The SS Imperator was a German ocean liner that was the world's largest passenger ship upon its completion in 1913. It was operated by the Hamburg America Line and was part of a trio of ships known as the "Imperator" class. The ship had a luxurious interior, with amenities such as a swimming pool, Turkish baths, and elegant dining rooms. During World War I, the Imperator was used as a troop transport and was later seized by the United States in 1917. After the war, the ship was transferred to the Cunard Line and renamed the RMS Berengaria. It then underwent a significant renovation to cater to the transatlantic passenger trade. The Berengaria had a successful career as a passenger liner until it was retired in 1938. The ship was eventually scrapped in 1946. The SS Imperator played a significant role in the history of ocean liners, as one of the largest and most luxurious ships of its time, and its transformation into the RMS Berengaria marked a new chapter in its maritime legacy.
