Wettin was laid down in October 1899, and was completed October 1902. She and her sister ships—Wittelsbach, Zähringen, Schwaben and Mecklenburg—were the first capital ships built under the Navy Law of 1898. Wettin was armed with a main battery of four 24 cm (9.4 in) guns and had a top speed of 18 knots (33 km/h; 21 mph).
