The kingdom of Goryeo became first known to Westerners when Afonso de Albuquerque conquered Malacca in 1511 and described the peoples who traded with this part of the world known by the Portuguese as the Gores. Despite the coexistence of the spellings Corea and Korea in 19th century publications, some Koreans believe that Imperial Japan, around the time of the Japanese occupation, intentionally standardized the spelling on Korea, making Japan appear first alphabetically.
