full_context: Document 1: Andrew Johnson National Historic Site: The cemetery also includes the interments of Johnson's wife, Eliza McCardle Johnson, and son Brigadier General Robert Johnson Henderson. David T. Patterson, a United States Senator from Tennessee, and his son Andrew J. Patterson, who was instrumental in securing historic designation for the Greeneville properties associated with Andrew Johnson, were among others buried in the cemetery. The site was authorized by Congress as a U.S. National Monument in 1935, established on April 27, 1942, and redesignated a National Historic Site on December 11, 1963.
Document 2: Sarah Childress Polk: Sarah Polk ("née" Childress; September 4, 1803 – August 14, 1891) was the First Lady of the United States from 1845 to 1849. She was the wife of the 11th President of the United States, James K. Polk.
Document 3: McKamie Farmhouse: The McKamie Farmhouse was a farmhouse located in Waxhaws, North Carolina, and is one of two disputed birthplaces of Andrew Jackson, the other being in South Carolina.
Document 4: United States Army: The War of 1812, the second and last American war against the United Kingdom, was less successful for the U.S. than the Revolution and Northwest Indian War against natives had been, though it ended on a high note for Americans as well. After the taking control of Lake Erie in 1813, the Americans were able to seize parts of western Upper Canada, burn York and defeat Tecumseh, which caused his Indian Confederacy to collapse. Following ending victories in the province of Upper Canada, which dubbed the U.S. Army "Regulars, by God!", British troops were able to capture and burn Washington. The regular army, however, proved they were professional and capable of defeating the British army during the invasions of Plattsburgh and Baltimore, prompting British agreement on the previously rejected terms of a status quo ante bellum. Two weeks after a treaty was signed (but not ratified), Andrew Jackson defeated the British in the Battle of New Orleans and became a national hero. Per the treaty both sides returned to the status quo with no victor.
Document 5: War of 1812: The War of 1812 was a conflict fought between the United States, the United Kingdom, and their respective allies from June 1812 to February 1815. Historians in Britain often see it as a minor theatre of the Napoleonic Wars; in the United States and Canada, it is seen as a war in its own right.
Document 6: American Revolution: The Continental Army forced the British out of Boston in 1776, but the British captured and held New York City for the duration of the war. The British blockaded ports and captured other cities for brief periods, but they failed to defeat Washington's forces. The Patriots unsuccessfully attempted to invade Canada during the winter of 1775 -- 76, but they captured a British army at the Battle of Saratoga in late 1777, and the French entered the war as allies of the United States as a result. The war later turned to the American South where the British under the leadership of Charles Cornwallis captured an army at South Carolina but failed to enlist enough volunteers from Loyalist civilians to take effective control of the territory. A combined American -- French force captured a second British army at Yorktown in 1781, effectively ending the war in the United States. The Treaty of Paris in 1783 formally ended the conflict, confirming the new nation's complete separation from the British Empire. The United States took possession of nearly all the territory east of the Mississippi River and south of the Great Lakes, with the British retaining control of Canada and Spain taking Florida.
Document 7: Results of the War of 1812: In the Southeast, Andrew Jackson's destruction of Britain's allies, the Creek Indians at the Battle of Horseshoe Bend in 1814, ended the threat of Native American hostilities in that region. It opened vast areas in Georgia and Alabama for settlement as plantations and farmlands. The U.S. occupied all of West Florida during the war and in 1819 purchased the rest of Florida from Spain, thus preventing the Spanish from arming hostile tribes there. Creek Indians who escaped to Spanish Florida joined the Seminoles there, and put up a long resistance known as the Seminole Wars.
Document 8: Daniel Smith Donelson: Daniel Smith Donelson (June 23, 1801 – April 17, 1863) was a Tennessee politician and soldier. The historic river-port of Fort Donelson was named for him as a Brigadier in the Tennessee militia, early in the American Civil War, in which he went on to serve as a Confederate general, notably at Perryville and Stones River. He was the nephew of America's seventh president, Andrew Jackson.
Document 9: War of 1812: The War of 1812 (1812 -- 1815) was a conflict fought between the United States, the United Kingdom and their respective allies. Historians in Britain often see it as a minor theater of the Napoleonic Wars; in the United States and Canada, it is seen as a war in its own right.
Document 10: Andrew Johnson National Cemetery: The Andrew Johnson National Cemetery is a United States National Cemetery on the grounds of the Andrew Johnson National Historic Site in Greeneville, Tennessee. Established in 1906, the cemetery was built around the resting place of Andrew Johnson, the 17th President of the United States, and holds more than two thousand graves.
Document 11: War of 1812: The War of 1812 (1812 -- 1815) was a conflict fought between the United States, the United Kingdom, and their respective allies. Historians in Britain often see it as a minor theatre of the Napoleonic Wars; in the United States and Canada, it is seen as a war in its own right.
Document 12: American Revolution: The Continental Army forced the redcoats out of Boston in March 1776, but that summer the British captured and held New York City and its strategic harbor for the duration of the war. The Royal Navy blockaded ports and captured other cities for brief periods, but they failed to defeat Washington's forces. The Patriots unsuccessfully attempted to invade Canada during the winter of 1775 -- 76, but successfully captured a British army at the Battle of Saratoga in October 1777. France now entered the war as an ally of the United States with a large army and navy that threatened Britain itself. The war turned to the American South where the British under the leadership of Charles Cornwallis captured an army at Charleston, South Carolina in early 1780 but failed to enlist enough volunteers from Loyalist civilians to take effective control of the territory while fighting partisans. A combined American -- French force captured a second British army at Yorktown in the fall of 1781, effectively ending the war in North America. The Treaty of Paris, signed September 3, 1783, formally ended the conflict, confirming the new nation's complete separation from the British Empire. The United States took possession of nearly all the territory east of the Mississippi River and south of the Great Lakes, with the British retaining control of Canada and Spain taking Florida.
Document 13: Rachel Jackson: Rachel Jackson ("née" Donelson; June 15, 1767 – December 22, 1828) was the wife of Andrew Jackson, the 7th President of the United States. She lived with him at their home at The Hermitage, where she died just days after his election and before his inauguration in 1829—therefore she never served as First Lady, a role assumed by her niece, Emily Donelson.
Document 14: Abigail Adams: Abigail Adams (née Smith; November 22, (O.S. November 11) 1744 -- October 28, 1818) was the closest advisor and wife of John Adams, as well as the mother of John Quincy Adams. She is sometimes considered to have been a Founder of the United States, and is now designated as the first Second Lady and second First Lady of the United States, although these titles were not used at the time.
Document 15: Mary Harrison McKee: Mary Scott Harrison McKee (April 3, 1858 – October 28, 1930) was the only daughter of President Benjamin Harrison and his wife Caroline Scott Harrison. After her mother died in 1892, McKee served as her father's "de facto" First Lady for the remainder of his term.
