Hence the real unity was established only in the 10th century, largely thanks to the proud descendants of the great Koguryŏ.

The rationale behind this interpretation is easy to understand, since the borders of Silla are roughly similar to those of present-day South Korea, while Koguryŏ controlled what is now the realm of the Kim dynasty.
