The major Allied powers<span> in World War I were </span>Great Britain<span> (and the</span>British Empire<span>), </span>France<span>, and the </span>Russian Empire<span>, formally linked by the </span>Treaty of London<span> of September 5, 1914. Other countries that had been, or came to be, allied by treaty to one or more of those powers were also called Allies: Portugal and Japan by treaty with Britain; Italy by the </span>Treaty of London<span> of April 26, 1915, with all three powers. Other countries—including the </span>United States<span> after its entry on April 6, 1917—that were arrayed against the Central Powers were called “Associated Powers,” not Allied powers; U.S. President </span>Woodrow Wilson<span> emphasized that distinction to preserve America’s free hand. The </span>Treaty of Versailles<span> (June 28, 1919) concluding the war listed 27 “Allied and Associated Powers”: </span>Belgium<span>, </span>Bolivia<span>, </span>Brazil<span>, the British Empire, </span>China<span>, </span>Cuba<span>, </span>Czechoslovakia<span>, </span>Ecuador<span>, France, </span>Greece,Guatemala<span>, </span>Haiti<span>, the </span>Hejaz<span>, </span>Honduras<span>, Italy, Japan, </span>Liberia,Nicaragua<span>, </span>Panama<span>, </span>Peru<span>, </span>Poland<span>, </span>Portugal<span>, </span>Romania<span>, </span>Serb-Croat-Slovene State<span>, </span>Siam<span>, the United States, and </span>Uruguay<span>.</span>

Allied forces faced all type of challenges during the world war two, from food to ammo. Every supplies that the allied forces needed at that time of war should have to cross the pacific oceans which were subjected to the difficulties of German's frequent attacks, climate of pacific ocean and distance that to be crossed.
German war planes gave a tough card to the supply ships of allied forces and the supplies failed to reach the troops on time. This situation increased the demand over supplies during the World War II.
The main factor that contributed to Britain establishing colonies in the Pacific islands is that "A British captain explored the Pacific Islands."
This is evident in the fact that a British explorer or navigator known as James Cook explored the uncharted territory covering the Pacific Islands from the area of New Zealand to Hawaii around 1768 to 1779. His exploration knowledge led the Europeans particularly Britain to establish colonies in the region.
