Warsaw, the capital of Poland, became a significant center for the Jewish community in Europe by the early 20th century, with a vibrant cultural and political life despite facing economic hardships. The establishment of the ghetto in 1940 marked the beginning of severe persecution, culminating in mass deportations and the Warsaw Ghetto Uprising in 1943, which was a significant act of resistance. The ghetto's destruction and the subsequent survival of a small number of Jews in bunkers highlighted the immense struggle against Nazi oppression during the Holocaust.
