Concordia market graveyard was a historic country in Italy, located around the town of Concordia sulla Secchia in the current region of Emilia-Romagna. It consisted of the Middle Ages until 1711.
Concordia was one of the many city states in northern Italy. Originally a glory was successively elevated to county (1432) and landgraafschap (1596). Almost from the beginning, Concordia was associated with Mirandola in personal union and was also sold to Rinaldo III d'Este, Duke of Modena in 1711. Also see
