The French Maginot Line was a defensive fortification built by France along its eastern border with Germany after World War I. Constructed between the 1920s and 1930s, it aimed to protect France from potential invasions. The line consisted of bunkers, fortresses, and various military installations designed to withstand attacks. Despite its extensive construction, the Maginot Line was ultimately bypassed during World War II when German forces invaded France through Belgium. This strategic oversight highlighted the limitations of static defenses, leading to significant changes in military tactics and strategies in the years that followed.
