 Growing industrialism, partly spurred on by the war, created a new culture of competition and materialism.In 1869, Boston was the site of the National Peace Jubilee, a massive gala to honor veterans and to celebrate the return of peace.Conceived by composer Patrick Gilmore, who had served in an army band, the celebration was held in a colossal arena in Boston's Back Bay neighborhood designed to hold 100,000 attendees and specifically built for the occasion.
