The Burial Act of 1857 was a law made a long time ago that changed the way people could be buried in England and Wales. Before this law, people could only be buried in a certain way if they were a member of the Church of England. This meant that people who didn't belong to the church or believed in different things couldn't have the kind of funeral they wanted.
The Burial Act allowed people to choose how they wanted to be buried, regardless of what religion they followed, or if they followed a religion at all. This made it fair for everyone and stopped religious discrimination.
The law also said that people could be buried in a place of their choice, instead of being forced to be buried in a churchyard. This was important because people who didn't follow the Church of England were often not allowed to be buried in churchyards.
Overall, the Burial Act 1857 made it fairer for everyone to be buried how they want and allowed for people to choose their own burial spot.
