Catherine of Brandenburg (28 May 1602 – 27 August 1649) was an electedPrincess of Transylvania between 1629 and 1630. She was the daughter ofJohn Sigismund, Elector of Brandenburg, andAnna of Prussia.
Catherine was the youngest daughter of Johann Sigismund and Anna. Catherine's maternal grandparents wereMarie Eleonore of Cleves andAlbert Frederick of Prussia, while her paternal grandparents wereJoachim Frederick, Margrave of Brandenburg and his first wifeCatherine of Brandenburg-Küstrin.
The relationship between her parents was said to be volatile with her father prone to drunken rages where her mother is reported to have thrown plates and glasses at her spouse during arguments. Although Anna was described as intellectually superior to her spouse, she was also considered temperamental and strong-willed.
In 1613, Johann Sigismund converted toCalvinism while his wife and daughters remained staunchlyLutheran.[1]
In 1619, when Catherine was 16 years old, her father died and was succeeded by her brother George William. The following year, Catherine's oldest sister Maria Eleonora was considered a marriage candidate of the young Gustavus Adolphus of Sweden. But because of their brother's refusal to allow their sister's marriage, their mother Anna (who was in favour of it) sent both sisters to the Braunschweig court where their older sister Anna Sophia (married toFrederick Ulrich, Duke of Brunswick-Lüneburg) lived. This was so Georg Wilhelm could not keep Maria Eleonora from leaving Brandenburg.
Then through the help of the Swedish Chancellor of the ExchequerAxel Oxenstierna both sisters accompanied by Oxenstierna and his mother Barbro Bielke left for Sweden. Catherine and her mother then lived in Sweden for several years after the marriage of her sister Maria Eleonora to king Gustavus Adolphus ofSweden in 1620.
Catherine was educated to become an ideal consort of a ruler and was "richly decorated with virtues suitable to a princely woman".[2] As for her appearance, although she was very short, she had a shapely figure and pleasing face.
Catherine had many important family connections that made her a very eligible bridal candidate. Notwithstanding her sister being queen of Sweden, she was also a cousin ofFrederick III of Denmark.
In 1625, her mother Anna died.
On 2 March 1626, she marriedGabriel Bethlen, prince of Transylvania.[3] The marriage allied the Protestant Prince of Transylvania with the Protestant powers of Denmark, Sweden and the Palatinate. Aproxy marriage was celebrated in Cölln an der Spree, after which the bride set off accompanied by her sister Anna Sophia, for her new homeland, where a second marriage in person performed inKosice in Transylvania (now in Slovakia) took place. The couple settled inAlba Iulia in Transylvania.
The marriage is not described as happy. Gabriel Bethlen had numerous mistresses, and Catherine had lovers as well, most notably Istvan Csaky – because of the double standards of the time, however, only Catherine was given a bad reputation because of this.[4]
The marriage remained childless. It was a condition in the marriage contract that Catherine should be elected the successor of her spouse, and she was elected as his successor by Transylvania's Diet and swore her solemn oath as his successor on May-June 1626, after which her status was confirmed by theOttoman Porte through the effort of the Dutch and English allies of Bethlen.[5] Bethlen confirmed her election in his political will, in which he noted "perhaps no other illustrious princely woman has ever been elected."[6]
Prince Gabriel Bethlen died on 25 November 1629.
Her policy was to bring Transylvania back under the influence ofHoly Roman Emperor Ferdinand II. She tried in vain for a year to hold on to the throne, supporting herself on her favorite Istvan Csaky, but she was forced to abandon power on 21 September 1630.

TheSublime Porte, first chose her brother-in-lawStephen Bethlen as successor, but finallyGeorge I Rákóczi succeeded her. The new prince was elected on 1 December 1630.
Catherine of Hohenzollern moved back to Germany where she converted to Catholicism in 1633 and marriedFrancis Charles of Saxe-Lauenburg in 1639. She died on 27 August 1649 at the home of her sister Anna Sophia inSchöningen.
