Stanisławów Ghetto (Polish: "getto w Stanisławowie" , German: "Ghetto Stanislau" ) was a Jewish World War II ghetto established in 1941 by the "Schutzstaffel" ("SS") in the prewar Polish city of Stanisławów in the south-eastern region of Kresy (now Ivano-Frankivsk, Ukraine) occupied by Germany after Operation Barbarossa.
 Before the joint Nazi-Soviet invasion of Poland in 1939 Stanisławów was the capital of the Stanisławów Voivodeship in the Second Polish Republic.
 The Soviets annexed the city to the Ukrainian SSR in 1939 along with the entire region, but renamed it as Ivano-Frankivsk in 1962, long after the war ended.
 In 1941 Stanisławów (then, Stanyslaviv) was overrun again, this time by the Wehrmacht army, in the course of the German attack on the Russian positions behind the Curzon Line (see map, marked in red), and incorporated it into their own "Distrikt Galizien", as the fifth district of the "Generalgouvernement".
The Łuck Ghetto (a.k.a. the Lutsk Ghetto, Polish: "getto w Łucku" , German: "Ghetto Luzk" ) was a Jewish World War II ghetto established in 1941 by the "Schutzstaffel" ("SS") in the prewar Polish city of Łuck (now Lutsk, Ukraine) occupied by Germany after Operation Barbarossa, in the south-eastern region of Kresy.
 Łuck was the capital of the Wołyń Voivodeship (1921–39) in the Second Polish Republic before the joint Nazi-Soviet invasion of Poland of 1939.
 The invading Soviets annexed the city to the Ukrainian SSR in 1939 along with the entire region, an renamed it as Луцьк (Lutsk).
The Białystok Ghetto (Polish: "getto w Białymstoku" ) was a World War II Jewish ghetto set up by Nazi Germany between July 26 and early August 1941 in the newly formed "Bezirk Bialystok" district of the Third Reich within Nazi occupied Poland.
 About 50,000 Jews from the vicinity of Białystok and the surrounding region were herded into a small area of the city, which was turned into the "Bezirk's" capital.
 The ghetto was split in two by the Biała River running through it "(see map)".
 Most inmates were put to work in the forced-labor enterprises for the German war effort, primarily in large textile, shoe and chemical companies operating inside and outside its boundaries.
 The ghetto was liquidated in November 1943 after the Białystok Ghetto uprising was crushed.
 All its inhabitants were either killed locally, or transported in Holocaust trains to the Majdanek and Treblinka extermination camps.
The history of the Curzon Line, with minor variations, goes back to the period following World War I.
 It was drawn for the first time by the Supreme War Council as the demarcation line between the newly emerging states, the Second Polish Republic, and the Soviet Union.
 The proposal was put forward by British Foreign Secretary George Curzon, to serve as a diplomatic basis for the future border agreement, and in that form, it never materialized because the war went on.
The Zdzięcioł Ghetto, Dzyatlava Ghetto or Zhetel Ghetto (in Yiddish) was a Jewish ghetto established by Nazi Germany in the town of Zdzięcioł in the occupied eastern part of the Republic of Poland (now Dziatłava, Belarus) during Holocaust in World War II.
 The Soviet forces invaded eastern Poland on 17 September 1939 and stationed in the Voivodeship area until the outbreak of their own war with Germany in June 1941.
 After the Soviet rapid retreat, and several months of Nazi ad-hoc persecution, on 22 February 1942 the new German authorities officially created a ghetto for all local Jews.
The Łódź Ghetto (German: "Ghetto Litzmannstadt" ) was a World War II ghetto established by the Nazi German authorities for Polish Jews and Roma following the 1939 invasion of Poland.
 It was the second-largest ghetto in all of German-occupied Europe after the Warsaw Ghetto.
 Situated in the city of Łódź, and originally intended as a preliminary step upon a more extensive plan of creating the "Judenfrei" province of Warthegau, the ghetto was transformed into a major industrial centre, manufacturing much needed war supplies for Nazi Germany and especially for the German Army.
 The number of people incarcerated in it was augmented further by the Jews deported from the Reich territories.
Lamina dura is compact bone that lies adjacent to the periodontal ligament, in the tooth socket.
 The lamina dura surrounds the tooth socket and provides the attachment surface with which the Sharpey's fibers of the periodontal ligament perforate.
 On an x-ray a lamina dura will appear as a radiopaque line surrounding the tooth root.
 An intact lamina dura is seen as a sign of healthy periodontium.
 Lamina dura, along with the periodontal ligament, plays an important role in bone remodeling and thus in orthodontic tooth movement.
Sambor Ghetto (Polish: "getto w Samborze" ) was a Jewish World War II ghetto established in March 1942 by the "Schutzstaffel" ("SS") in the prewar Polish city of Sambor in the south-eastern region of Kresy (now Sambir, Ukraine).
 Sambor was occupied by Nazi Germany twice, first during the joint German-Soviet invasion of Poland in 1939, and again, after the 1941 Operation Barbarossa.
 Before the war, Sambor was a county seat in the Lwów Voivodeship of the Second Polish Republic.
 The invading Germans handed the town over to the Soviets in accordance with the Nazi-Soviet Pact against Poland.
 Sambor was annexed to the Ukrainian SSR along with the entire region in the atmosphere of intimidation, and the NKVD terror.
 In 1941 the city was overrun again by the Wehrmacht army in the course of the German attack on the Soviet positions behind the Curzon Line (see map, marked in red), and incorporated it into their own "Distrikt Galizien".
 According to the Polish census of 1931 Jews constituted nearly 29 percent of the town's inhabitants, most of whom were killed during the Holocaust.
 Sambor (Sambir) is not to be confused with the much smaller Old Sambor (Stary Sambor, now Staryi Sambir) located close-by, although their Jewish history is inextricably linked together.
The Vilna Ghetto was a World War II Jewish ghetto established and operated by Nazi Germany in the city of Vilnius in the territory of Nazi-administered Reichskommissariat Ostland.
 During the some two years of its existence, starvation, disease, street executions, maltreatment, and deportations to concentration camps and extermination camps reduced the Ghetto's population from an estimated 40,000 to zero.
 Only several hundred people managed to survive, mostly by hiding in the forests surrounding the city, joining Soviet partisans, or sheltering with sympathetic locals.
Marcinkonys or Marcinkance Ghetto was a Jewish ghetto established in Marcinkonys, Lithuania, during the Holocaust.
 The ghetto was set up at the end of 1941 and covered the area of 1.5 ha , surrounded by barbed wire.
 Several hundred people lived in the improvised ghetto.
 On November 2, 1942, orders were given to liquidate the ghetto and transport the Jews to Treblinka and Auschwitz concentration camps.
 A squad of 15 Germans ordered the Jews to gather at the entrance at 8am to be "transported for labor."
 Witnesses present different accounts of further events.
 According to an official complaint written by forester Hans Lehmann, two of the Germans opened fire at the crowded Jews without a reasonable cause.
 Other authors present the events as a revolt inspired by Aaron Kobrowski, chairman of the Judenrat.
 Panicked Jews attempted to escape through the fence into the nearby forest or back into the ghetto.
 The Germans then searched the ghetto, shooting any Jews on sight and destroying five secret bunkers.
 In total, 105 or 132 Jews were shot.
 About a hundred Jews escaped and 45 of them survived the war.
 Hans Lehmann, who had joined the Nazi Party in 1933, was investigated and it was determined that he was sympathetic to the Jews and allowed them to escape.
 He was discredited and transferred.
 In 1943, Jewish partisans derailed a German train east of Białystok.
 Lehmann was among the captured Germans.
 He recognized by one of the escapees from Marcinkonys and executed for his role in the massacre.
