Long before fighting with guns started in the Civil War (1861–1865), Americans fought with words and ideas. As this issue shows, nearly all the disagreements involved slavery, and efforts to compromise never permanently eliminated the threat that slavery presented to the nation’s united future.
When the Constitutional Convention opened in Philadelphia in the summer of 1787, the delegates faced a problem: The country’s regional differences made agreeing on how “to form a more perfect union” difficult. The southern states’ fertile land and warm weather were ideal for growing large agricultural crops, which depended on an enslaved labor force. The northern states’ rocky soil and cold winters made them rely on occupations in trade and industry. And most northern states had started to abolish slavery.
After four months of heated debate behind closed doors, the delegates shared the Constitution with the American people. In order to come to an agreement about how to organize the new federal government, the delegates had reached compromises over slavery.

Eye in the Sky
An interview with Joe Piotrowski
Airborne Animals
Humans have taken to the skies in balloons, gliders, and airplanes-but we're not alone among the clouds. Animals of all sorts have evolved to harness wind power.
TAKING OFF
The Wright brothers expected airplanes to “take off,” but even they might be amazed at the way the airline industry has become big business. In the past, it was expensive to send something by plane.
GROWTH OF AN INDUSTRY
After their historic flight at Kitty Hawk in 1903, Wilbur and Orville Wright returned to Dayton, Ohio. They spent the next few years making adjustments and building additional versions of their powered aircraft in their bicycle shop.
WHY KITTY HAWK?
The Wright brothers searched carefully for the best place to test their gliders and flying machines. Their main concern was for good, steady winds. But they also hoped to find a remote location to allow them to perform tests away from the public eye.
Two Brothers From Ohio
Most people do not realize that the Wright brothers—Wilbur, born in 1867, and Orville, born in 1871—performed various scientific experiments before inventing their aircraft. For as long as anyone in their hometown of Dayton, Ohio, could remember, the Wright boys had worked on mechanical projects.
A Helping Hand
May 6, 1896. A group of people who had gathered beside the Potomac River, just south of the U.S. capital, grew quiet. Then, it erupted in cheers as a small, unmanned aircraft took to the skies and flew for more than half a mile. The flight came seven years before the Wright brothers’ first manned, powered flight. The inventor of the aircraft was Dr. Samuel Pierpont Langley.
THE IDEA MEN
People dreamed of flying thousands of years before the Wright brothers found success near Kitty Hawk, North Carolina. These dreamers, such as Leonardo da Vinci, studied birds flying and imagined how humans might do the same—if only they had wings. Other men developed a more hands-on approach to the topic. Early inventors made wings of cloth, glue, and feathers and tied these creations to their arms in an attempt to imitate nature.
Da Vinci's 4 Designs
Have you ever wondered how a bird flies? Leonardo da Vinci (1452–1519) did. He thought that understanding how a bird flies would provide the key to human flight. So, what did da Vinci learn from birds?
Silken Wings
Seven hundred years before the Wright brothers began experimenting with human flight, the Chinese had already mastered its secrets—with kites.
