The Bayern class was a class of four super-dreadnought battleships built by the German Kaiserliche Marine. The class comprised Bayern, Baden, Sachsen, and Württemberg. Construction started on the ships shortly before World War I; Baden was laid down in 1913, Bayern and Sachsen followed in 1914, and Württemberg, the final ship, was laid down in 1915. Only Baden and Bayern were completed, due to shipbuilding priorities changing as the war dragged on. It was determined that U-boats were more valuable to the war effort, and so work on new battleships was slowed and ultimately stopped altogether. As a result, Bayern and Baden were the last German battleships completed by the Kaiserliche Marine.

The Queen Elizabeth-class battleships were a group of five super-dreadnoughts built for the Royal Navy during the 1910s. These battleships were superior in firepower, protection and speed to their Royal Navy predecessors of the Iron Duke class as well as preceding German classes such as the König class. The corresponding Bayern-class ships were generally considered competitive, although the Queen Elizabeth class were 2 knots (3.7 km/h) faster and outnumbered the German class 5:2. The Queen Elizabeths are generally considered the first fast battleships of their day.
