The Night of the Long Knives (German:    ), also called Operation Hummingbird (German: "Unternehmen Kolibri") or, in Germany, the Röhm Putsch (German spelling: "Röhm-Putsch" ), was a purge that took place in Nazi Germany from June 30 to July 2, 1934, when the Nazi regime carried out a series of political extrajudicial executions intended to consolidate Hitler's absolute hold on power in Germany.
 Many of those killed were leaders of the "Sturmabteilung" (SA), the Nazis' own paramilitary organization, colloquially known as the "Brownshirts" due to the color of their uniforms.
 The best-known victim of the purge was Ernst Röhm, the SA's leader and one of Hitler's longtime supporters and allies.
 Leading members of the left-wing Strasserist faction of the Nazi Party (NSDAP), along with its figurehead, Gregor Strasser, were also killed, as were establishment conservatives and anti-Nazis, such as former Chancellor Kurt von Schleicher and Bavarian politician Gustav Ritter von Kahr, who had suppressed Adolf Hitler's Munich Beer Hall Putsch in 1923.
 The murders of SA leaders were also intended to improve the image of the Hitler government with a German public that was increasingly critical of thuggish Brownshirt tactics.
The Battle of Nuremberg was a five-day battle between the forces of the United States 7th Army on one side, and Nazi Germany and Russian Liberation Army volunteers on the other during World War II.
 The battle saw some of the fiercest urban combat during the war and it took four days for the United States to capture the city.
 The battle was a blow to Nazi Germany as Nuremberg was a center of the Nazi regime.
 Many rallies took place in the city and to lose the city to the Americans took a heavy toll on already low German morale.
 Even though American forces heavily outnumbered the German forces, it wasn't until 20 April, that the 7th Army took the city center.
 The battle devastated the city.
