In those times it did not happen that if anyone were unable to go on living in his own home and estate he immediately went away into some foreign country. The rightful owner was an adventurer, certainly, but emigration was not such an easy matter then; he had neither the wherewithal nor the facilities. And so he became a kind of serf, he with his followers—a kind of serf attached to his own estate. His own property had been wrested from him and he, together with a number of those who once used to accompany him on adventures were forced to work as serfs.
