Summarize the main points made in the following article about the history and legacy of the Berlin Wall:

The Berlin Wall was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Its construction was initiated by the German Democratic Republic (East Germany) to prevent mass emigration to the West. It stood as an iconic symbol of the Iron Curtain - the ideological divide between Soviet-controlled Eastern Europe and the capitalist Western nations during the Cold War.

The Wall sliced right through the heart of Berlin, separating families, lovers, and communities virtually overnight. Over 28 miles long and 12 feet high, it formed a heavily militarized border between democratic, capitalist West Berlin and communist East Berlin. Guards were authorized to shoot anyone attempting to flee over the Wall.

The Berlin Wall was a tragic legacy of the Cold War's oppression and mistrust, but its fall on November 9, 1989 became a powerful symbol of peace and unity as ecstatic crowds tore it down with hammers and chisels. Germany was soon reunified, and the Wall's demolition paved the way for the end of the Soviet empire in Eastern Europe. Today preserved fragments stand as powerful monuments to freedom's victory over division and totalitarianism.

Hans Niemann is launching a counterattack in his dispute with chess world champion Magnus Carlsen, filing a federal lawsuit that accuses Carlsen of maliciously colluding with others to defame the 19-year-old grandmaster and ruin his career.

It's the latest move in a scandal that has injected unprecedented levels of drama into the world of elite chess since early September, when Carlsen suggested Niemann's upset victory over him at the Sinquefield Cup tournament in St. Louis was the result of cheating.

Niemann wants a federal court in Missouri's eastern district to award him at least $100 million in damages. Defendants in the lawsuit include Carlsen, his company Play Magnus Group, the online platform Chess.com and its leader, Danny Rensch, along with grandmaster Hikaru Nakamura.

The lawsuit says that in the aftermath of Niemann's upset win in September, Carlsen has been motivated to preserve his status as the "king of chess" so he could complete his company's buyout by Chess.com — a deal worth tens of millions of dollars.

The court filing accuses Rensch and Nakamura of using their influence to amplify and bolster Carlsen's claims that Niemann is a cheater. The suit seeking a jury trial was filed on Thursday, one day after Niemann finished the U.S. Chess Championship tournament in a five-way tie for fifth place.
