The Rogers Act of 1924, often referred to as the Foreign Service Act of 1924, is the legislation that merged US diplomatic and consular services into the US Foreign Service. The purpose of this Act was to promote a better relationship between the US and the countries that take part in the trades.

the ss was the main organization responsible for the genocidal murder of around six million people of european ethnic minorities, essentially jews, in the holocaust. the members of all its branches committed war crimes and crimes against humanity during the second world war (1939-1945). likewise, the ss were involved in commercial enterprises and exploited the inmates of the concentration camps as slave laborers.

the tortures and assassinations committed by the ss were the result of an ideology developed long before the armed conflict, this ideology was based on the racial supremacy of the germans over the rest.
