Lech Walesa is probably the most famous of all the thousands — actually millions — who struggled against the oppression of Communist rule in Eastern Europe and the Soviet Union. The only person with a similar level of fame is Vaclav Havel in what was then Czechoslovakia. Walesa was the leader of the Solidarity trade union which, according to the legend, grew from ten members to ten million in a single year, fundamentally challenging the totalitarian rule of the Communist party.
