A military coup is a sudden and often illegal seizure of power by the armed forces of a country. This typically occurs when military leaders decide to overthrow the existing government, often citing reasons such as political instability, corruption, or failure to maintain order. The military may take control of key government institutions and impose martial law. During a coup, the military may detain political leaders and restrict civil liberties. The outcome can lead to significant changes in governance, including the establishment of a military junta. Such actions can result in widespread unrest and international condemnation, affecting the country's stability and relations with other nations.
