The citizens of Poland have the highest count of individuals who have been recognized by Yad Vashem as the Polish Righteous Among the Nations, for saving Jews from extermination during the Holocaust in World War II. There are 7,177 (as of 1 January 2021) Polish men and women conferred with the honor, over a quarter of the 27,921 recognized by Yad Vashem in total.  The list of Righteous Among the Nations is not comprehensive and it is estimated that hundreds of thousands of Poles concealed and aided tens of thousands of their Polish-Jewish neighbors. Many of these initiatives were carried out by individuals, but there also existed organized networks of Polish resistance which were dedicated to aiding Jews – most notably, the Żegota organization.
 In German-occupied Poland, the task of rescuing Jews was difficult and dangerous. All household members were subject to capital punishment if a Jew was found concealed in their home or on their property.[better source needed]
 Before World War II, Poland's Jewish community had numbered about 3,460,000 – about 9.7 percent of the country's total population. Following the invasion of Poland, Germany's Nazi regime sent millions of deportees from every European country to the concentration and forced-labor camps set up in the General Government territory of occupied Poland and across the Polish areas annexed by Nazi Germany. Most Jews were imprisoned in the Nazi ghettos, which they were forbidden to leave. Soon after the German–Soviet war had broken out in 1941, the Germans began their extermination of Polish Jews on either side of the Curzon Line, parallel to the ethnic cleansing of the Polish population including Romani and other minorities of Poland.
 As it became apparent that, not only were conditions in the ghettos terrible (hunger, diseases, executions), but that the Jews were being singled out for extermination at the Nazi death camps, they increasingly tried to escape from the ghettos and hide in order to survive the war. Many Polish Gentiles concealed their Jewish neighbors. Many of these efforts arose spontaneously from individual initiatives, but there were also organized networks dedicated to aiding the Jews. Most notably, in September 1942 a Provisional Committee to Aid Jews (Tymczasowy Komitet Pomocy Żydom) was founded on the initiative of Polish novelist Zofia Kossak-Szczucka, of the famous artistic and literary Kossak family. This body soon became the Council for Aid to Jews (Rada Pomocy Żydom), known by the codename Żegota, with Julian Grobelny as its president and Irena Sendler as head of its children's section.
 It is not exactly known how many Jews were helped by Żegota, but at one point in 1943 it had 2,500 Jewish children under its care in Warsaw alone. At the end of the war, Sendler attempted to locate their parents but nearly all of them had been murdered at Treblinka. It is estimated that about half of the Jews who survived the war (thus over 50,000) were aided in some shape or form by Żegota.
 In numerous instances, Jews were saved by entire communities, with everyone engaged, such as in the villages of Markowa and Głuchów near Łańcut, Główne, Ozorków, Borkowo near Sierpc, Dąbrowica near Ulanów, in Głupianka near Otwock, Teresin near Chełm, Rudka, Jedlanka, Makoszka, Tyśmienica, and Bójki in Parczew-Ostrów Lubelski area, and Mętów, near Głusk. Numerous families who concealed their Jewish neighbours were killed for doing so.
 Concerning:
the Sheltering of Escaping Jews.
   There is a need for a reminder, that in accordance with paragraph 3 of the decree of 15 October 1941, on the Limitation of Residence in the General Government (page 595 of the GG Register) Jews leaving the Jewish Quarter without permission will incur the death penalty.
    According to this decree, those knowingly helping these Jews by providing shelter, supplying food, or selling them foodstuffs are also subject to the death penalty.
    This is a categorical warning to the non-Jewish population against:
         1) Providing shelter to Jews,
         2) Supplying them with Food,
         3) Selling them Foodstuffs.

 During the occupation of Poland (1939–1945), the Nazi German administration created hundreds of ghettos surrounded by walls and barbed-wire fences in most metropolitan cities and towns, with gentile Poles on the 'Aryan side' and the Polish Jews crammed into a fraction of the city space. On 15 October 1941, the death penalty was introduced by Hans Frank, governor of the General Government, to apply to Jews who attempted to leave the ghettos without proper authorization, and all those who "deliberately offer a hiding place to such Jews". The law was made public by posters distributed in all major cities. The death penalty was also imposed for helping Jews in other Polish territories under the German occupation, but without issuing any legal act.
 Anyone from the Aryan side caught assisting those on the Jewish side in obtaining food was subject to the death penalty. The usual punishment for aiding Jews was death, applied to entire families. Polish rescuers were fully conscious of the dangers facing them and their families, not only from the invading Germans, but also from blackmailers (see: szmalcowniks) within the local, multi-ethnic population and the Volksdeutsche. The Nazis implemented a law forbidding all non-Jews from buying from Jewish shops under the maximum penalty of death.
 Gunnar S. Paulsson, in his work on history of the Warsaw Jews during the Holocaust, has demonstrated that, despite the much harsher conditions, Warsaw's Polish residents managed to support and conceal the same percentage of Jews as did the residents of cities in safer countries of Western Europe, where no death penalty for saving them existed.
 There are 7,177 officially recognized Polish Righteous – the highest count among nations of the world. At a 1979 international historical conference dedicated to Holocaust rescuers, J. Friedman said in reference to Poland: "If we knew the names of all the noble people who risked their lives to save the Jews, the area around Yad Vashem would be full of trees and would turn into a forest." Hans G. Furth holds that the number of Poles who helped Jews is greatly underestimated and there might have been as many as 1,200,000 Polish rescuers.
 Father John T. Pawlikowski (a Servite priest from Chicago) remarked that the hundreds of thousands of rescuers strike him as inflated.
