I said so
To cut-off the flow of oil and fuel to the Axis powers. :)
first of all the U.S didn't join anyone the allies powers joined them.
The Battle of Marne was the first major War World I victory for the Allied Powers. The Allies successfully saved Paris and France remained in the war.
Answer Italy on 8 September 1943 Italy overthrew dictator Benito Mussolini in July and tried to negotiate with the Allies to join them as an ally. The Allies would only agree to an unconditional surrender. The surrender was announced when it was learned troop ships were headed to Italy.
The Allies built the first trenches during World War I, primarily in response to the static nature of the conflict and the need for defensive positions. The trench warfare that characterized the Western Front emerged as both sides quickly adapted to the challenges of modern warfare. However, it was the Allies, particularly the French and British, who initially developed extensive trench systems early in the war. The Central Powers later established their own trench networks in response.
During the First World War, Britain was allied with several countries, primarily forming the Triple Entente with France and Russia. Other key allies included Italy, which joined the Allies in 1915, and the United States, which entered the war in 1917. Additionally, countries such as Belgium, Serbia, Japan, and Greece also supported the Allied Powers. Together, these nations worked against the Central Powers, primarily Germany, Austria-Hungary, and the Ottoman Empire.
phoney war, because little action was happening between the allies and axis powers
first we will start with the axis. there were the Nazis, Italians (they dropped out of the war in 1943), and japanese. the allies had the US, Canada, britain, and most of the other countries in europe.
Russia supported Serbia first, then when Germany entered the war (on the side of Austria-Hungary--the Central Powers), France and Britain joined in as well (on the side of Serbia--The Allies). Bulgaria joined in later (Central Powers), as did Italy (Allies). As it became truly a world war, Japan and the United States joined (part of the Allies), and so did the Ottoman Empire (Central Powers), and several other countries such as Portugal, Romania, etc. on the Allied side.
Germany was the first country to use poison gas
Both. However, it was never really an Axis-power, despite the fact that it maintained basically an 'I will help you' pact with the Axis-powers. It later went to the allies' side when Hitler betrayed and invaded the USSR.
The first formal agreement in World War I was the Treaty of London, signed in 1915 between Italy and the Allies, which included France, the United Kingdom, and Russia. Italy agreed to join the Allies in exchange for territorial gains. This marked Italy's entry into the war against the Central Powers.
