There was not much civilian resistance. When the Germans invaded Belgium and northern France in August 1914 they murdered thousands of civilians, and burned entire towns, such as the ancient university city of Louvain. This was pursuant to the official German policy of "schrecklichkeit" - "frightfulness". The cemeteries of Belgium are full of rows of crosses bearing the inscription "Fusilee par les Allemans 1914" (Shot by the Germans), right beside rows of identical crosses with the same inscription but the date 1940. This policy of frightfulness was intended to cow the civilian population into obedience and to remove any potential person around whom civilian resistance might coalesce. For instance, the Germans routinely shot the priest in every town. This policy also allowed the Germans to give vent to their anger, as they seemed to feel the Belgians were wickedly unobliging in attempting to resist militarily the righteous Imperial German Army on its chosen route to France. This was policy if no one offered any resistance. If anyone in civilian clothes actually did attempt to harm the Germans they extracted an even more terrible vengeance from their town. Civilians arming themselves and resisting invaders were not yet guerrillas, they were "franc tireurs", and liable to be immediately shot out of hand, if taken armed but not in uniform. The Germans of course alleged to the rest of the world that their thousands of Belgian and French civilian victims were franc tireurs.
Sinking civilian ships without warning (un-restricted submarine warfare).
There was widespread resentment over government controls.
After the United States entered World War I, the civilian population was able to meet labor demands by allowing women to work in factories. "Rosie, the Riveter" was a popular icon during this time used to entice women to work.
World War II, by a large margin. World War I saw about 8,500,000 military deaths. By contrast World War II produced between 20,000,000 and 30,000,000 military deaths, along with another 20,000,000 or so civilian deaths. Michael Montagne World War II, by about a factor of ten. Michael Montagne

About 6 million people
They fought a war against civilian merchant ships (Guerre de Course).
more than 8 1~2 million lives were lost in ww1
Most of World War 1 was characterized by stalemates caused by trench warfare. This caused the war to drag out for longer than expected, and casualties extended to the civilian populations of some countries.
It was similar, yes, but it had more meaningful changes, America was introduced to the Kamakazi style fighting of the Japanese and our Economy was in a better position that in world war 1.

2. It was the first ever war with more civilian than military casualties. Compare that to the Battle of Gettysburg in the American civil war. More Americans died in three days than their war for independance, war of 1812, and war with Mexico combined, but only one civilian death. Granted, most civilian deaths in world war 2 were from bombing, but it would still be less than military if there weren't millions who starved in the soviet union, most during the winter of '42-'43, one of the coldest on record.
World War II had an incredibly larger number of deaths if including both civilian and military loss of life. In the second World War, over 60 million people were killed, and in the first World War, approximately 37 million people were killed.
Overall, WWII did. There were more battles in more parts of the globe, and there were far more civilian casualties, particularly from bombing raids carried out by all sides.
