Trench warfare was Intorduced in World War 1. By World War 2, really the end of ww1 on. they were outdated due to the use of tanks and their ability to roll over the barbed wire and trenches.
Trenches were built during wars, particularly in World War I, to provide soldiers with protection from enemy fire and to establish defensive positions. Engineers and soldiers would dig deep, narrow ditches into the ground, often reinforced with wood, sandbags, or metal to prevent collapse. The construction involved careful planning to create a network of trenches that included front-line, support, and communication trenches, allowing for movement and supply while minimizing exposure to danger. These trenches often became complex systems with bunkers, observation posts, and even underground tunnels.

The first year it was a war of pushing the enemy and then being pushed back. The Germans pushed a little too much and had to retreat really fast, but they received the order not to retreat after the former German borders. So, they built trenches on elevated ground and waited for the allies. After that it was just hiding in the trenches, waiting for the next assault to come or to be announced. Most of the dead perished because of the bad hygiene, or just lucky potshots.
Thousands of trenches were constructed during World War 1. Most had names for operational purposes but few names are remembered. EDIT: Are you thinking of World War 2 and the Maginot Line?
Trenches were built with traverses to enhance the safety and protection of soldiers during warfare, particularly in World War I. These traverses—earth or wooden barriers added at intervals—helped to limit the effects of enemy fire and shrapnel, making it harder for an attacking force to target soldiers directly. Additionally, they provided cover from overhead attacks and reduced the risk of mass casualties from artillery strikes, promoting better defensive positions. Overall, traverses improved the survivability of troops in the harsh conditions of trench warfare.

The second line trenches were defensive positions built behind the first line trenches during World War I. They served as a fallback for troops if the front line was breached, providing additional layers of defense and allowing for better strategic positioning. These trenches were often more fortified and equipped, facilitating counterattacks and troop movements. The design aimed to protect soldiers from enemy fire while maintaining operational capability.

Many things made it possible to fire from the trenches. Mortars and field artillery were often fired from trenches. Trenches usually had berms (low dirt walls) built in front of them with firing positions along the top of the berm. Trenches sometimes had benches or ladders for gunners and snipers.
Trench warfare used several different types of trenches. Firing trenches were used by soldiers to protect themselves while firing their weapons at their enemy. Cover trenches were often built next to the firing trenches as a second line of defense in case the enemy captured the firing trench. Support trenches were used as rest areas for off-duty troops, who sometimes lived in dugouts excavated in the sides of the trench. A network of reserve and communications trenches was used to bring supplies and fresh troops to the front.
To prtect the army from getting shot
It was called the none of the viro
After the war the trenches went away as the land returned to its original uses, but I found a couple of them left that you can visit. One is Vieil Armand in Alsace, and the trenches were mostly carved in stone so they are well preserved. Also, World War 1 trenches in the Meuse have been restored to their original condition so that people can visit them. The German trenches there were built with concrete reinforcements, but the French trenches had filled in over the years and had to be dug out again.
by digging trenches and connecting the rivers
they built trenches for procetion and they used it as a base.
They had to get there before the other side did, so that they could get an advance into making their trench, so before the other side come, they will be ready will their trenches!
The trenches were called saps and the people who dug them were called sappers.
