Ancient Greece was located in the Mediterranean region known as the Aegean Sea, this civilization was formed by 4 different geographic areas: 1) Peloponnese, this area was located in the southwestern peninsula and it only had a small part of land that connected it to the mainland, a famous city-state of this region is Sparta. 2) Central Greece, this area was above the Peloponnese, a famous city-State from this region is Athens. 3) Northern Greece, this big area grew -towards northeastern land thanks to conquest campaigns and was divided in 3 different sections: Thessaly, Epirus, and Macedonia. 4) A numerous groups of islands located in the Aegean Sea formed the last geographic area.
As the question says, the mountainous territory served as protections against invaders, but it also meant it was not easy to travel by land between regions, and that each city-State formed a particular way of life and culture. The regionalism in ancient Greece also implied a constant internal conflict between city-states like Sparta and Athens, and the inability of having a central government because of the big differences and conflicts between population.
There had been splits before i believe on three different occasions but this time was more definite due to a culmination of differences. The big one was when the Patriarch of Constantinople excommunicated the Pope after the Popes messengers interrupted a mass at the Church in Constantinople and once it got back to Rome the Pope excommunicated the Patriarch. There were other problems between the two lungs of the Church such as the Western Church added the filioque . The biggest problem that Historians say is there was just a plain language problem between the Latin and the Greek which created misunderstanding of beliefs.And there were also cultural differences which caused different understanding of beliefs. But thank GOD the excommunications have been lifted and the two Churches are getting closer to being one again.
Britain needed to resolve a conflict between the principles of free trade (which Britain was more and more adopting) and the institution of slavery.
Concerns about slave revolts indeed were indeed part of Britain's pragmatic decisions to end its participation in the slave trade in 1807 and phasing out slavery in its empire starting in 1834. But the other factor was that the Industrial Revolution was taking over how the British economy operated, and the institution of slavery no longer fit within the new, industrializing economy.
Along with those practical reasons, there was of course much moral pressure applied by the abolitionist movement. William Wilberforce was a key voice of conscience in Parliament from the moral side of the argument.
