What was the purpose of the Maginot Line built by France in 1933?

The Maginot Line was constructed by France primarily as a strong defensive measure to protect its eastern border against the threat of German aggression following the experiences of World War I. Named after André Maginot, who was a member of the French parliament and a strong advocate for fortifications, the line consisted of a series of fortifications, bunkers, and obstacles designed to deter or slow down any German invasion.

The decision to focus on the eastern border was based on the belief that Germany remained the primary threat to France's national security — particularly after the devastation of World War I. France aimed to create a formidable defense that would compel any invading army to engage heavily fortified positions, buying time for French forces to mobilize and respond.

While some might think that a defensive pact with neighboring countries or fortifications along the western border were priorities, the immediate historical context and military strategy of the interwar period highlighted the perception of Germany as a direct threat. This justification solidified the focus on securing the eastern frontier with the Maginot Line, making it a significant aspect of French military policy during the period leading up to World War II.
