I used to timeline to answer the question looking at the Timeline what trend can you find in the United States earlier years, and increasing number of states setting from the union, a gradual weakening of the federal government powers, a growth and support for the federal government in the north, a serious challenge to power the federal government
Based on the provided information from the timeline, the trend that can be observed in the United States' earlier years is a gradual weakening of the federal government powers. This is evident from the increasing number of states seceding from the union, which indicates a loss of control and authority by the federal government. Additionally, this weakening of federal government powers is further supported by the serious challenge to the power of the federal government.
However, it is important to note that the information provided is limited to the earlier years and does not provide a comprehensive overview of the entire history of the United States. Therefore, it is necessary to consider additional historical context and events to form a more complete understanding.
