Answer: From early times the Greeks lived in independent communities isolated from one another by the landscape. Later these communities were organized into poleis or city-states. The mountains prevented large-scale farming and impelled the Greeks to look beyond their borders to new lands where fertile soil was more abundant.
The argument over the use and worship of idols greatly contributed to the Great Schism between the Eastern and Western Christian churches.
Missouri Compromise
The Missouri Compromise split the Louisiana Territory with the North being free from slavery and the South being allowed to have slavery.
The issue of slavery was a rising concern and with each state entering into the Union the balance of slave and free states was skewing. With a new land mass to be concerned with, the government needed a compromise to deal with new states coming into the Union in an effort to maintain slave v. free states. Missouri was entered as a slave state and Maine entered as a free state. The compromise also set the 36'30 line splitting Louisiana Territory. The compromise would last until 1850.
