How was America changed by it's involvement in WWI?

I don't know but good luck

Explanation:

although the crusades failed to capture jerusalem, they had several major impacts on western europe. they increased the authority of the king: sometimes nobles died in battle without leaving an heir in which case the king got their land. kings passed taxes to pay for the crusades.

they had more african americans than any other state.

hope this , have a good day. c;
