The name Titanic was derived from Greek mythology and meant gigantic. Built in Belfast, Ireland, in the United Kingdom of Great Britain and Ireland (as it then was), the RMS Titanic was the second of the three Olympic-class ocean liners—the first was the RMS Olympic and the third was the HMHS Britannic.[5] They were by far the largest vessels of the British shipping company White Star Line's fleet, which comprised 29 steamers and tenders in 1912.[6] The three ships had their genesis in a discussion in mid-1907 between the White Star Line's chairman, J. Bruce Ismay, and the American financier J. P. Morgan, who controlled the White Star Line's parent corporation, the International Mercantile Marine Co. (IMM).
