The Madagascar Plan was a plan of Nazi Germany that suggested the relocation of European Jews to the island of Madagascar. This was planned to take place after conquering France, due to the fact that Madagascar was part of France at that time.
The plan never took place for two main reasons. In order for the plan to be conducted, Germany needed to be able to control the naval forces of Great Britain, which never happened. Moreover, the program was abandoned in favour of what is called the "Final Solution," which was the murder of all Jews in Europe.
