The National Grange of the Order of Patrons of Husbandry is a group of people who care about farmers and farming. They are like a club or a team that works together to make sure that farmers are doing well and being treated fairly.
The Grange started a long time ago, back in 1867. At that time, many farmers were struggling because they didn't have a lot of money and they didn't have a lot of power. They were having a hard time getting their crops to sell for a good price, and they were also having a hard time making sure that the government was listening to their needs.
So some farmers got together and started the Grange. They wanted to create a place where farmers could meet and share ideas, and also have more power when it came to laws that affected them.
Today, the Grange is still around and it's still helping farmers. They work to make sure that farmers have good resources and tools, and that they also have a strong voice when it comes to government policies.
Think of the Grange like a big family of farmers. They all care about each other and they work together to make sure that everyone is doing well.
