Gunn Memorial Library in Washington will present a lecture to mark the 100th anniversary of the assassination of Archduke Franz Ferdinand of the Austrian Empire June 28.

Michael Nolan, a professor of European history at Western Connecticut State University in Danbury, will lead the program beginning at 11 a.m. at the Wykeham Road library.

Nolan will discuss the contentious years leading up to the assassination, how the events of that day unfolded, the impact the resulting World War I had on the 20th century, and who was really to blame for the origins of the war, the answer to which is not as clear cut as many might think and has vexed historians for the past century.

The historical society and museum's exhibit, "Over There: Washington and The Great War," will be open for viewing at the museum next door during the lecture.
