Passage: Columbia, formerly Wright's Ferry, is a borough (town) in Lancaster County, Pennsylvania, 28 miles (45 km) 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.

Passage: Born to an aristocratic family in Ithaca, Metaxas took part in the Greco-Turkish War of 1897 and the Balkan Wars (1912–13), quickly rising through the ranks of the Hellenic Army. A royalist during the National Schism, Metaxas unsuccessfully opposed Prime Minister Eleftherios Venizelos and Greece's entry in World War I; as a result, he was exiled to Corsica in 1917. On his return, Metaxas moved into politics and founded the Freethinkers' Party, but had only limited success under the Hellenic Republic. The Greek monarchy was restored in 1935, and Metaxas was appointed Prime Minister in April 1936. On 4 August 1936, with the support of King George II, Metaxas initiated a self-coup and established an authoritarian, nationalist and anti-communist regime.
