The law of the United States consists of many levels of codified and uncodified forms of law, of which the most important is the United States Constitution, the foundation of the federal government of the United States. The Constitution sets out the boundaries of federal law, which consists of constitutional acts of Congress, constitutional treaties ratified by Congress, constitutional regulations promulgated by the executive branch, and case law originating from the federal judiciary.
The Constitution and federal law are the supreme law of the land, thus preempting conflicting state and territorial laws in the fifty U.S. states and in the territories. However, the scope of federal preemption is limited, because the scope of federal power is itself rather limited. In the unique dual-sovereign system of American federalism (actually tripartite because of the presence of Indian reservations), states are the plenary sovereigns, while the federal sovereign possesses only the limited supreme authority enumerated in the Constitution. Indeed, states may grant their citizens broader rights than the federal Constitution as long as they do not infringe on any federal constitutional rights. Thus, most U.S. law (especially the actual "living law" of contract, tort, property, criminal, and family law experienced by the majority of citizens on a day-to-day basis) consists primarily of state law, which can and does vary greatly from one state to the next.
At both the federal and state levels, the law of the United States was originally largely derived from the common law system of English law, which was in force at the time of the Revolutionary War. However, U.S. law has diverged greatly from its English ancestor both in terms of substance and procedure, and has incorporated a number of civil law innovations.

“On the whole, yes, I would rather be the Chief Justice of the United States, and a quieter life than that which becomes at the White House is more in keeping with the temperament, but when taken into consideration that I go into history as President, and my children and my children’s children are the better placed on account of that fact, I am inclined to think that to be President well compensates one for all the trials and criticisms he has to bear and undergo.”
—William Howard Taft (1857–1930)
“Nor has science sufficient humanity, so long as the naturalist overlooks the wonderful congruity which subsists between man and the world; of which he is lord, not because he is the most subtile inhabitant, but because he is its head and heart, and finds something of himself in every great and small thing, in every mountain stratum, in every new law of color, fact of astronomy, or atmospheric influence which observation or analysis lay open.”
—Ralph Waldo Emerson (1803–1882)
“I consider, then, the power to annul a law of the United States, assumed by one state, incompatible with the existence of the Union, contradicted expressly by the letter of the Constitution, unauthorized by its spirit, inconsistent with every principle on which it was founded, and destructive of the great object for which it was formed.”
—Andrew Jackson (1767–1845)
“Europe and the U.K. are yesterday’s world. Tomorrow is in the United States.”
—R.W. “Tiny” Rowland (b. 1917)
“In it he proves that all things are true and states how the truths of all contradictions may be reconciled physically, such as for example that white is black and black is white; that one can be and not be at the same time; that there can be hills without valleys; that nothingness is something and that everything, which is, is not. But take note that he proves all these unheard-of paradoxes without any fallacious or sophistical reasoning.”
—Savinien Cyrano De Bergerac (1619–1655)
