During the early 20th century, groundbreaking technology revolutionized transportation both on the ground and in the sky, with new motors making automobiles and airplanes a reality in the 1910s.

Next to Joseph Smith, Brigham Young is one of the best known Mormon leaders and perhaps the most important.

Antietam is remembered as one of the major turning points of the Civil War, but it is often overlooked that the bloody battle only represented the climactic culmination of a 3-week campaign that saw George McClellan cautiously pull a fragmented Union army together and begin tracking Robert E.

Rosecrans, began digging in around the city and waiting for reinforcements to arrive.
