Timeline of American Government History

Timeline of US Government
America's journey began with the Declaration of Independence in 1776, drafted primarily by Thomas Jefferson with help from Adams and Franklin, which officially broke ties with Great Britain. This led to the American Revolutionary War (1775-1783). After victory, the United States first operated under the Articles of Confederation (1781-1788), a weak system where states maintained sovereignty but the federal government couldn't tax, regulate trade, or enforce laws.
The flaws in this system became painfully obvious during Shay's Rebellion (1786-1787), prompting leaders to convene the Constitutional Convention in 1787. Though originally intended to just revise the Articles, Washington, Madison, and Hamilton led efforts to create an entirely new government structure. The convention's most significant achievement was the Great Compromise, which resolved the conflict between large and small states through a bicameral legislature.
The Constitution faced opposition from Anti-federalists, who worried about centralized power. To address these concerns, the Bill of Rights – the first ten amendments – was added, protecting fundamental freedoms like speech, religion, and fair treatment under law. These amendments include protections from unreasonable searches, the right to bear arms, due process, and the right to a speedy trial.
Quick Fact: The amendment process requires either a two-thirds vote in both the House and Senate OR a Constitutional Convention called by two-thirds of state legislatures – showing how the founders made changing the Constitution possible but purposefully difficult!
Since its adoption, the Constitution has been amended 27 times in total. Key amendments beyond the Bill of Rights abolished slavery (13th), guaranteed equal protection (14th), gave voting rights to Black men (15th) and later to women (19th), limited presidential terms (22nd), and lowered the voting age to 18 (26th). Each amendment represents America's ongoing effort to form "a more perfect union."

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.
This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.
Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
