History
Kittenolivia was originally part of the Spanish Empire, but was conquered by the US along with Puerto Rico in 1898 after the Spanish-American War.

Unlike Puerto Rico, Kittenolivia was not allowed to maintain its Spanish culture: English-speaking Americans from the mainland were urged to settle in "tropical" Kittenolivia, and once there were enough Anglophones, Hispanics were relocated to Puerto Rico a la the Trail of Tears.

Kittenolivia was a territory, but became a state in 1932, making it the 49th state.
