Reventlow is the name of a Holstein and Mecklenburg Dano-German noble family, which belongs to the Equites Originarii Schleswig-Holstein. Alternate spellings include Revetlo, Reventlo, Reventlau, Reventlou, Reventlow, Refendtlof and Reffentloff. History In 1223, Godescalcus de Revetlo of Holstein was first mentioned in writing. He was vassal of Count Albrecht of Orlamünde and Holstein. In 1236 and 1258, Thitlevus de Revetlow was in Mecklenburg in the wake of the Prince Johann I. In both countries, members of the family were able to gain significant professional and economic positions over time. The old Holstein line, also found from the 14th to the 16th century in Funen, ended in 1752. With the extinction of the Gallentiner branch in 1772, the Mecklenburg branch also ended. Relatives from this branch, however, had previously settled in the Duchy of Schleswig. From Ziesendorf (in Mecklenburg) came Detlef Reventlow, who was appointed chancellor of Christian IV of Denmark in 1632. He was progenitor of two new branches, both of which came to great influence. The older branch acquired the Danish lord-dignity in 1767. The younger branch had acquired by 1673 the Danish Graf and on July 23, 1706, to Vienna the Count of the Holy Roman Empire. Conrad von Reventlow (1644–1708), Grand Chancellor and Prime Minister of Christian V of Denmark, received the higher feudal rank and was awarded the Liege County of Reventlou - Sandbjerg in Schleswig. His son acquired the feudal county Christianssæde on Lolland and the feudal barony Brahetrolleborg on Funen. The younger daughter of Conrad von Reventlow, Anna Sophie von Reventlow (1693–1743), became in 1712 consort of King Frederick IV of Denmark and Duchess of Schleswig. In 1721 she was crowned Queen of Denmark. Other Reventlows were related by marriage to the Dukes of Holstein. The Reventlow family counts important personalities of the European aristocracy, including the last German empress Auguste Victoria. Detlev von Reventlow (1712–1783), heir of the Altenhof and Glasau estates, bought Gut Emkendorf in 1764, from Detlef von Reventlow Gut Wittenberg in 1767, and the Altenhof neighboring Gut Aschau in 1782. The Counts of Reventlow-Criminil with a Danish diploma of 1815 belonged in the male line to the French Marquis Le Merchier de Criminil. Joseph and Heinrich were the sons of a niece of Julia von Reventlow who she and her husband Friedrich Karl Reventlow adopted. Joseph inherited the Emkendorf in 1828; his descendants sold it in 1929.
