Free slaves as union forces won back territory, abolish slavery, and the war was being fought against slavery, so Europe gave no support to the South.
The South Carolina Colony was one of the 13 original colonies in America, which were divided into three regions including the New England Colonies, the Middle Colonies, and the Southern Colonies. The South Carolina Colony was originally one colony along with the North Carolina, which was founded in 1633 under the Charter of Carolina. In 1712 the original colony was divided into North and South Carolina. In 1729 the South Carolina Colony became a royal colony.
South Carolina territory was very privileged, with natural resources as forests, fish, and land suitable for farming and large plantations. In this land, they grew a variety of crops including cotton, tobacco, vegetables, fruit, and livestock. The plantations in the South Carolina Colony were often massive, and the warm climate of the Southern Colonies made it suitable for farming and agricultural pursuits most of the year.
But the main reason was the open use of slave labour, that along with the resources above, made this colony so profitable to the eight Lord Proprietors and to King Charles II.
The correct answer is 3. During the Hoover administration, the Smoot Hawley tariff greatly raised rates on imported products.
The Hawley-Smoot Act was a law passed in the United States on June 17, 1930, proposed by Senators Reed Smoot and Willis C. Hawley, which unilaterally raised US tariffs on imported products, to try to mitigate the effects of the Great Depression that began in 1929. The remarkable feature of this regulation was the notable increase in the tariffs set and its extension to nearly 20,000 imported products, which caused a strong impact on international trade at the time.
