<span>They started because the Persian Empire expanded into Ionia where there were several Greek colonies. The colonists sent back to Greece for help. The Athenians sent a few ships to help the colonists, but the cities were taken any way. To put the mainland Greeks in their place, the Persians sent a small force to punish the Greeks. So begins the battle of Marathon. </span>
During World War I, conscientious objectors were used to support "relief efforts in France," although this was not universally the case, and many remained at home.
The “Rise of Communism” was the period of time which is known as the birth of communism… In 1917 Tsar Nicholas II was overthrown and Vladimir Lenin took his place as one of the founding fathers of communism. Communism is basically a form of government where all major productive resources, such as mines, and farms, are owned publicly, and every person is paid equally or according to their individual needs. Hope this helps.
"Appeasement is a diplomatic policy aimed at avoiding war by making concessions to an aggressor."
Prior to World War Two the British and French tried Appeasing Hitler by agreeing to return the Sudentenland for example to Germany and didn't interfere or prevent the Germans from reoccupying the Rhineland.

In the process by avoiding conflict the Brits were able to ready for a possible war and better able to deal with it once it happened; example being perfecting radar prior to the Battle of Britain.
Hope that helps :)
