The Portuguese Republican Revolution occurred in 1910, leading to the overthrow of the Portuguese monarchy. It was driven by widespread discontent with the monarchy's corruption, inefficiency, and inability to address social issues. The revolution was marked by a series of uprisings and protests, culminating in the declaration of the Portuguese Republic on October 5, 1910. Following the revolution, the monarchy was abolished, and King Manuel II fled to exile. The new republican government faced numerous challenges, including political instability and economic difficulties, which led to a turbulent period in Portugal's history, characterized by frequent changes in leadership and ongoing social unrest.
