Why did young british men enlist and fight in ww1?

AnswerThey joined up for many reasons.

I think that the main reason was because if a man didn't join the army, he was seen as a coward and people didn't regard him as a man, they thought of him as a boy, so it was mainly to keep their pride and dignity.

They also probably just wanted to help win the war, serve their country and make their family proud.

They felt a loyalty to their country and they felt that they had to fight for their country.

I hope I've helped :)
