On Thursday, April 13 LancasterHistory.org will host Dr. Carl Strikwerda to observe the 100-year anniversary of the United States’ involvement in World War I with the colloquium 100 Years: US Entry into World War I. The entry of the United States into World War I in April 1917 changed both American and world history. For the first time, the US became deeply involved in international politics as a military and economic power. Join Dr. Carl Strikwerda as he explores why the US entered The Great War, the national and global impact of our involvement, and how we can use those experiences to inform our nation’s future military decisions. Dr. Carl J. Strikwerda is the fourteenth president of Elizabethtown College, serving since 2011, and previously served as Dean of the Faculty of Arts and Sciences at the College of William and Mary. He has served as a historical consultant to the National World War I Museum in Kansas City, Missouri, and to several colleges and universities on higher education administration. He has lectured to business groups, schools and religious organizations on World War I and the history of globalization. The colloquium 100 Years: US Entry into World War I will take place on Thursday, April 13, 2017 in Ryder Hall at LancasterHistory.org, 230 N President Avenue, Lancaster. A speaker’s reception with refreshments will begin at 4pm, followed by the lecture from 4:30-5:30pm. This event is free and open to the public.
