It was written in the early 12th century. It is sometimes ascribed to the Kievan monk Nestor. So at previous times, it was known as Nestor's Chronicles.

What I'll share is a version of the Russian Primary Chronicle known as the Laurentian Text from 1377. And this is, of course, an English translation.
