How did Constantine carry out Diocletian’s reforms to try to help strengthen the declining empire?

Diocletian created a new administrative system called the tetrarchy (rule by 4) and increased the # of provinces. He also instituted a policy that Romans had to worship the emperor and state gods and established minimum wage. Constantine stripped power from Roman senate and created extreme power for the emperor.

A- the diary of a Jewish prisoner at Auschwitz

Explanation:

The Nuremberg trials were when they charged Nazi officers and soldiers and charged them for crimes against the Jewish people.  Auschwitz was a concentration camp, where Jews were held and killed.  Even though very few Jews survived from there to tell the courts what happened, a diary of events from a person directly involved qualifies as a primary source.

(A secondary source, for example, is a person who heard about it from someone who was there, but was not actually present for the event.)
