A government overthrow, also known as a coup d'état, occurs when a group or individual forcibly removes the existing government from power. This can happen through various means, including military action, political maneuvering, or popular uprisings. The goal is often to replace the current leadership with a new regime that may have different political ideologies or objectives. Overthrows can lead to significant changes in a country, affecting its laws, economy, and social structure. Historical examples include the overthrow of Ferdinand Marcos in the Philippines in 1986 and the Iranian Revolution in 1979. These events can result in instability, conflict, or, in some cases, a transition to democracy.
