Which treaty formally ended the First World War with Germany?

The Treaty of Versailles formally ended the First World War with Germany.

The treaty was signed on 28 June 1919 in the Hall of Mirrors at the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand. It came into force on 10 January 1920 and established the main peace terms between Germany and the Allied powers.

Germany lost territory, accepted military restrictions, and was required to make reparations. Article 231, commonly called the war guilt clause, assigned responsibility for the war’s losses and damage in the treaty’s legal framework.

The Treaty of Versailles was one of several Paris Peace Conference agreements. The Treaty of Saint-Germain dealt with Austria, while the Treaty of Trianon concerned Hungary. The treaty’s harsh and controversial terms later became part of the political background to the rise of Adolf Hitler, though historians debate the weight of different causes.
