What are three causes of the great schism in christianity?

Three causes of Great Schism:

There were points of doctrinal dispute (such as those I listed).  Ultimately, though, the biggest reason was the struggle over authority in the church.  In 1054 CE, there were mutual declarations of excommunication between the pope (in Rome) and the patriarch (in Constantinople) that  resulted in what is known as "The Great Schism" -- a monumental split between the western church (the Roman Catholic Church and what has become known as the Eastern Orthodox Church.   "Catholic" means universal -- the Roman pope was intent on asserting his leadership over all of Christendom.  "Orthodox" means "right teaching."  The Eastern patriarch and church were asserting their teachings to be right over against positions held in the West.  There were a number of doctrinal issues debated hotly between East and West over the centuries leading up to final break between the two halves of the church. But more than anything, the split came down to "church power" -- who held control over the church.  

- "the civil rights movements"

- "following the american civil war and abolition of slavery, the united states entered a period known as reconstruction, during which black americans continued to suffer from disenfranchisement, racial segregation, and economic oppression. beginning in the early 1950's, black americans launched a series of major campaigns of civil resistance, emphasizing the need for nonviolent protests and civil disobedience."

"such as the montgomery bus boycott of 1955-56, a campaign launched by rosa parks against the policy of racial segregation of the public transit system in alabama. “sit-ins” became popular across the american south, particularly in greensboro, north carolina, increase national sentiment."

- "the counterculture movement"

- "counterculture began to develop in the united states following the rise of conformity in american culture during the 1950s. by 1963, youth, particularly those of the white middle class, began rejecting the cultural standards and normality of their parents, opting for progressive attitudes instead. the movement gained momentum as the civil rights movement became increasingly successful and as the u.s. military intervention of vietnam began to take a negative turn."

"hippie counterculture moved further into popular culture following the summer of love in 1967 when thousands of people came together in the haight-ashbury neighborhood of san francisco. along with greenwich village in new york city, haight-ashbury became a hub for the counterculture movement."
