Question: Which documentary premiered first, The Civil War or Prince Among Slaves?
Context: Contraband was a term commonly used in the United States military during the American Civil War to describe a new status for certain escaped slaves or those who affiliated with Union forces.  The Army (and the United States Congress) determined that the US would not return escaped slaves who went to Union lines and classified them as contraband.  They used many as laborers to support Union efforts and soon began to pay them wages.  The former slaves set up camps near Union forces, and the Army helped support and educate both adults and children among the refugees.  Thousands of men from these camps enlisted in the United States Colored Troops when recruitment started in 1863.  At war's end, more than 100 contraband camps existed in the South, including the Freedmen's Colony of Roanoke Island, where 3500 former slaves worked to develop a self-sufficient community. "Roll, Jordan, Roll" (Roud 6697), also "Roll, Jordan", is a spiritual written by Charles Wesley in the 18th century which became well-known among slaves in the United States during the 19th century.  Appropriated as a coded message for escape, by the end of the American Civil War it had become known through much of the eastern United States.  In the 20th century it helped inspire blues, and it remains a staple in gospel music. Edisto Island during the American Civil War was the location of a number of minor engagements and for a time of a large colony of African-American escaped former slaves during the American Civil War (1861–1865).  Edisto Island was largely abandoned by planters in November 1861 and in December 1861, escaped slaves began setting up their own refugee camps there.  In January 1862, armed African Americans from the island and Confederate forces clashed and a Confederate raid in reprisal killed a small number of unarmed African Americans.  In February, Union forces were stationed on the island to develop it as a staging area for future campaigns against Charleston, twenty-five miles away, as well as to protect the colony, which would eventually number thousands of African Americans.  As Union forces took control of the island, a number of skirmishes occurred, but Confederates withdrew.  In June, most of the Union troops left the island in a campaign, which culminated in the Battle of Secessionville.  In July, the remaining troops withdrew, and the colony was removed to St. Helena Island.  For the rest of the war, a small number of escaped slaves and plantation owners remained and farmed the island, but it was largely abandoned.  Near the end of the war, the island was again used as a location of colonies of freed slaves. English Landing Park is located along the Missouri river in Parkville, Missouri, United States.  The area the park now sits were once just low water areas of the Missouri River.  It includes a 3-mile jogging/biking trail that follows the river's edge, several shelters for picnics, a soccer field, a baseball diamond, volleyball courts, 2 playgrounds (one for small kids and one for bigger kids).  Recently, a small 9-hole Frisbee golf course has been added around the jogging/biking trail.  There is also a busy set of train tracks that runs along the length of the park.  The area of present-day English Landing Park was bought from the English Brothers by Colonel George S. Park in 1838, who was a veteran of the Texas war of independence.  He purchased a riverboat landing from them as well, and that riverboat landing as well as the present-day park became a civil war port of call for slave trade.  The Power Plant Restaurant, which sits right next to the rail road tracks at the entrance to the park, was built in the mid-19th century as a coal-fired twin-boiler power plant that fed the entire city.  The city itself was founded by Colonel Park in 1844 and by 1850 he had built warehouses and a large stone hotel.  In 1853 he established one of Platte County's earliest newspapers, The Industrial Luminary.  Parkville itself did not become a Civil War battlefield, but there was still mass genocide as numerous slaves tried desperately to escape across the river into Kansas for freedom.  These slaves were buried in three large but unmarked cemeteries in the present-day Misty Woods subdivision.  After the Civil War, the port and the riverboat landing were all but abandoned and the area slowly changed from a bustling port city to what is present-day Parkville.

The Radical Republicans were a faction of American politicians within the Republican Party of the United States from around 1854 (before the American Civil War) until the end of Reconstruction in 1877.  They called themselves "Radicals" and were opposed during the War by the Moderate Republicans (led by President Abraham Lincoln), by the conservative Republicans, and the largely pro-slavery and later anti-Reconstruction Democratic Party, as well as by conservatives in the South and liberals in the North during Reconstruction.  Radicals led efforts after the war to establish civil rights for former slaves and fully implement emancipation.  After weaker measures resulted in 1866 violence against former slaves in the rebel states, Radicals pushed the 14th Amendment and statutory protections through Congress.  They disfavored allowing ex-Confederates officers to retake political power in the south, and emphasized equality, civil rights, and voting rights for the "freedmen" (recently freed slaves). Eric J.
