Berthold Alfred Maria Schenk Graf von Stauffenberg (15 March 1905, Stuttgart – 10 August 1944, Berlin-Plötzensee) was a German aristocrat and lawyer who was a key conspirator in the plot to assassinate Adolf Hitler on 20 July 1944, alongside his younger brother, Colonel Claus Schenk Graf von Stauffenberg.
 After the plot failed, Berthold was tried and executed by the Nazi regime.
The "Führer" Headquarters ("Führerhauptquartiere" in German), abbreviated FHQ, is a common name for a number of official headquarters used by the Nazi leader Adolf Hitler and various German commanders and officials throughout Europe during the Second World War.
 Perhaps the most widely known headquarters was the "Führerbunker" in Berlin, Germany, where Hitler committed suicide on 30 April 1945.
 Other notable headquarters are the "Wolfsschanze" (Wolf's Lair) in East Prussia, where Claus von Stauffenberg in league with other conspirators attempted to assassinate Hitler on 20 July 1944, and Hitler's private home, the "Berghof", at Obersalzberg near Berchtesgaden, where he frequently met with prominent foreign and domestic officials.
The Plot to Assassinate Hitler (German: Der 20.
 Juli) is a German feature film produced by CCC Film on the failed 20 July 1944 attempt to assassinate Adolf Hitler.
 Falk Harnack directed and co-wrote the 1955 film's script with Günther Weisenborn.
 Wolfgang Preiss won the German Federal Film Award for his role as the rebel army officer, Claus von Stauffenberg.
The German Resistance Memorial Center (German: "Gedenkstätte Deutscher Widerstand" ) is a memorial and museum in Berlin, capital of Germany.
 It was opened in 1980 in part of the Bendlerblock, a complex of offices in Stauffenbergstrasse (formerly Bendlerstrasse), south of the Großer Tiergarten in Tiergarten.
 It was here that Colonel Claus Schenk Graf von Stauffenberg and other members of the failed 20 July plot that attempted to assassinate Adolf Hitler were executed.
On 20 July 1944, Claus von Stauffenberg and other conspirators attempted to assassinate Adolf Hitler, Führer of Nazi Germany, inside his Wolf's Lair field headquarters near Rastenburg, East Prussia.
 The name Operation Valkyrie, originally referring to part of the conspiracy, has become associated with the entire event.
 The apparent aim of the assassination attempt was to wrest political control of Germany and its armed forces from the Nazi Party (including the SS) and to make peace with the western Allies as soon as possible.
 The underlying desire of many of the high-ranking Wehrmacht officers involved was apparently to show the world that not all Germans were like Hitler and the Nazi Party.
 The details of the conspirators' peace initiatives remain unknown, but they likely would have included unrealistic demands for the confirmation of Germany's extensive annexations of European territory.
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.
Claus Philipp Maria Schenk Graf von Stauffenberg (15 November 1907 – 21 July 1944) was a German army officer and member of the German nobility who was one of the leading members of the failed 20 July plot of 1944 to assassinate Adolf Hitler and remove the Nazi Party from power.
 Along with Henning von Tresckow and Hans Oster, he was one of the central figures of the German Resistance movement within the "Wehrmacht".
 For his involvement in the movement, he was executed by firing squad shortly after the failed attempt known as Operation "Valkyrie".
The End: Hitler's Germany 1944–45 is a 2011 book by Sir Ian Kershaw, in which Kershaw charts the course of World War II between the period of the failed 20 July plot to assassinate Adolf Hitler in July 1944, by Claus von Stauffenberg, until late May 1945, when the last of the Nazi regime's leaders were arrested and the government dissolved.
Kurt Freiherr von Plettenberg (31 January 1891 in Bückeburg – 10 March 1945 in Berlin) was a German forester, cavalry officer and a member of the German Resistance (Widerstand).
 He was involved in the preparations for the 20 July plot, an attempt to assassinate Adolf Hitler, Führer of the Third Reich.
 Plettenberg belonged to the circle of close friends which included Claus Schenk Graf von Stauffenberg, Johannes Popitz, Ludwig Beck, Ulrich von Hassell, Carl-Hans Graf von Hardenberg and Fabian von Schlabrendorff.
Werner Schrader (* 7 March 1895 in Rottorf (today part of Königslutter), Germany, † 28 July 1944 in Zossen) was a German military officer involved in several plots by the German Resistance including the famous 20 July plot, a coup d'état attempting to assassinate Adolf Hitler.
