On the night of June 16, 1775, a detail of American troops acting under orders from Artemas Ward moved out of their camp, carrying picks, shovels, and guns. They entrenched themselves on a rise located on Charleston Peninsula overlooking Boston. Their destination: Bunker Hill.

Does the right to pursue happiness include access to a free public education? Do all Americans have an unalienable right to health care under this happiness umbrella? Should the unemployed be assisted in their times of need?

Huitzilopochtl, God of the Sun, was the Aztec principal god. He had an insatiable appetite for blood. Under his urging, the Aztecs rose from a band of primitive farmers to become the bloodiest civilization of the early Americas. Many Central America cultures indulged in human sacrifice. The Aztec practiced it on an industrial scale, sacrificing tens of thousands of victims each year.

In the wake of Columbus' historic voyage in 1492, expeditions, especially from Imperial Spain, swarmed into Aztec territory. They came in search of gold and souls — gold to enrich the coffers of the Spanish king (and their own), and heathen souls to rescue for Christianity. Within a generation, America's ancient civilizations were crushed. Both the Aztec and Inca Empires collapsed after campaigns lasting just a couple of years. How did they fall so fast? Historians suggest many causes.

During the war years, those Americans not involved in warfare were doing their best just trying to survive. Farmers continued to grow food, artisans continued to practice their trades, and merchants attempted to maintain their businesses. Despite efforts to maintain business as usual, the entire social landscape was changed.

At Valley Forge, there were shortages of everything from food to clothing to medicine. Washington's men were sick from disease, hunger, and exposure. The Continental Army camped in crude log cabins and endured cold conditions while the Redcoats warmed themselves in colonial homes. The patriots went hungry while the British soldiers ate well.

The Battle of Saratoga was the turning point of the Revolutionary War. The scope of the victory is made clear by a few key facts: On October 17, 1777, 5,895 British and Hessian troops surrendered their arms. General John Burgoyne had lost 86 percent of his expeditionary force that had triumphantly marched into New York from Canada in the early summer of 1777.

Nowhere was the victory at Saratoga more noted than in France, which had been tentative in its efforts to assist the Americans. France's interest in the American fight for independence stemmed from France's humiliating defeat during the Seven Years War at the hands of its ancient enemy, England.

Although the American military was still enduring losses in 1780, the French were making a difference. The French navy was disrupting the British blockade. French commanders such as Lafayette and Rochambeau earned the respect and admiration of the American troops.

Liberty, republicanism, and independence are powerful causes. The patriots tenaciously asserted American rights and brought the Revolution. The Revolution brought myriad consequences to the American social fabric. There was no Reign of Terror as in the French Revolution. There was no replacement of the ruling class by workers' groups as in revolutionary Russia. How then could the American Revolution be described as radical? Nearly every aspect of American life was somehow touched by the revolutionary spirit. From slavery to women's rights, from religious life to voting, American attitudes would be forever changed.

Beneath the layer of the national government lies a complex web of state and local officials and institutions. The nation's founders concern over tyranny transcended their separation of power among the three branches of government. Power is also divided by level, with each layer performing its designated responsibility. States and communities would even have the freedom to design their own institutions and create their own offices. This creates a multitude of "laboratories" where government leaders at any level could see which systems were successful and which were problematic.

The vast majority of government employees work for local and state åÑ not the federal åÑ governments. Teachers, policemen, clerks at the motor vehicle office. Many of these people are state and local employees. This seems to confirm the general notion that government is in fact "closer to the people," and therefore more democratic. But the real evidence is contradictory.

Life, liberty and the pursuit of happiness simply did not seem consistent with the practice of chattel slavery. How could a group of people feel so passionate about these unalienable rights, yet maintain the brutal practice of human bondage? Somehow slavery would manage to survive the revolutionary era, but great changes were brought to this peculiar institution nevertheless.

During the colonial era, Americans were bound by British law. Now, they were no longer governed by the Crown or by colonial charter. Independent, Americans could seek to eliminate or maintain laws as they saw fit. The possibilities were endless. Republican revolutionary sentiment brought significant change during the immediate postwar years.

Paying taxes is surely everyone's least favorite government-related activity. But taxing citizens is one of the concurrent powers of government. Federal, state, and local levels all have the power to tax.

Every society needs a set of rules by which to operate. After the colonies declared independence from Great Britain, they had to write their own constitutions. Impassioned with the republican spirit of the Revolution, political leaders pointed their ideals toward crafting "enlightened" documents. The result was thirteen republican laboratories, each experimenting with new ways of realizing the goals of the Revolution. In addition, representatives from all the colonies worked together to craft the Articles of Confederation, which itself provided the nascent nation with invaluable experience.

Public education is the single largest expenditure for state and local governments across the nation. Yet it is arguably the most criticized. Many people charge that public schools are faltering and that American academic achievements are far behind those in other countries. In recent years, many states and localities have experimented with improving public schools.

Women's role in society was altered by the American Revolution. Women who ran households in the absence of men became more assertive. Abigail Adams, wife of John, became an early advocate of women's rights when she prompted her husband to "Remember the Ladies" when drawing up a new government.

The world at the turn of the 21st century was becoming smaller, as global interconnections made distant places seem close. At the same time, bloody nationalist conflicts turning neighbor against neighbor still raged. Government leaders around the world examined their own systems and each others to chart a course for the new millennium.

The war for American independence began with military conflict in 1775 and lasted at least until 1783 when the peace treaty with the British was signed. In fact, Native Americans in the west (who were allied with the British, but not included in the 1783 negotiations) continued to fight and didn't sign a treaty with the United States until 1795. The Revolution was a long, hard, and difficult struggle.
