Context paragraphs:
Joachim von Ribbentrop: Ulrich Friedrich Wilhelm Joachim von Ribbentrop (30 April 1893 – 16 October 1946), more commonly known as Joachim von Ribbentrop, was Foreign Minister of Nazi Germany from 1938 until 1945.

Konstantin von Neurath: Konstantin Hermann Karl Freiherr von Neurath (2 February 1873 – 14 August 1956) was a German diplomat remembered mostly for having served as Foreign minister of Germany between 1932 and 1938.  Holding this post in the early years of Adolf Hitler's regime, Neurath was regarded as playing a key role in the foreign policy pursuits of the Nazi dictator in undermining the Treaty of Versailles and territorial expansion in the prelude to World War II, although he was often tactically if not necessarily ideologically.  This aversion eventually induced Hitler to replace Neurath with the more compliant and fervent Nazi Joachim von Ribbentrop.

Molotov–Ribbentrop Pact negotiations: The Molotov–Ribbentrop Pact was an August 23, 1939, agreement between the Soviet Union and Nazi Germany colloquially named after Soviet foreign minister Vyacheslav Molotov and German foreign minister Joachim von Ribbentrop.  The treaty renounced warfare between the two countries.  In addition to stipulations of non-aggression, the treaty included a secret protocol dividing several eastern European countries between the parties.

Special Bureau for India: Sonderreferat Indien, variously translated into English as, Special Bureau for India, Special India Bureau, or Section for Indian Affairs, was a section or bureau established within the Information Department of the Foreign Office of Nazi Germany in late spring 1941 in response to a proposal or memorandum written by the Indian nationalist Subhas Chandra Bose, who had arrived in Germany in early April of that year.  The main function of the bureau was to aid Bose in his work, to liaise with Bose, and to mobilize an Indian Legion, comprising Indian POWs captured by Erwin Rommel's Afrika Korps, to aid the German military in a future land invasion of India.  A military "intervention" in India, one of the two major points in Bose's proposal, had at first received a lukewarm response from the German Foreign Minister Joachim von Ribbentrop, but shortly afterwards it received the unexpected support of Adolf Hitler, who saw the battle for India as the natural aftermath of a successful German invasion of Russia and a chance to deliver the ultimate blow to the British Empire.

1939 German ultimatum to Lithuania: 1939 German ultimatum to Lithuania was an oral ultimatum presented to Juozas Urbšys, Foreign Minister of Lithuania, by Joachim von Ribbentrop, Foreign Minister of Nazi Germany, on 20 March 1939.  The Germans demanded that Lithuania give up the Klaipėda Region (also known as the Memel Territory), which had been detached from Germany after World War I, or the Wehrmacht would invade Lithuania.  After years of rising tension between Lithuania and Germany, increasing pro-Nazi propaganda in the region, and continued German expansion, the demand was expected.  The ultimatum was issued just five days after the Nazi occupation of Czechoslovakia.  The four signatories of the 1924 Klaipėda Convention, which had guaranteed the protection of the "status quo" in the region, did not offer any material assistance.  The United Kingdom and France followed a policy of appeasement, while Italy and Japan openly supported Germany.  Lithuania was forced to accept the ultimatum on 22 March.  For Germany it was the last territorial acquisition before World War II; for Lithuania it was a major downturn in economy and morale; for Europe it was further escalation in pre-war tensions.

Richard Schulze-Kossens: Richard Schulze (2 October 1914 in Spandau, Berlin – 3 July 1988 in Düsseldorf) was a Waffen-SS officer during the Second World War who reached the rank of SS-"Obersturmbannführer" (lieutenant colonel).  During World War II, Schulze served as a Waffen-SS adjutant to the foreign minister Joachim von Ribbentrop and later commanded the 38th SS Division Nibelungen, SS-Junkerschule Bad Tölz.  He was awarded the German Cross in Gold and the Finnish Order of the Cross of Liberty.

German–Soviet Frontier Treaty: The German-Soviet Frontier Treaty was a second supplementary protocol, of the 1939 Hitler-Stalin Pact (known as the "German-Soviet Treaty of Nonaggression", or by its original name of the "German–Soviet Treaty of Friendship, Cooperation and Demarcation").  It was a secret clause as amended on September 28, 1939 by Nazi Germany and the Soviet Union after their joint invasion and occupation of sovereign Poland.  It was signed by Joachim von Ribbentrop and Vyacheslav Molotov, the foreign ministers of Germany and the Soviet Union respectively, in the presence of Joseph Stalin.  The treaty was a follow-up to the first secret protocol of the Molotov–Ribbentrop Pact signed on August 23, 1939 between the two countries prior to their invasion of Poland and the start of World War II in Europe.  Only a small portion of the protocol which superseded the first treaty was publicly announced while the spheres of influence of Nazi Germany and the Soviet Union remained classified.  The third secret protocol of the Pact was signed on January 10, 1941 by Friedrich Werner von Schulenberg, and Molotov, whereas Germany renounced its claims to portions of Lithuania, only a few months before their anti-Soviet Operation Barbarossa.

Paul Carell: Paul Carell (born Paul Karl Schmidt; 2 November 1911, Kelbra – 20 June 1997) was an "Obersturmbannführer" (lieutenant colonel) in the "Allgemeine-SS" (General SS) in Nazi Germany.  He worked as the chief press spokesman for Joachim von Ribbentrop's Foreign Ministry, where he formulated propaganda for the foreign press.  In this capacity during World War II, he maintained close ties with the Wehrmacht.  One of his specialties was the "Jewish question".  After the war, he became a successful author, mostly of revisionist books that romanticized and whitewashed the Wehrmacht.

German–Soviet Axis talks: In October and November 1940, German–Soviet Axis talks occurred concerning the Soviet Union's potential entry as a fourth Axis Power in World War II.  The negotiations, which occurred during the era of the Molotov–Ribbentrop Pact, included a two-day Berlin conference between Soviet Foreign Minister Vyacheslav Molotov, Adolf Hitler and German Foreign Minister Joachim von Ribbentrop, followed by both countries trading written proposed agreements.  After two days of negotiations from 12 to 14 November 1940, Germany presented the Soviets with a draft written Axis pact agreement defining the world spheres of influence of the four proposed Axis powers (Japan, Germany, Soviet Union, Italy).  Hitler, Ribbentrop and Molotov tried to set German and Soviet spheres of influence; Hitler encouraged Molotov to look south to Iran and eventually India while preserving German access to Finland's resources, and to remove Soviet influence in the Balkans.  Molotov remained firm, seeking to remove German troops from Finland and gain a warm water port in the Balkans.  Soviet foreign policy calculations were predicated by the idea that the war would be a long - term struggle and therefore German claims that Britain would be defeated swiftly were treated with scepticism.  In addition Stalin sought to remain influential in Bulgaria and Yugoslavia.  These factors resulted in Molotov taking a firm line.  According to a Columbia University academical source, on 25 November 1940, the Soviets presented a Stalin-drafted written counterproposal where they would accept the four power pact, but it included Soviet rights to Bulgaria and a world sphere of influence centered on the area around modern Iraq and Iran.  Germany did not respond, leaving the negotiations unresolved.  Regarding the counterproposal, Hitler remarked to his top military chiefs that Stalin "demands more and more", "he's a cold-blooded blackmailer" and that "a German victory has become unbearable for Russia" so that "she must be brought to her knees as soon as possible."  Germany broke the Molotov-Ribbentrop Pact in June 1941 by invading the Soviet Union.

Martin Luther (diplomat): Martin Franz Julius Luther (] ; 16 December 1895 – 13 May 1945) was an early member of the Nazi Party.  He served as an advisor to Foreign Minister Joachim von Ribbentrop, first in the "Dienststelle Ribbentrop" ("Ribbentrop Bureau"), and later in the "Auswärtiges Amt" ("Foreign Office") as a diplomat when von Ribbentrop replaced Konstantin von Neurath.  He participated in the Wannsee Conference, at which the Final Solution was planned; it was the 1947 discovery of his copy of the minutes that first made the Allied powers aware that the conference had taken place and what its purpose was.
