Abraham Lincoln was the first president elected from the Republican Party.
Explanation:
In 1860 Lincoln secured his candidacy for the presidency of the United States by the Republican Party, a new political party created in 1854. Although he barely had support from the southern states, defenders of slavery, he swept north and was named president in 1860, being the first Republican president of the United States. Before even reaching the White House, his victory and lack of agreement on the essential issue of slavery caused that seven southern states split off to create the Confederate States of America, and the following outbreak of the Civil War.
