PROBLEM: Passage: Alabama was central to the Civil War, with the secession convention at Montgomery, birthplace of the Confederacy, inviting other states to form a Southern Republic, during JanuaryMarch 1861, and develop constitutions to legally run their own affairs. The 1861 Alabama Constitution granted citizenship to current U.S. residents, but prohibited import duties (tariffs) on foreign goods, limited a standing military, and as a final issue, opposed emancipation by any nation, but urged protection of African slaves, with trial by jury, and reserved the power to regulate or prohibit the African slave trade. The secession convention invited all slaveholding states to secede, but only 7 Cotton States of the Lower South formed the Confederacy with Alabama, while the majority of slave states were in the Union and voted to make U.S. slavery permanent by passing the Corwin Amendment, signed by President Buchanan and backed by President Lincoln on March 4, 1861.
Link Information: Beginning February 4, 1861, representatives from Alabama, Georgia, Florida, Louisiana, Mississippi, and South Carolina met in Montgomery, host of the Southern Convention, to form the Confederate States of America. Question: What dates did the secession convention occur in Alabama?

SOLUTION: Answer: Beginning February 4, 1861

PROBLEM: Passage: Columbia, formerly Wright's Ferry, is a borough (town) in Lancaster County, Pennsylvania, 28 miles (45km) southeast of Harrisburg on the east (left) bank of the Susquehanna River, across from Wrightsville and York County and just south of U.S. Route 30. The settlement was founded in 1726 by Colonial English Quakers from Chester County led by entrepreneur and evangelist John Wright. Establishment of the eponymous Wright's Ferry, the first commercial Susquehanna crossing in the region, inflamed territorial conflict with neighboring Maryland but brought growth and prosperity to the small town, which was just a few votes shy of becoming the new United States' capital. Though besieged for a short while by Civil War destruction, Columbia remained a lively center of transport and industry throughout the 19th century, once serving as a terminus of the Pennsylvania Canal. Later, however, the Great Depression and 20th-century changes in economy and technology sent the borough into decline. It is notable today as the site of one of the world's few museums devoted entirely to horology.
Link Information: As of the 2010 census, the population was 519,445. Question: What is the current population of the county where Columbia, PA is located?

SOLUTION: Answer: 519,445
