The second group of southern states seceded after the attack at Fort Sumter. Four additional states left at this time. These states left because they had concerns about what would happen to slavery now that the fighting had begun. They waited until the Civil War began before leaving the Union.’!!!!!!!!!!
Banning labor unions stopped the ability for workers to organize union strikes, which stopped production until the management of the factory gave more rights to the workers.

The technological and industrial history of the United States describes the United States' emergence as one of the most technologically advanced nations in the world. The availability of land and literate labor, the absence of a landed aristocracy, the prestige of entrepreneurship, the diversity of climate and a large easily accessed upscale and literate free market all contributed to America's rapid industrialization. The availability of capital, development by the free market of navigable rivers, and coastal waterways, and the abundance of natural resources facilitated the cheap extraction of energy all contributed to America's rapid industrialization. Fast transport by the very large railroad built in the mid-19th century, and the Interstate Highway System built in the late 20th century, enlarged the markets and reduced shipping and production costs. The legal system facilitated business operations and guaranteed contracts. Cut off from Europe by the embargo and the British blockade in the War of 1812 (1807–15), entrepreneurs opened factories in the Northeast that set the stage for rapid industrialization modeled on British innovations.
From its emergence as an independent nation, the United States has encouraged science and innovation. As a result, the United States has been the birthplace of 161 of Britannica's 321 Greatest Inventions, including items such as the airplane, internet, microchip, laser, cellphone, refrigerator, email, microwave, personal computer, Liquid-crystal display and light-emitting diode technology, air conditioning, assembly line, supermarket, bar code, automated teller machine, and many more.
