National WWI Museum and Memorial, a publicly owned institution headquartered in the US, was founded in 1921. Operating with approximately 60 employees, it reported $8.6M in revenue as of 2024. The museum, located in Kansas City, Missouri, United States, originally opened in 1926 as the Liberty Memorial. It was designated by the United States Congress in 2004 as the country's official museum dedicated to World War I, with Congress adding the designation as the country's official war memorial in 2014 as part of the Centennial recognition. A non-profit organization manages it in cooperation with the Kansas City Board of Parks and Recreation Commissioners. The museum focuses on global events from the causes of World War I before 1914 through the 1918 armistice and 1919 Paris Peace Conference. Visitors enter the exhibit space within the 32,000-square-foot (3,000 m2) facility across a glass bridge above a field of 9,000 red poppies, each representing 1,000 combatant deaths.
