Explanation:

The Treaty of Versailles is the treaty that officially brought down the facts of the First World War. The treaty was signed after six months of negotiations after the Paris Peace Conference in 1919. The victorious Allies in World War I signed separate agreements with the losing central powers of war (the German Empire, the Austro-Hungarian Empire, the Ottoman Empire and Bulgaria). The agreements were signed on June 28, 1919. The treaty was later amended on 10 January 1920 to include the German recognition of war responsibility and Germany must compensate the financially affected parties. It was called the Treaty of Versailles following the geographical location in which the treaty was signed - the French palace of Versailles.
