 In part because of the problems created by collectivisation, agriculture was largely de-collectivised in Poland in 1957.The fact that Poland nevertheless managed to carry out large-scale centrally planned industrialisation with no more difficulty than its collectivised Eastern Bloc neighbours further called into question the need for collectivisation in such planned economies.Only Poland's "western territories", those eastwardly adjacent to the Oder-Neisse line that were annexed from Germany, were substantially collectivised, largely in order to settle large numbers of Poles on good farmland which had been taken from German farmers.
