 It began at Stralsund on the Baltic Sea (in German Sources "East Sea") coast, and crossed the territory of East Germany, taking a far from direct route, to end, officially, at Dresden.It was considered remarkable because members of East German political opposition groups were permitted to participate in the march legally.The march was named to honour the former prime minister of Sweden, Olof Palme, who had been shot dead by an unidentified assailant on a Stockholm street the previous year, on 28 February 1986.
