The Eastern Front of World War I was characterized by vast open spaces and shifting borders, while the Western Front was defined by a static and heavily fortified line stretching from the English Channel to the Swiss border. Strategies on the Eastern Front focused on mobility and maneuver warfare, with Russian and German forces engaging in large-scale offensives and retreats. On the Western Front, a strategy of trench warfare prevailed, with both sides heavily entrenched and engaged in costly battles for small gains in territory.
