Roman empire fell leaving many small kingdoms to arise. Over time, one kingdom, Wessex, grew stronger than the others and conquered the other kingdoms. Wessex unified forming England into a single nation in the 1800s.
<u>Explanation:</u>
In the early 1700s, England then unifies with Scotland, Wales, and Northern Ireland to form Great Britain.
In 1707 ,the United Kingdom of Great Britain came into being as the results of Acts of Union being passed by parliaments of England and Scotland to ratify the 1706 Treaty of Union and to unite the two kingdoms.
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.
