Today’s Walking Classroom looks at America’s national anthem, “The Star-Spangled Banner” and the historical battle that inspired its lyrics. “The Star-Spangled Banner” was originally written as a poem after a battle in the War of 1812, when Francis Scott Key saw the flag flying over Fort McHenry and he knew that the British had failed in their attack. The song is often sung at sporting events and other special occasions that allow us to celebrate our country and show our pride in America.
