Insular Government of the Philippine Islands in the context of "Insular Government of Porto Rico"

The Allies or the Entente (UK: /ɒ̃ˈtɒ̃t/, US: /ɒnˈtɒnt/ on-TONT) was an international military coalition of countries led by the French Republic, the United Kingdom, the Russian Empire, the United States, the Kingdom of Italy, and the Empire of Japan against the Central Powers of the German Empire, Austria-Hungary, the Ottoman Empire, and the Kingdom of Bulgaria in World War I (1914–1918).

By the end of the first decade of the 20th century, the major European powers were divided between the Triple Entente and the Triple Alliance. The Triple Entente was made up of the United Kingdom, France, and Russia. The Triple Alliance was originally composed of Germany, Austria–Hungary, and Italy, but Italy remained neutral in 1914. As the war progressed, each coalition added new members. Japan joined the Entente in 1914 and, despite proclaiming its neutrality at the beginning of the war, Italy also joined the Entente in 1915. The term "Allies" became more widely used than "Entente", although the United Kingdom, France, Russia, and Italy were also referred to as the Quadruple Entente and, together with Japan, as the Quintuple Entente. The five British Dominions (Australia, Canada, New Zealand, Newfoundland, and the Union of South Africa) all fought alongside the British. The colonies of Allied countries, such as the American Philippines, Belgian Congo, British India, French Algeria, and Japanese Korea, were also used as a source of manpower by the colonial powers.

The Commonwealth of the Philippines (Spanish: Mancomunidad de Filipinas; Tagalog: Komonwelt ng Pilipinas) was an unincorporated territory and commonwealth (dependency) of the United States that existed from 1935 to 1946. It was established following the Tydings–McDuffie Act to replace the Insular Government of the Philippine Islands and was designed as a transitional administration in preparation for full Philippine independence. Its foreign affairs remained managed by the United States.

During its more than a decade of existence, the Commonwealth had a strong executive and a supreme court. Its legislature, dominated by the Nacionalista Party, was initially unicameral but later bicameral. In 1937, the government selected Tagalog – the language of the capital Manila and its surrounding provinces – as the basis of the national language, although it would be many years before its usage became general. Women's suffrage was adopted, and the economy recovered to pre-Depression levels before the Japanese invasion of the islands in 1941. A period of exile took place during World War II from 1942 to 1945, when Japan occupied the Commonwealth.
