Alfred Thayer Mahan was an American naval officer who is known for his influence on sea power during 19 and early 20 centuries.
According to Mahan, sea power is highly influenced by the distribution of the populations, and their characteristics that maintain stable and efficient working ability. so, such efficiency and stability come from racial traits and native American citizens are good at it.
This thought of Mahan invokes racial differences to support his arguments.
As a war leader, Lincoln employed the style that had served him as a politician—a description of himself, incidentally, that he was not ashamed to accept. He preferred to react to problems and to the circumstances that others had created rather than to originate policies and lay out long-range designs.
With the election of Abraham Lincoln (the first Republican president) in 1860, the Party's success in guiding the Union to victory in the American Civil War, and the Party's role in the abolition of slavery, the Republican Party largely dominated the national political scene until 1932.
