End of slavery in the United States in the context of "Third Party System"

Abraham Lincoln (February 12, 1809 – April 15, 1865) was the 16th president of the United States, serving from 1861 until his assassination in 1865. He led the United States through the American Civil War, defeating the Confederate States and playing a major role in the abolition of slavery.

Lincoln was born into poverty in Kentucky and raised on the frontier. He was self-educated and became a lawyer, Illinois state legislator, and U.S. representative. Angered by the Kansas–Nebraska Act of 1854, which opened the territories to slavery, he became a leader of the new Republican Party. He reached a national audience in the 1858 Senate campaign debates against Stephen A. Douglas. Lincoln won the 1860 presidential election, prompting a majority of slave states to begin to secede and form the Confederate States. A month after Lincoln assumed the presidency, Confederate forces attacked Fort Sumter, starting the Civil War.

The Statue of Liberty (Liberty Enlightening the World; French: La Liberté éclairant le monde) is a colossal neoclassical sculpture of a robed and crowned female on Liberty Island in New York Harbor, within New York City. The copper-clad statue, a gift to the United States from the people of France, was designed by French sculptor Frédéric Auguste Bartholdi, and its metal framework built by Gustave Eiffel. The statue was dedicated on October 28, 1886.

The statue is a figure of a classically draped woman, likely inspired by the Roman goddess of liberty, Libertas. In a contrapposto pose, she holds a torch above her head with her right hand, and in her left hand carries a tabula ansata inscribed JULY IV MDCCLXXVI (July 4, 1776, in Roman numerals), the date of the U.S. Declaration of Independence. With her left foot she steps on a broken chain and shackle, commemorating the national abolition of slavery following the American Civil War. After its dedication, the statue became an icon of freedom and of the United States, seen as a symbol of welcome to immigrants arriving by sea.

Abraham Lincoln's tenure as the 16th president of the United States began on March 4, 1861, and ended upon his death on April 15, 1865, 42 days into his second term. Lincoln, the first Republican president, successfully presided over the Union victory in the American Civil War, which dominated his presidency and resulted in the end of slavery in the United States. He was succeeded by Vice President Andrew Johnson.

Lincoln took office following the 1860 presidential election, in which he won a plurality of the popular vote in a four-candidate field. Almost all of Lincoln's votes came from the Northern United States, as the Republicans held little appeal to voters in the Southern United States. A former Whig, Lincoln ran on a political platform opposed to the expansion of slavery in the territories. His election served as the immediate impetus for the outbreak of the Civil War. After being sworn in as president, Lincoln refused to accept any resolution that would result in Southern secession from the Union. The Civil War began weeks into Lincoln's presidency with the Confederate attack on Fort Sumter, a federal installation located within the boundaries of the Confederacy.

The Emancipation Proclamation, officially Proclamation 95, was a presidential proclamation and executive order issued by United States president Abraham Lincoln on January 1, 1863, during the American Civil War. The Proclamation changed the legal status of more than 3.5 million enslaved African Americans in the secessionist Confederate states from enslaved to free. As soon as slaves escaped the control of their enslavers, either by fleeing to Union lines or through the advance of federal troops, they were permanently free. In addition, the Proclamation allowed for former slaves to "be received into the armed service of the United States". The Emancipation Proclamation played a significant part in the end of slavery in the United States.

On September 22, 1862, Lincoln issued the Preliminary Emancipation Proclamation. Its third paragraph begins:

Juneteenth, officially Juneteenth National Independence Day, is a federal holiday in the United States. It is celebrated annually on June 19 to commemorate the end of slavery in the United States. The holiday's name, first used in the 1890s, is a portmanteau of June and nineteenth, referring to June 19, 1865, the day when Major General Gordon Granger ordered the final enforcement of the Emancipation Proclamation in Texas at the end of the American Civil War.

In the Civil War period, slavery came to an end in various areas of the United States at different times. Many enslaved Southerners escaped, demanded wages, stopped work, or took up arms against the Confederacy of slave states. In January 1865, Congress proposed the Thirteenth Amendment to the United States Constitution for the national abolition of slavery. By June 1865, almost all of the enslaved population had been freed by the victorious Union Army or by state abolition laws. When the national abolition amendment was ratified in December, the remaining enslaved people in Delaware and in Kentucky were freed.

Southern Maryland, also referred to as SoMD, is a geographical, cultural and historic region in Maryland composed of the state's southernmost counties on the Western Shore of the Chesapeake Bay. According to the state of Maryland, the region includes all of Calvert, Charles, and St. Mary's counties and the southern portions of Anne Arundel and Prince George's counties. It is largely coterminous with the region of Maryland that is part of the Washington metropolitan area. Portions of the region are also part of the Baltimore Metropolitan Area and the California-Lexington Park Metropolitan Statistical Area. As of the 2020 Census, the region had a population of 373,177. The largest community in Southern Maryland is Waldorf, with a population of 81,410 as of the 2020 Census.

Initially inhabited by the indigenous Piscataway people, the first European settlement in Southern Maryland (and the state as a whole) was established in St. Mary's City in 1634. While the settlement was intended to be a Catholic refuge, religious strife was prominent in Maryland's early years. The passage of the Maryland Toleration Act in 1649 resulted in St. Mary's City being cited as the birthplace of religious freedom in North America. The area developed an agricultural economy based on tobacco with labor sourced from indentured servants and slaves. The War of 1812 saw military action in the region during the British campaign to capture Washington, while the American Civil War saw the end of slavery in Maryland and John Wilkes Booth fleeing through the region following the Assassination of Abraham Lincoln. Much of the area remains rural with agriculture still playing a large role in the region's economy. Despite this, the region has seen large suburban growth and development in the late 20th and early 21st centuries as urban sprawl from nearby Washington, D.C., expands southward.
