Being a warrior in feudal Japan was more than just a job. It was a way of life. The collapse of aristocratic rule ushered in a new age of chaos — appropriately called the Warring States period (c.1400-1600) — in which military might dictated who governed and who followed.

All countries have rules that determine who is a citizen, and what rights and responsibilities come with citizenship. In the United States, the 14th Amendment gives constitutional protection of the basic rights of citizenship: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the States wherein they reside." So citizenship is conferred on the basis of place of birth and the process of naturalization.

In the summer that followed Parliament's attempt to punish Boston, sentiment for the patriot cause increased dramatically. The printing presses at the Committees of Correspondence were churning out volumes.

Discusses the historical development of Japanese martial arts such as aikido and judo.

For the first time in centuries, Japan was relatively peaceful. The strict political and social policies of Ieyasu and subsequent shoguns ushered in a golden age of economic and cultural prosperity.

Times had taken a sharp turn for the worse. Lexington and Concord had changed everything. When the Redcoats fired into the Boston crowd in 1775, the benefit of the doubt was granted. Now the professional imperial army was attempting to arrest patriot leaders, and minutemen had been killed in their defense. In May 1775, with Redcoats once again storming Boston, the Second Continental Congress convened in Philadelphia.

Americans could not break their ties with Britain easily. Despite all the recent hardships, the majority of colonists since birth were reared to believe that England was to be loved and its monarch revered. Yet there were the terrible injustices the colonists could not forget. Americans were divided against themselves. Arguments for independence were growing. Thomas Paine would provide the extra push.

The moment had finally come. Far too much bad blood existed between the colonial leaders and the crown to consider a return to the past. More and more colonists felt deprived by the British not only of their money and their civil liberties, but their lives as well. Bloodshed had begun over a year ago and there seemed little chance of a ceasefire. The radical wing of the Continental Congress was gaining strength with each passing day. It was time for a formal break with mother England. It was time to declare independence.

In the 1500s, when Spanish conquistadors appeared, two vast empires, those of the Aztecs and the Incas, dominated Central and South America. Both possessed divine kings, both were fractured by internal dissent, and both quickly succumbed to the Spanish onslaught. The physical remains of all these cultures lay dormant for centuries, until science and curiosity demanded their exploration.

Public policy is a goal-oriented course of action that the government follows in dealing with a problem or issue in the country. Public policies are based on law, but many people other than legislators set them. Individuals, groups, and even government agencies that do not comply with policies can be penalized. This complicated process goes through a predictable series of steps:

How could the Americans ever hope defeat the mighty British Empire in a military conflict? Americans faced seemingly impossible obstacles. When the guns fired at Lexington and Concord in 1775, there was not yet even a Continental Army. Those battles were fought by local militias. Few Americans had any military experience, and there was no method of training, supplying, or paying an army.

The British seemed unbeatable. During the previous 100 years, the British had enjoyed triumph after triumph over nations as powerful as France and Spain. At first glance, the odds were clearly against the Americans. A closer look provides insight into how the underdogs emerged victorious.

The Maya were a collection of people clustered in city-states. What united them was an idea. For the Maya the world of ordinary living and the Otherworld populated by gods, ancestors, and monstrous things, were equally real. There existed three regions, intricately bound together: the heavens, the earth, and the waters of the Underworld.

United States foreign policy has changed dramatically from George Washington's day. Although Americans always pay attention to the advice of their revered founder, the world is of course not the same. The many people that shape American foreign policy today accept the fact that the United States is a member of a world community that cannot afford to ignore the importance of getting along.

In the past 25 years archaeologists have learned to read what the Mayas wrote. Today we know the names of kings and queens, how they lived, and when they died, transforming our view of Maya culture.

Just as developing a coherent foreign policy is problematic in these post-Cold War days, so is the question of defending the country against possible danger from outside its borders. The avoidance of war, as indicated by the 1947 name change from "Department of War" to "Department of Defense" today holds the highest priority, and the hope that the United States can play a role in limiting violent upheavals around the world is reflected in both its foreign and military policies.

It is impossible to know the exact number of American colonists who favored or opposed independence. This section discusses attitudes toward the American Revolution in the colonies

Until the 20th century the country abided by the laissez-faire policy, which required a free market with little intervention from government. With the Great Depression came Keynesian economics, or the opposite belief that the government should manage the economy. Today, United States economic policy lies somewhere in between åÑ government should regulate and sometimes manage, but should allow a free market whenever possible. Political and business leaders disagree on how much control is enough.

Ready to fight at a moment's notice, minutemen began fighting early in the American Revolution. Their efforts at Lexington and Concord inspired many patriots to take up arms against Britain.

The Inca called their empire Tahuantinsuyu, or Land of the Four Quarters. It stretched 2,500 miles from Quito, Ecuador, to beyond Santiago, Chile. Within its domain were rich coastal settlements, high mountain valleys, rain-drenched tropical forests and the driest of deserts. The Inca controlled perhaps 10 million people, speaking a hundred different tongues. It was the largest empire on earth at the time. Yet when Pizarro executed its last emperor, Atahualpa, the Inca Empire was only 50 years old.
