There are three main structural branches of the United States government. The executive branch, consisting of the president and his agencies and office, the legislative branch, which is the congress, and the Judicial branch which consists of all the courts and the supreme court at the top. They balance each other's powers out and build the US government.
Historically, there were three highly important documents when it came to the government. Articles of confederation, which established something like the first form of government that existed, then the US constitution, which is still used today and established how the government will actually work, and the Bill of rights, which was a set of amendments that established personal rights and freedoms.
The guiding principles of the US government are establishing democratic rule and peaceful transitions of government officials, while enabling free market economy and protecting people's rights which are mentioned in the declaration of independence as the unalienable ones, the rights to life, liberty, and the pursuit of happiness.
The Federalist Papers were a series of documents, reportedly 85 different ones, that substantiated the ratification of the Constitution. Essentially made to defend it's ratification against the anti-federalists.
