The Kingdom of Germany was a big castle in the olden days, where a king lived with lots of people who helped him rule the land. The castle and the land around it were called Germany, and the kingdom was ruled by different kings over time. The kingdom was made up of many smaller areas called states or provinces, and each state had its own leaders, but they all listened to the king of Germany. The kingdom of Germany was located in Europe, and it lasted for a really long time, until it eventually became the country we know today as Germany.
