A Dutch proposal to build new battleships was originally tendered in 1912, after years of concern over the expansion of the Imperial Japanese Navy and the withdrawal of allied British warships from the China Station. Only four coastal defense ships were planned, but naval experts and the Tweede Kamer (lower house of the parliament) believed that acquiring dreadnoughts would provide a stronger defense for the Nederlands-Indië (Netherlands East Indies, abbr. NEI), so a Royal Commission was formed in June 1912.
