Before World War II, what is now known as World War I was referred to by various names, including The Great War, The World War, The Kaiser’s War, The War of the Nations, The War in Europe, or The European War. In the United Kingdom and the United States, it was often called “The war to end all wars.” In France and Belgium, it was sometimes described as La Guerre du Droit (the War for Justice) or La Guerre Pour la Civilisation/de Oorlog tot de Beschaving (the War to Preserve Civilization), particularly on medals and commemorative monuments. In Britain and Canada, official histories of the conflict typically use the term “First World War,” while American accounts usually refer to it as “World War I.”
World War I was a military conflict primarily centered in Europe, beginning in the summer of 1914 and concluding in late 1918. The war involved nearly all of the world’s major powers, divided into two opposing alliances: the Allies (led by the Triple Entente) and the Central Powers. Over 70 million military personnel, including 60 million Europeans, were mobilized in what became one of the largest wars in history. More than 9 million combatants lost their lives, largely due to advancements in firepower outpacing improvements in mobility, making it the second deadliest conflict in history.
The United States formally entered World War I on April 6, 1917, after initially maintaining a position of neutrality while supplying the United Kingdom and other Allied nations. During its involvement, the U.S. mobilized over 4 million military personnel, suffering more than 300,000 casualties, including over 110,000 deaths. The war prompted a significant expansion of the U.S. government to manage the war effort and saw a substantial increase in the size and role of the U.S. military.

Dear Access Genealogy,
How and where can I find the date(s) of when civilians could enlist for WWI in Paterson, New Jersey? My great grandfather’s last name was Mac Lean. At times, he even spelled his last name as Maclean.
