How did trench warfare contribute to a stalemate in world war 1

During the first few months, both sides tried flanking each other to beat them. This in turn, led to building fortifications to prevent being attacked on the sides. This sort of maneuvers and counter-maneuvers created trench networks extending from Switzerland to the English Channel.

It's worth noting that it wasn't just one long narrow trench. There were miles of switchbacks, communication trenches, supporting trenches, reserve trenches, and artillery placements. Also, no man's land wasn't always hundreds of yards long. Some points along the trench forward posts were literally within an arms reach of each other. All of this on top of a haphazard maze of barbed wire, machine guns, gas, and mines not too many soldiers were eager to charge headlong into battle for a few yards of ground. Some French soldiers even protested against futile attacks.

abraham lincoln, according to anyone who was connected with agriculture, represented the worst of northern politicians. shortly after lincoln was elected, south carolina seceded from the union. they along with other southern states, retained their anger. in a way, it was their own fault: the democrats were split in the south. some wanted slavery to be extended in other states that were about to join the union and some didn't want it badly enough. lincoln had a solid backing from his party: the republicans were united in not wanting slavery to be expanded.
