Why was d-day important and when did it happen? what was the official name of this military operation?

D-day was important because it allowed Allied troops to enter France and advance toward Germany. D-day happened on June 6, 1944. It was called Operation Overlord.

Ifound this on google “simply, the working conditions were terrible during the industrial revolution. as factories were being built, businesses were in need of workers. with a long line of people willing to work, employers could set wages as low as they wanted because people were willing to do work as long as they got paid.” i hope this you for what your looking for.
