Lincoln was worried about Kentucky, Missouri, Maryland, and Delaware because they were all border states during the civil war. He was worried that they would transform into complete slave states. If they did, the north wouldn’t have much more land and the north would have lost the civil war. He wanted to contain them.
According to political scientist Brian R. Dirck, the most famous executive order was by President Abraham Lincoln, when he issued the Emancipation Proclamation on January 1, 1863: The Emancipation Proclamation was an executive order, itself a rather unusual thing in those days.
Johann Gutenberg’s invention of the printing press around 1448 had a significant impact on the spread of ideas in Europe and beyond. Printing technology traveled quickly across Europe and, at a time of great religious change, played a key role in the success of the Protestant Reformation. Reformation leader Martin Luther could only preach to a small number of people, but the printed word could spread his message to thousands more
The printing press drastically cut the cost of producing books and other printed materials. Prior to Gutenberg’s invention, the only way of making multiple copies of a book was to copy the text by hand, an laborious and intensely time-consuming occupation usually performed by monks. The materials involved were also costly: Monks wrote on treated skins, known as vellum, and a single copy of the Bible could require 300 sheepskins or 170 calfskins. Printing onto paper made copying cheaper and faster.
