Christopher regained the territories that were lost by his father to the Palatinate and its allies. He maneuvered to keep these territories united under his son and successor Philip I, but his efforts were thwarted by Louis XII of France. In 1479, the seat of the Margraviate of Baden was moved from Hohenbaden Castle to New Castle (Neues Schloss) of Baden-Baden which was built by him.
In 1489 Christopher became a member of the Swabian League. This was part of his efforts for peaceful coexistence with his neighbors (in particular with Württemberg and the cities of Weil and Strasbourg). Within the protection of this South West German pact, Christopher advanced the internal development of his dominion.
Christopher's winegrowing law of 1495 was a major step in improving the quality of wine produced in Baden.[2] His wife Ottilie was from a famous wine-making family in the Kraichgau, the Counts of Katzenelnbogen.
By 1503, Christopher was responsible for uniting all the Badener lands when the Baden-Sausenberg died without male heirs. In 1515, before his death, he divided the Margraviate among his sons Philipp, Bernhard, and Ernst. However, Philipp who had succeeded him died childless, and his share was passed down to his brothers Bernhard and Ernst. Thus, Bernhard founded the so-called "Bernardine line" of Baden-Baden and Ernst founded the "Ernestine line" of Baden-Durlach.
^"... The House of Baden, which has held the title of margrave since 1112, is closely associated with the development of quality winegrowing in Baden. In 1495, the margraves enacted the first wine laws. In the 18th century, they adopted single-variety Riesling cultivation and introduced Chasselas grapes in the southern Baden district of Markgräflerland. Similarly, in 1923 the Müller-Thurgau grape variety was first cultivated at Lake Constance on the family’s estates. Schloss Salem on Lake Constance is the ancestral home of the House of Baden and the headquarters of its vineyard estate. The estate is owned personally by the margraves of Baden and its planted area of 135 hectares makes it one of the largest private winegrowing estates in Germany. It is also a member of the Association of German Prädikat Wine Estates (VDP)...."
