Investigate the people, events, and ideas that have shaped the United States from the end of the Civil War through today, while applying what you learn to real-world problems. We study the US History to honor and appreciate the founders of our American nation and those who contributed to building and developing the United States but also to find patterns in the American history in order to learn from successful experiences and past mistakes in order to advocate for better and safer choices to benefit the current and future American generations.
