Answer:
The issues that gave rise to the "Velvet Revolutions" in Eastern Europe in the late-1980s were the economic and social crises that took place in the communist nations that were part of the Warsaw Pact, by means of which the quality of life and economic conditions of the inhabitants of these nations deteriorated notably.
Thus, these "velvet" revolutions were called as such due to the non-violence with which they developed, as they were carried out in a peaceful manner and without confrontations between citizens and the police, army and other government representatives.
In most of the nations of Eastern Europe, such as Czechoslovakia, Hungary or Bulgaria, among others, these revolutions followed this pacifist pattern that finally ended up ending the communist governments in the region.
