The stalemate during World War I, particularly on the Western Front, lasted for several years, roughly from late 1914 until early 1918. This period was characterized by trench warfare, where neither side could gain a decisive advantage, leading to high casualties and limited territorial changes. The stalemate was eventually broken by coordinated offensives and the introduction of new tactics and technology, culminating in the end of the war in November 1918.
The stalemate generally refers to the Trench warfare in France 1915-1918.
