A stronghold is a fortified place designed to protect and defend against attacks. Historically, strongholds were often castles or military fortifications built in strategic locations. They served as safe havens for troops and civilians during conflicts, providing shelter and resources. In modern contexts, the term "stronghold" can also refer to areas where a particular group or ideology has significant influence or control. For example, a city might be considered a political stronghold if it consistently supports a specific party or candidate during elections. Strongholds can be physical or metaphorical, representing security and dominance.
