Question

How was government administration in the Byzantine Empire changed by the empire's vulnerability to outside attack

Answer 1

Over time, its economic and military might waned and along with it, the empire's capacity to seize an opportunity. Add in civil unrest, natural disasters and powerful enemies such as the Arabs, Seljuk Turks, Bulgars, Normans, Slavs, and Ottoman Turks, and you can see why the Byzantine Empire eventually crumbled.
