describe one of the main causes of world war 1 and explain how that cause led to the outbreak of the war

Murder of franz Ferdinand and his wife.

Explanation:

For a while then, Serbia and Austria Hungary had a bitter relation. Austria Hungary had, at that time, annexed bosnia and herzegovina.

When franz, the crown prince of Austria Hungary and his wife were killed in Bosnia, Serbia and the black hand society were suspected and blamed.

Thus, the king of Austria Hungary sent a list of unfulfillable demands to Serbia and when serbia denied, Austria Hungary declared war on serbia which can be marked as the start of world war.

this is how the murder of the prince was a breaking point of the war

the answer is a) the proclamation of 1763.

the committees of correspondence were the american colonies’ means for maintaining communication lines in the years before the revolutionary war. in 1764, boston formed the earliest committee of correspondence to encourage opposition to britain’s stiffening of customs enforcement and prohibition of american paper money. the following year, new york formed a similar committee to keep the other colonies notified of its actions in resisting the stamp act. in 1773, the virginia house of burgesses proposed that each colonial legislature appoint a committee for intercolonial correspondence. the exchanges that followed built solidarity during the turbulent times and bring about the formation of the first continental congress in 1774.
