Read the following paragraph and extract the answer for the question: In what year was there a runoff election between Salem and Eugene to decide which would be capital in the state that selected Oregon city as its first capital?

Before the creation of the Oregon Territory in 1848, the Oregon Country provisional government, through legislation on June 27, 1844, and December 19, 1845, selected Oregon City as Oregon's first capital.

They decided to ask the people of the territory to vote on the question. A vote was to be held in June 1856, after which the two cities receiving the most votes would have a runoff.
