Explain the purpose of the justinian code.

 At its simplest, the purpose Justinian had in mind was to organize the laws in the Byzantine Empire. It was a mammoth task, as you might well imagine. 

In doing this, the laws were put down in writing, presumably some old laws that had outlived their usefulness were discarded, and laws were enacted that dealt with situations that were contemporary at the time or could be foreseen as necessary for future generations.
