The historical context

The Franco-Belgian occupation of the Ruhr caused a serious economic crisis in Germany in 1923.

Following the German defeat in the First World War (1914-1918), The governments of the victorious countries imposed a series of conditions on Germany by signing the Treaty of Versailles in 1919.

The territorial clauses of the Treaty of Versailles meant that Germany lost 13% of its territory. The military clauses led to a sharp reduction in Germany’s armament and troops, as well as the demilitarisation of the Rhineland (a region bordering France, Belgium, Luxembourg and the Netherlands) and the Allied occupation of the western part of that region.

These clauses were added to war reparations, that is, the expensive economic compensation that Germany had to pay to the victorious countries. Germany’s problems in meeting war reparations led to the French and Belgian occupation of the German Ruhr region in 1923.This caused a major economic crisis in Germany. The United States and the United Kingdom put pressure on the French and German governments to negotiate.

In 1924, the parties involved agreed to the Dawes Plan, drawn up by a commission chaired by the American financier Charles Dawes, which facilitated Germany’s payment of reparations. This situation of economic harmony was related to A new era of political cooperation which was reflected in the signing of the Locarno Treaties in 1925.

What were the agreements of the Locarno Treaties?

The negotiations that led to the signing of the Locarno Treaties began when German Foreign Minister Gustav Stresemann proposed to his French counterpart Aristide Briand that they discuss the issue of legal recognition of Germany’s western borders.

In October 1925, Stresemann and Briand met in the Swiss city of Locarno together with the foreign ministers of Belgium (Émile Vandervelde) and the United Kingdom (Austen Chamberlain). The President of the Council of Ministers of Italy, Benito Mussolini, also took part in the meetings. The Locarno Treaties were signed on 1 December 1925 in London.

The agreements signed were as follows:

  • A treaty of mutual guarantee concerning Germany’s borders with France and Belgium (signed by Germany, France and Belgium, with the United Kingdom and Italy as guarantors).
  • An arbitration treaty between Germany and Belgium, and another between Germany and France.
  • An arbitration treaty between Germany and Poland, and another between Germany and Czechoslovakia.
  • A treaty of mutual assistance between France and Poland, and another between France and Czechoslovakia, in case of a German attack.

The Treaty of Mutual Guarantee of Germany’s Borders with France and Belgium was the main agreement signed. It established the following:

  • That Germany’s western borders, with France and Belgium, were inviolable.
  • That France, Belgium and Germany would never attack each other except in case of legitimate defence or as a consequence of an obligation of the League of Nations.
  • That they would resolve their disputes by peaceful means.
  • That, in the event that any of the signatories broke these agreements, the other signatories would come to the aid of the attacked party in accordance with the agreement of the League of Nations.

The treaties between France, Czechoslovakia and Poland provided for mutual assistance in the event of an unprovoked attack.

Consequences of the Locarno Treaties

The Locarno Treaties initiated a period of cooperation that ended when Hitler came to power in Germany.

As an indirect result of the Locarno Treaties, Germany joined the League of Nations on 8 September 1926 and the Allies evacuated the Rhineland in 1930.five years ahead of the schedule provided for in the Treaty of Versailles.

However, the great problem with the Locarno Treaties was that neither Stresemann nor No subsequent German government recognized Germany’s eastern borders.The Treaty of Mutual Guarantee applied to the western borders, while the eastern borders were subject only to an arbitration agreement. It was precisely in the east that the Second World War ultimately originated.

The Locarno Treaties were definitively annulled by Adolf Hitler when, shortly after coming to power in Germany, he pushed for the remilitarization of the Rhineland in 1936. Hitler subsequently breached the arbitration agreement with Czechoslovakia and Poland and invaded both countries. The invasion of Poland sparked the start of World War II.
