When did lincoln give his "a house divided" speech?

a. while running for the u. s. senate

b. at his first presidential inauguration

c. while running for his first presidential term

d. during his term in the illinois state legislature

The correct answer is A. Lincoln gave his "A House Divided" speech while running for the U.S. Senate.

Explanation:

The House Divided speech was delivered by Abraham Lincoln on June 16, 1858, in Springfield, by accepting the nomination of the Illinois Republican Party to run for the Senate. The speech became the basis of his campaign against Stephen A. Douglas, with whom he debated before the election, and by whom he was ultimately defeated in the Senate race.

Lincoln's lecture became a lasting picture of the danger of disunity caused by slavery, and served as a communion for the republicans of the northern states.
