Concept note-1: -Also known as the Locarno Pact, the treaty guaranteed Germany’s western frontier, which the bordering states of France, Germany, and Belgium pledged to treat as inviolable. As signatories of the agreement, Britain and Italy committed themselves to help to repel any armed aggression across the frontier.
Concept note-2: -The Locarno Pact had three main aims: To secure borders of the nations of Europe after the First World War. Germany agreed to the border with France, and as a result France agreed that they would be in a state of peace with Germany. To ensure the permanent demilitarisation of the Rhineland.
Concept note-3: -The treaties were initialed at Locarno, Switz., on October 16 and signed in London on December 1.
Concept note-4: -The principal treaty concluded at Locarno was the Rhineland Pact between Germany, France, Belgium, the United Kingdom, and Italy. Germany formally recognised its new western borders as established by the Treaty of Versailles.
Concept note-5: -Stresemann accepted Germany’s western (not eastern) borders. All countries decided to renounce the use of invasion and force, except in self-defence. The Pact reassured France about its borders and Germany about any French invasion/occupation, as had happened in 1923.
