What was the Declaration? Why do Americans continue to celebrate its public announcement as the birthday of the United States, July 4, 1776? While that date might just mean a barbecue and fireworks to some today, what did the Declaration mean when it was written in the summer of 1776?

In the early days of 1776, most Americans were naďve when assessing just how difficult the war would be. Great initial enthusiasm led many men to join local militias where they often served under officers of their own choosing. Yet, these volunteer forces were not strong enough to defeat the British Army, which was the most highly trained and best equipped in the world. Furthermore, because most men preferred serving in the militia, the Continental Congress had trouble getting volunteers for General George Washington's Continental Army. This was in part because, the Continental Army demanded longer terms and harsher discipline.

Although Loyalists were steadfast in their commitment to remain within the British Empire, it was a very hard decision to make and to stick to during the Revolution. Even before the war started, a group of Philadelphia Quakers were arrested and imprisoned in Virginia because of their perceived support of the British. The Patriots were not a tolerant group, and Loyalists suffered regular harassment, had their property seized, or were subject to personal attacks.

The American Revolution needs to be understood in a broader framework than simply that of domestic events and national politics. The American Revolution started a trans-Atlantic Age of Revolution. Tom Paine, the author of Common Sense (1776), permits a biographical glimpse of the larger currents of revolutionary change in this period. Paine was English-born and had been in the American colonies less than two years when he wrote what would become the most popular publication of the American Revolution.

The 13th Amendment to the United States Constitution, ratified just months after the end of the American Civil War, abolished enslavement and involuntary servitude—except as a punishment for a crime—in the entire United States. As passed by Congress on January 31, 1865, and ratified by the states on December 6, 1865, the full text of the 13th Amendment reads:

The states now faced serious and complicated questions about how to make their rules. What did it mean to replace royal authority with institutions based on popular rule? How was "popular sovereignty" (the idea that the people were the highest authority) to be institutionalized in the new state governments? For that matter, who were "the people"?

While the state constitutions were being created, the Continental Congress continued to meet as a general political body. Despite being the central government, it was a loose confederation and most significant power was held by the individual states. By 1777 members of Congress realized that they should have some clearly written rules for how they were organized. As a result the Articles of Confederation were drafted and passed by the Congress in November.

The central failure of the Congress was related to its limited fiscal power. Because it could not impose taxes on the states, the national government's authority and effectiveness was severely limited. Given this major encumbrance, the accomplishments of the Congress were quite impressive. First of all, it raised the Continental Army, kept it in the field, and managed to finance the war effort.

The economic problems faced by the Congress deeply touched the lives of most Americans in the 1780s. The war had disrupted much of the American economy. On the high seas the British navy had great superiority and destroyed most American ships, crippling the flow of trade. On land, where both armies regularly stole from local farms in order to find food, farmers suffered tremendously.

The 14th Amendment to the United States Constitution deals with several aspects of U.S. citizenship and the rights of citizens. Ratified on July 9, 1868, during the post-Civil War era, the 14th, along with the 13th and 15th Amendments, are collectively known as the Reconstruction Amendments. Although the 14th Amendment was intended to protect the rights of formerly enslaved people, it has continued to play a major role in constitutional politics to this day.

The 1780s has often been termed the "critical period" for the new nation. The dangers posed by economic crisis and the disillusionment that came with the collapse of Revolutionary expectations for dramatically improved conditions combined to make the decade a period of discontent, reconsideration, and, in the end, a dramatic new proposal for redirecting the nation. Just as the Revolution had been born of diverse and sometimes conflicting perspectives, even among the Patriots, so too, ideas about the future of the United States in the 1780s were often cast in dramatic opposition to one another.

The crisis of the 1780s was most intense in the rural and relatively newly settled areas of central and western Massachusetts. Many farmers in this area suffered from high debt as they tried to start new farms. Unlike many other state legislatures in the 1780s, the Massachusetts government didn't respond to the economic crisis by passing pro-debtor laws (like forgiving debt and printing more paper money). As a result local sheriffs seized many farms and some farmers who couldn't pay their debts were put in prison.

At the same time that Shays' Rebellion attempted to force the government to take a new course of action in response to hard times, another group of Americans gathered to consider a very different vision for the future of the republic. The group was especially concerned about economic policy and the way that competing state policies often worked at cross-purposes. Responding to such concerns, the Virginia legislature called for a convention to meet in Annapolis, Maryland, in 1786 to discuss commercial matters. Only twelve delegates came from five states, but they agreed to meet again the next year in Philadelphia.

In spite of the common vision and status that linked most of the delegates to the Philadelphia Convention, no obvious route existed for how to revise the Articles of Confederation to build a stronger central government.

"Representation" remained the core issue for the Philadelphia Convention. What was the best way for authority to be delegated from the people and the states to a strengthened central government?

The 15th Amendment, ratified on February 3, 1870, extended the right to vote to Black American men seven years after the emancipation proclamation deemed the enslaved population free. Giving Black men voting rights was yet another way for the federal government to recognize them as full American citizens.

A framework for a new and stronger national government had been crafted at the Philadelphia Convention by a handful of leaders. But how could their proposed system be made into law?

The 16th Amendment to the United States Constitution gives Congress the power to collect a federal income tax from all individuals and businesses without sharing or “apportioning” it among the states or basing the collection on the U.S. Census.

The National Park Service provides an account of the 1733 Slave Insurrection, the first instance in which enslaved people took control of a colony. The insurrection served as a spark to later slave revolts that would take place. They took fate into their own hands as they rose against their oppressors. The insurrection marks a significant historical event for Virgin Islanders who continue to recognize the men and women who risked their lives for freedom.

Presidents Washington ($1), Lincoln ($5), Jackson ($20), and Grant ($50) all appear on currency. But what about this guy Alexander Hamilton on the ten-spot? How did he get there? A sawbuck says you'll know the answer after reading this piece.
