Events and ideas: 1700-1800

From the 18th century to the early 19th century, European and American scientists studied "ethnological science". Human concept is divided into different races and inequal races. They tried to explain the contradiction between the human beliefs expressed during the American and French revolution and the emergence of slavery in several countries of the United States and Europe (reading, who is the human being Please see?). The work of an important scientist like Samuel Morton gives racist correct justification. Journalists, teachers and missionaries have begun to spread their findings. Reginald Horsman, a historian who has studied major publications at the time, pointed out as follows. "People know that Caucasians have been born outstandingly, are responsible for the world civilization, they are overwhelmed, even disappearing." 2

Due to contradictory ideas between the northern states and the southern states, many events in the mid 1870s and mid 1800s caused a civil war. The conflict that caused the inter-Korean civil war involved economic, social and political events. At the same time, slavery was created to support intense debate between slavery and anti-slavery. There was intense debate between the northern and southern states for the agricultural economy of the southern provinces. Geographical location

The economy of Louisiana is mainly based on agriculture, cotton in the northern part of the state and sugarcane in the south was the main crop from the 1800s to the 19th century. Logging began to grow in the second half of the 19th century and occupies an important part of the state economy of the 21st century. World War II accelerated the growth of the Louisiana industry, which led to a marked increase in the number of workers engaged in manufacturing. Oil and gas mining is also growing rapidly. Production of chemical substances is based on the existing hydrocarbon, sulfur, salt and water resources of the state that thrived from 1947 to 1957 and took the first step toward oil production for the first time. In the late 20th century, the expansion of service industries, especially tourism, retail and government agencies, helped to position the service industry as the state's largest employer.
