Older times - To make offerings and gifts to the spirits believed to come out on Halloween night.

The tradition of wearing costumes on Halloween is that In the 19th century , the winter days were full of constant worry. People feared of running into ghosts. To avoid this, people would wear masks when they left their homes after dark. People would leave bowls of food outside their house to please the ghosts and prevent them from attempting to enter their homes.EVEN I AM UNSURE ABOUT THIS THOUGH!
Shortages of food and homes
It started when families put food on their doorsteps to ward off hungry spirits from coming into their houses. That's all i know, but i suspect that beggars came and took the food for themselves. Then maybe the families got the idea to hand out food. They may have started handing out sweets as well. Then perhaps they started dressing up as spirits and stuff. I really dont know, but thats my theory. I hope this was helpful.
