Most of the rest of the world was classified in a more planned top-down manner. Europe had too many locations for only one starting letter, so it was split into Exxx for northern Europe and Lxxx for southern Europe. The second letter was more specific: EGxx was the United Kingdom (G for Great Britain), EDxx was West Germany (D for Deutschland), ETxx was East Germany (the ETxx code was reassigned to military fields after the reunification), ECxx was Czechoslovakia (C for Československo; the code was dropped following the breakup and was split into two new ICAO codes: LKxx for the Czech Republic and LZxx for Slovakia), LExx was Spain (E for España), LAxx was Albania, LYxx was Socialist Yugoslavia (the codes were split into several republics when the country was broke up in the early 1990s; e.g. Croatia's new ICAO code LDxx (derived from D for Dalmatia) following that country's independence; thus LYxx retained the code for the republics of Serbia and Montenegro) and so on. France was designated LFxx, as the counterpart EFxx was unambiguously Finland (originally OFxx, as the more rigid geographical structure evolved over time; in the beginning, countries usually had "blocks" of codes; for example, Finland still has the country identifier OH- in its aircraft registrations). Thus Uxxx referred to the Soviet Union with the second letter denoting the specific region within it, and so forth. Following the fall of the Soviet Union, such as those, republics Estonia, Latvia and Lithuania created ICAO codes EExx, EVxx and EYxx, respectively, Moldova, another former Soviet republic, created a LUxx ICAO code inline with neighboring Romania (currently assigning the LRxx code), while the other republics retained the Uxxx code.
