Answer:
Assuming you are referring to the conferences that took place during World War I, there were several important conferences that took place between the European powers during this time.
One of the most significant was the Paris Peace Conference of 1919, which was held after the end of World War I to negotiate the terms of the peace settlement. The conference was attended by representatives of the victorious Allied powers, including France, Britain, Italy, and the United States, as well as representatives of defeated Germany and other Central Powers. The terms of the peace settlement, which were outlined in the Treaty of Versailles, included provisions for disarmament, the establishment of the League of Nations, and the imposition of heavy reparations on Germany. The treaty also redrew the map of Europe, creating new states and redefining the borders of existing ones.
Other important conferences during World War I included the Algeciras Conference of 1906, which sought to resolve disputes between France and Germany over the control of Morocco, and the Treaty of London of 1915, which promised Italy territorial gains in exchange for its entry into the war on the side of the Allies. These conferences and treaties played a significant role in shaping the political and territorial landscape of Europe in the early 20th century.
