Czech Silesia
Moravian ethnicity was declared for the first time in the population census of 1991. After the Velvet Revolution a strong political movement to reinstate the Moravian-Silesian land ("země Moravskoslezská" in Czech, having been one of the four lands of Czechoslovakia between 1928 and 1939) was active in Moravia. Accordingly, the so far officially united Czech ethnicity was split in line with the historical division of the Czech Republic into Bohemia, Moravia and Czech Silesia (the "Czech lands"). Part of the Czech speaking inhabitants of Moravia declared Moravian ethnicity and part of the Czech speaking inhabitants of Czech Silesia declared Silesian ethnicity.
