what was one cause of the united states involvement in world war 1
American entry into World War I In 1917, with Russia experiencing political upheaval following widespread disillusionment there over the war, and with Britain and France low on credit, Germany appeared to have the upper hand in Europe,[3] while Germany's ally, the Ottoman Empire, clung stubbornly to its possessions in the Middle East. In the same year, Germany decided to resume unrestricted submarine warfare against any vessel approaching British waters; this attempt to starve Britain into surrender was balanced against the knowledge that it would almost certainly bring the United States into the war. Germany also made a secret offer to help Mexico regain territories lost in the Mexican–American War in an encoded telegram known as the Zimmermann Telegram, which was intercepted by British Intelligence. Publication of that communique outraged Americans just as German U-boats started sinking American merchant ships in the North Atlantic. Wilson then asked Congress for "a war to end all wars" that would "make the world safe for democracy", and Congress voted to declare war on Germany on April 6, 1917.[4]
American Revolution Interpretations vary concerning the effect of the Revolution. Veterans who fought in the war referred to it as "the revolution",[175][176] although the war is sometimes known as the "American War of Independence" outside the United States, particularly in the United Kingdom.
History of the United States Armed conflict began in 1775 as Patriots drove the royal officials out of every colony and assembled in mass meetings and conventions. In 1776, the Second Continental Congress declared that there was a new, independent nation, the United States of America, not just a collection of disparate colonies. With large-scale military and financial support from France and the military leadership of General George Washington, the American Patriots won the Revolutionary War. The peace treaty of 1783 gave the new nation the land east of the Mississippi River (except Florida and Canada). The central government established by the Articles of Confederation proved ineffectual at providing stability, as it had no authority to collect taxes and had no executive officer. Congress called a convention to meet secretly in Philadelphia in 1787. It wrote a new Constitution, which was adopted in 1789. In 1791, a Bill of Rights was added to guarantee inalienable rights. With Washington as the first president and Alexander Hamilton his chief political and financial adviser, a strong central government was created. When Thomas Jefferson became president he purchased the Louisiana Territory from France, doubling the size of the United States. A second and final war with Britain was fought in 1812.
World War I The trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a diplomatic crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia[12][13] and, as a result, entangled international alliances formed over the previous decades were invoked. Within weeks the major powers were at war, and the conflict soon spread around the world.
