when did the us declare war on spain
Spanish–American War President McKinley signed a joint Congressional resolution demanding Spanish withdrawal and authorizing the President to use military force to help Cuba gain independence on April 20, 1898.[17] In response, Spain severed diplomatic relations with the United States on April 21. On the same day, the US Navy began a blockade of Cuba.[18] On April 23, Spain stated that it would declare war if the US forces invaded its territory. On April 25, Congress declared that a state of war between the US and Spain and had de facto existed since April 21, the day the blockade of Cuba had begun.[19] The United States sent an ultimatum to Spain demanding that it surrender control of Cuba, but due to Spain not replying soon enough, the United States assumed Spain had ignored the ultimatum and continued to occupy Cuba.[20][not in citation given]
Spain during World War I Spain remained neutral throughout World War I between 28 July 1914 and 11 November 1918, and despite domestic economic difficulties,[1] it was considered "one of the most important neutral countries in Europe by 1915".[2] Spain had enjoyed neutrality during the political difficulties of pre-war Europe, and continued its neutrality after the war until the Spanish Civil War began in 1936.[2] While there was no direct military involvement in the war, German forces were interned in Spanish Guinea in late 1915.
