The correct answer is "was heavily involved."
During World War I, Georgia was heavily involved.
However, let us first say that at the beginning of the war the state of Georgia remained neutral, as had been the foreign policy of President Woodrow Wilson.
Indeed, some people and journalists in the state of Georgia were against the US entering World War I. Nevertheless, after some time, things changed and Georgia became an important state for the US war effort.
The US federal government built many military facilities, installations, and training camps for the US soldiers. People from Georgia worked very hard to help the government, the US Army, and the Navy during the war.
