Final answer:
World War I dominated Woodrow Wilson's second term and ended the Progressive Movement.
Step-by-step explanation:
The event that came to dominate the second term of Woodrow Wilson and eventually ended the period known as the Progressive Movement was World War I.
While Wilson initially tried to avoid getting involved in the war, he eventually led the United States in declaring war on Germany, which shifted the focus of the country towards the war effort and away from progressive reforms.
The war brought about a change in priorities, with national security and international intervention taking precedence over the goals of the Progressive Era.
