Union (American Civil War) in the context of "US"

The Republican Party, also known as the Grand Old Party (GOP), is a conservative and right-wing political party in the United States. It emerged as the main rival of the Democratic Party in the 1850s, and the two parties have dominated American politics since then.

The Republican Party was founded in 1854 by anti-slavery activists opposing the Kansas–Nebraska Act and the expansion of slavery into U.S. territories. It rapidly gained support in the North, drawing in former Whigs and Free Soilers. Abraham Lincoln's election in 1860 led to the secession of Southern states and the outbreak of the American Civil War. Under Lincoln and a Republican-controlled Congress, the party led efforts to preserve the Union, defeat the Confederacy, and abolish slavery. During the Reconstruction era, Republicans sought to extend civil rights protections to freedmen, but by the late 1870s the party shifted its focus toward business interests and industrial expansion. In the late 19th and early 20th centuries, it dominated national politics, promoting protective tariffs, infrastructure development, and laissez-faire economic policies, while navigating internal divisions between progressive and conservative factions. The party's support declined during the Great Depression, as the New Deal coalition reshaped American politics. Republicans returned to national power with the 1952 election of Dwight D. Eisenhower, whose moderate conservatism reflected a pragmatic acceptance of many New Deal-era programs.

The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 states and a federal capital district, Washington, D.C. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclave of Alaska in the northwest and the archipelago of Hawaii in the Pacific Ocean. The United States also asserts sovereignty over five major island territories and various uninhabited islands in Oceania and the Caribbean. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 340 million.

Paleo-Indians first migrated from North Asia to North America over 12,000 years ago, and formed various civilizations. Spanish colonization established Spanish Florida in 1513, the first European colony in what is now the continental United States. British colonization followed with the 1607 settlement of Virginia, the first of the Thirteen Colonies. Enslavement of Africans was practiced in all colonies by 1770 and supplied most of the labor for the Southern Colonies' plantation economy. Clashes with the British Crown over taxation and lack of parliamentary representation sparked the American Revolution, leading to the Declaration of Independence on July 4, 1776. Victory in the 1775–1783 Revolutionary War brought international recognition of U.S. sovereignty and fueled westward expansion, dispossessing native inhabitants. As more states were admitted, a North–South division over slavery led the Confederate States of America to attempt secession and fight the Union in the 1861–1865 American Civil War. With the United States' victory and reunification, slavery was abolished nationally. By 1900, the country had established itself as a great power, a status solidified after its involvement in World War I. Following Japan's attack on Pearl Harbor in 1941, the U.S. entered World War II. Its aftermath left the U.S. and the Soviet Union as rival superpowers, competing for ideological dominance and international influence during the Cold War. The Soviet Union's collapse in 1991 ended the Cold War, leaving the U.S. as the world's sole superpower.

New Jersey is a state located in both the Mid-Atlantic and Northeastern regions of the United States. Located at the geographic hub of the heavily urbanized Northeast megalopolis, it is bordered to the northwest, north, and northeast by New York State; on its east, southeast, and south by the Atlantic Ocean; on its west by the Delaware River and Pennsylvania; and on its southwest by Delaware Bay and Delaware. At 7,354 square miles (19,050 km), New Jersey is the fifth-smallest state in land area. According to a 2024 U.S. Census Bureau estimate, it is the 11th-most populous state, with over 9.5 million residents, its highest estimated count ever. The state capital is Trenton, and the state's most populous city is Newark. New Jersey is the only U.S. state in which every county is deemed urban by the U.S. Census Bureau. It is the most densely populated U.S. state.

New Jersey was first inhabited by Paleo-Indians as early as 13,000 BC. The Lenape were the dominant Indigenous group when Europeans arrived in the early 17th century, and they were subdivided into dialectal groups such as the Munsee, in the north, and the Unami and the Unalachtigo, elsewhere. Dutch and Swedish colonists founded the first European settlements in the state, with the British later seizing control of the region and establishing the Province of New Jersey, named after Jersey. The colony's fertile lands and relative religious tolerance drew a large and diverse population. New Jersey was among the Thirteen Colonies that supported the American Revolution, hosting several pivotal battles and military commands in the American Revolutionary War earning the title, "Crossroads of the American Revolution." New Jersey remained in the Union during the American Civil War and provided troops, resources, and military leaders in support of the Union Army. After the war, the state emerged as a major manufacturing center and a leading destination for immigrants, helping drive the Industrial Revolution in the U.S. New Jersey was the site of many industrial, technological, and commercial innovations. Many prominent Americans associated with New Jersey have proven influential nationally and globally, including in academia, advocacy, business, entertainment, government, military, non-profit leadership, and other fields.

The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from the Union to preserve African American slavery, which they saw as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North.

Decades of controversy over slavery came to a head when Abraham Lincoln, a Republican who opposed slavery's expansion, won the 1860 presidential election. Seven Southern slave states responded to Lincoln's victory by seceding from the United States and forming the Confederacy. The Confederacy seized US forts and other federal assets within its borders. The war began on April 12, 1861, when the Confederacy bombarded Fort Sumter in South Carolina. A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after the war began and, led by its president, Jefferson Davis, the Confederacy asserted control over a third of the US population in eleven states. Four years of intense combat, mostly in the South, ensued.

The Confederate States of America (CSA), also known as the Confederate States (C.S.), the Confederacy, or the South, was an unrecognized breakaway republic in the Southern United States from 1861 to 1865. It comprised eleven U.S. states that declared secession: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. These states fought against the United States during the American Civil War.

With Abraham Lincoln's election as President of the United States in 1860, eleven southern states believed their slavery-dependent plantation economies were threatened, and seven initially seceded from the United States. The Confederacy was formed on February 8, 1861, by South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas. They adopted a new constitution establishing a confederation government of "sovereign and independent states". The federal government in Washington D.C. and states under its control were known as the Union.

Texas (/ˈtɛksəs/ TEK-səss) is the most populous state in the South Central region of the United States. It borders Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and an international border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south and southwest. Texas has a coastline on the Gulf of Mexico to the southeast. Covering 268,596 square miles (695,660 km) and with over 31 million residents as of 2024, it is the second-largest U.S. state by both area and population. Texas is nicknamed the "Lone Star State" for the single star on its flag, symbolic of its former status as an independent country, the Republic of Texas.

Spain was the first European country to claim and control Texas. Following a short-lived colony controlled by France, Mexico controlled the land until 1836 when Texas won its independence, becoming the Republic of Texas. In 1845, Texas joined the United States of America as the 28th state. The state's annexation set off a chain of events that led to the Mexican–American War in 1846. Following victory by the United States, Texas remained a slave state until the American Civil War, when it declared its secession from the Union in early 1861 before officially joining the Confederate States on March 2. After the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation.
