examines the recent deposition of Dom Pedro II in Brazil and its potential impact on European monarchies. The author argues that the swift and unexpected Brazilian revolution demonstrates the fundamental weakness of monarchical institutions worldwide. He systematically analyzes various European thrones, from Portugal and Spain in the west to the Balkan kingdoms in the east, arguing that most face imminent threats from republican movements, military discontent, or dynastic instability.
