is used to express speculation. It means 'probably is ~' or 'probably is the case that ~'.
This form has a somewhat old-fashioned feel. In modern Japanese it would be more common to use past + だろう.

A に is often added after the ろう as an implied joining form. At the end of a sentence, that may indicate that the speaker would prefer the outcome described. For example:
ぼく
きみ
ならそんなばかげたこと
わなかったろう

If I were you, I would not have said such nonsense.
