Names similar to Bhutan—including Bohtan, Buhtan, Bottanthis, Bottan and Bottanter—began to appear in Europe around the 1580s. Jean-Baptiste Tavernier's 1676 "Six Voyages" is the first to record the name "Boutan". However, these names seem to have referred not to modern Bhutan but to the Kingdom of Tibet. The modern distinction between the two did not begin until well into the Scottish explorer George Bogle's 1774 expedition. Realizing the differences between the two regions, cultures, and states, his final report to the East India Company formally proposed calling the Druk Desi's kingdom "Boutan" and the Panchen Lama's kingdom "Tibet". The EIC's surveyor general James Rennell first anglicized the French name as "Bootan," and then popularized the distinction between it and Greater Tibet.
