The Portuguese Expeditionary Corps (CEP, Portuguese: Corpo Expedicionário Português) was the main expeditionary force from Portugal that fought in the Western Front, during World War I. Portuguese neutrality ended in 1916 after the Portuguese seizure of German merchant ships resulted in the German Empire declaring war on Portugal. The expeditionary force was raised soon after and included around 55,000 soldiers.
