Rajčin Sudić (c. 1335 – after 1360) was a Serbian monk-scribe who lived and worked during the time of Lord Vojihna, the father of Jefimija.
From the inscription Rajčin Sudić left in the margin of the Chronicles written in the 14th century, we know that he was a prisoner of some feudal ruler of that period.
That is usurpation of administrative posts by men of two, three and more fiefs, an abuse which threatened to follow the overthrow of Vojihna—he must have been accused by someone that Sudić allegedly conspired to assist Vojihna's enemies and was imprisoned for five months, along with another "accomplice" by the name of Kijevac.
May that God leads us from the lowest pit, for the Holy Scriptures say, "Put not your trust in princes, in a son of man, in whom there is no help.
O sorrow, my little sorrow, there is no one to whom I can talk to about you—only to you, Mother of God of Kosenica (monastery); lead me out of peril, for Christ knows that they falsely accused us (innocent ones); he (the Governor) did not let us have justice, a trial, or sentence, but he imprisoned us, the innocent, myself and Kijevac, and chained us into a tower; may God see it and no one else.The probable date of the inscription is the year 1360.
