Ottoman/Russian Balance of Power.
(There were a number of causes for the Crimean War. None of them particularly good. A conflict between Catholic and Orthodox Christians concerning access to the Holy places in Palestine was one. Arguably this was about Ottoman treatment of Orthodox Christians in Ottoman territory which was a concern to Russia. Inept negotiation made the situation worse.
The major players were Britain, France, and Turkey on one side and Russia on the other. Austria played an important diplomatic role. A since extinct country of Piedmont/Sardinia also sent troops.
Russia lost but the bungling on both sides made the war a gong show from the beginning. Arguably the the issues at stake had been decided before the Crimean portion of the conflict even started. The War was by then pointless homicidal idiocy.
It was an important precursor in the next balance of power moves that created Italy and Germany.)
The territorial acquisition that was a result of a rebellion supported by the US military was Hawaii. Hawaii became a state in 1959. It had been an American territory with partial independence before that. Followinf several rebellions in this territory, Hawaii finally became the 50th American state in 1959, being America's most recent state to join the United States of America.
American people wanted to annex Hawaii, and the US Military supported. However, they were not aware that the people of Hawaii were not willing to be annexed, and neither was the sovereign ruler of Hawaii.
