origins of Holocaust commemoration and research in Israel

As soon as World War II ended, many Holocaust survivors made their way to Palestine/Eretz Israel, then under British Mandate. What began as a trickle became a torrent after Israel became an independent state in May 1948. Holocaust survivors became a significant part of Israel's population. The survivors were often too traumatized to speak about their wartime experiences. In the early years of Israeli statehood, Holocaust remembrance became extremely politicized. One of the main points of the debate was how to strike a balance between the victims labeled as "martyrs" and "heroes". Who should be commemorated?
