New Jersey becomes the first U.S. state to ratify the Bill of Rights.

The United States Bill of Rights comprises the first ten amendments to the United States Constitution. Proposed following the often bitter 178788 debate over the ratification of the Constitution and written to address the objections raised by Anti-Federalists, the Bill of Rights amendments add to the Constitution specific guarantees of personal freedoms and rights, clear limitations on the government's power in judicial and other proceedings, and explicit declarations that all powers not specifically granted to the federal government by the Constitution are reserved to the states or the people. The concepts codified in these amendments are built upon those in earlier documents, especially the Virginia Declaration of Rights (1776), as well as the Northwest Ordinance (1787), the English Bill of Rights (1689), and Magna Carta (1215).Largely because of the efforts of Representative James Madison, who studied the deficiencies of the Constitution pointed out by anti-federalists and then crafted a series of corrective proposals, Congress approved twelve articles of amendment on September 25, 1789, and submitted them to the states for ratification. Contrary to Madison's proposal that the proposed amendments be incorporated into the main body of the Constitution (at the relevant articles and sections of the document), they were proposed as supplemental additions (codicils) to it. Articles Three through Twelve were ratified as additions to the Constitution on December 15, 1791, and became Amendments One through Ten of the Constitution. Article Two became part of the Constitution on May 5, 1992, as the Twenty-seventh Amendment. Article One is still pending before the states.

Although Madison's proposed amendments included a provision to extend the protection of some of the Bill of Rights to the states, the amendments that were finally submitted for ratification applied only to the federal government. The door for their application upon state governments was opened in the 1860s, following ratification of the Fourteenth Amendment. Since the early 20th century both federal and state courts have used the Fourteenth Amendment to apply portions of the Bill of Rights to state and local governments. The process is known as incorporation.There are several original engrossed copies of the Bill of Rights still in existence. One of these is on permanent public display at the National Archives in Washington, D.C.

New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware River and Pennsylvania; and on the southwest by Delaware Bay and the state of Delaware. At 7,354 square miles (19,050 km2), New Jersey is the fifth-smallest state based on land area, but with close to 9.3 million residents, is the 11th-most populous and the most densely populated. New Jersey's state capital is Trenton, while the state's most populous city is Newark. With the sole exception of Warren County, all counties in the state lie within the combined statistical areas of New York City or Philadelphia; consequently, the state's largest metropolitan area falls within Greater New York.

New Jersey was first inhabited by Native Americans for at least 2,800 years, with the Lenape being the dominant group when Europeans arrived in the early 17th century. Dutch and the Swedish colonists founded the first European settlements in the state. The English later seized control of the region and established the Province of New Jersey, after the largest of the Channel Islands, Jersey. The colony's fertile lands and relative religious tolerance drew a large and diverse population. New Jersey was among the Thirteen Colonies that opposed Great Britain, hosting numerous pivotal battles and military commands in the American Revolutionary War. The state remained in the Union during the American Civil War, and thereafter became a major center of manufacturing and immigration; it helped drive the nation's Industrial Revolution, and became the site of numerous technological and commercial innovations into the mid 20th century.

New Jersey's central location in the Northeast megalopolis fueled its rapid growth and suburbanization in the second half of the 20th century. At the turn of the 21st century, its economy increasingly diversified, with major sectors including biotechnology, pharmaceuticals, specialized agriculture, and informational technology. New Jersey remains a major destination for immigrants, with one of the most multicultural populations in the U.S. Echoing historic trends, the state has increasingly re-urbanized, with growth in the cities outpacing the suburbs since 2008. New Jersey is one of the wealthiest states in the U.S., with the second highest median household income in 2017. Almost one-tenth of all households, or over 323,000 of 3.3 million, are millionaires, the highest rate per capita in the country. New Jersey's public school system consistently ranks at or among the top of all U.S. states.
