As of 1991, Czechoslovakia had a population of 15.6 million, of which by ethnicity 62.8% were Czechs (including Moravians), 31% Slovaks, 3.8% Hungarians, 0.7% Roma,[1] and 0.4% Silesians.
Smaller groups of Rusyns, Ukrainians, Germans, Austrians, Poles and Jews (the post-Holocaust community) combined made up the remaining 1.6% of the population.
[citation needed] Following the expulsion of the ethnic German population from Czechoslovakia, parts of the former Sudetenland, especially around Krnov and the surrounding villages of the Jesenik mountain region in northeastern Czechoslovakia, were settled in 1949 by Communist refugees from Northern Greece who had left their homeland as a result of the Greek Civil War.
Although the country's ethnic composition had been simplified, the division between Czechs and Slovaks remained; each group had a very similar history, but sometimes divergent aspirations.
