What is what does reich mean?

"Reich" is a German word that is often translated as "empire" or "realm". It can also refer to a state or a nation, especially in a historical context. In the 20th century, it was famously used in the name of Nazi Germany, which was officially known as the "Third Reich" (Drittes Reich). The term can have connotations of authoritarianism, expansionism, and militarism, but it can also be used in a more neutral or descriptive sense.
