How did the byzantines to preserve greco roman culture?

The Eastern Roman Empire, or the Byzantine Empire as it is often known, survived for nearly a thousand years after the fall of Rome in the West. Ruled from Constantinople (modern day Istanbul), the Byzantine Empire was a direct continuation of the later Roman Empire and lasted from the year 330 CE to 1453.

the main reason that the constitution did not proclaim all men to be free and equal is because of the issue of slavery.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
