Okay kiddo, let me explain. The Leicestershire Miners' Association was a group of people who worked in mines in a place called Leicestershire, which is in England. They all worked together to make sure they had good working conditions and fair pay.
You know how when you go to school, you have teachers who make sure you have everything you need and that the school is safe for you to be in? Well, the Leicestershire Miners' Association was like that, but for people who worked in the mines. They looked out for each other and tried to make things better for everyone who worked in the mines.
Mining is a very hard job. Most of the time, miners are underground digging for things like coal or gold. It can be very dangerous because there is not a lot of air and the ground can cave in. So, it's really important for miners to work together and make sure they are safe.
The Leicestershire Miners' Association also helped their members when they were sick or injured. They made sure they got the medical attention they needed and had enough money to take care of themselves and their families while they were recovering.
Overall, the Leicestershire Miners' Association was a group of people who worked hard to make sure everyone who worked in the mines had good working conditions, fair pay, and support when they needed it.
