What was a major contribution of the byzantine empire? 1. adoption of democratic ideas from russia 2. spread of humanism and secularism across europe 3. reunification of eastern and western christendom 4. preservation of greek and roman culture

The answer is 4 The reason behind this is because when the Roman Empire segregated into two halves, the Eastern Empire carried on traditional Roman attitudes, values, beliefs and of course the Christian Religion. Later on, as time progressed the influence of neighbouring Greece and the mixture of both cultures through social interaction and Eastern Roman conquests was evident. Basically the integration of Greek provinces into the Eastern Roman Empire consequently caused both cultures to be preserved.
