Okay, so imagine you're with some friends and you're all deciding what kind of game you want to play. Everyone has different ideas, but eventually you all agree on playing hide-and-seek.
Well, a long time ago, some grown-ups called politicians were like your friends and they needed to decide what their group, called a political party, believed in and wanted to do. They had different ideas and beliefs, so they had to come up with something they could all agree on, too.
That's when some of these politicians from a party in Germany called the Social Democratic Party came together in a town called Bad Godesberg. They talked about what they believed in and what they wanted to do for the people who voted for them.
After a lot of talking, they came up with something called the Godesberg Program. This was like a set of rules or ideas that all of the politicians in the party decided to follow. They agreed on things like making sure everyone had jobs and what they called "social justice" so everyone was treated fairly.
This Godesberg Program was important because it was a new way of thinking for the party. Before, they were more focused on just helping workers, but now they wanted to help everyone in the country. It was a big change for the party and helped make it more popular with more people.
