High Quality Content by WIKIPEDIA articles! Tsesarevich (Цесаревич) was a pre-dreadnought battleship of the Imperial Russian Navy, built in France at the end of the 19th century. The ship was named after the Tsesarevich — the title reserved for the eldest son of the Tsar and heir to the Russian throne. She was based in the Pacific and fought in the Russo-Japanese War, and was the flagship of Admiral Wilgelm Vitgeft in the Battle of the Yellow Sea. The Tsesarevich design formed the basis of the Borodino-class battleships which were built in Russia.
