Lee Kuan was a noted Human historical political despot on Earth during the early-to-mid 21st Century, who ultimately failed at his goals of conquest and absolute power. The book Federation: The First 150 Years gives the spelling of Kuan's family name as "Le". American forces destroyed the ECON's governing palace, killing Lee, in 2053. (ST reference: Federation: The First 150 Years) Spock mentioned Lee along with Ramses II, Julius Caesar, Alexander, Napoléon Bonaparte, and Adolf Hitler to show that Earth history is full of men seeking absolute power. (TOS episode: "Patterns of Force")
