Trench warfare began in the 17th century by the French. It was more widely used in WW I. The opposing sides would dig trenches in order to fight and hide from the opponent. With the invention of the machine gun they also provided protection from this deadly weapon. There was an area between known as no man's land that divided the two trenches. Often you would find barbed wire to protect the enemy from entering each others trenches.
