Spanish-American War — loss of the residual empire
Who & why: after the loss of mainland Latin America, Spain retains Cuba, Puerto Rico, and the Philippines as its residual overseas empire through the 19th century. Rising Cuban and Filipino independence movements, and the explosion of the USS Maine in Havana harbor in February 1898, bring the United States into a brief but decisive war. The December 1898 Treaty of Paris strips Spain of Cuba (made a US protectorate, then independent), Puerto Rico, Guam, and the Philippines, effectively ending the Spanish Empire as a global power in a matter of months.
What it represents: Wikipedia, Flags of the World and the U.S. National Park Service agree that the red-yellow-red flag with the crowned arms, not the Cross of Burgundy, was Spain's war ensign from 1785 and its state and war flag from the Royal Decree of 13 October 1843. The Cross of Burgundy drawn here is therefore not confirmed as the flag of 1898.
Wikipedia and FOTW: a Royal Decree of 13 October 1843 made the red-yellow-red flag the State and war flag and ensign. FOTW (War Ensign 1785-1931): the red-yellow-red flag with the crowned arms was the war ensign from 1785 and the state flag from 1843; the page notes a 1899 depiction. The U.S. National Park Service says the red-and-gold ensign replaced the Burgundian cross at sea in 1785 and as regimental colours in 1843.

Not established: Three sources agree that the red-yellow-red flag, not the Cross of Burgundy, was Spain's state and war flag in 1898, so the page's drawing is contradicted and should be replaced; no source read says the cross flew in the Spanish-American War.
