The discovery of the sea route to India is the description sometimes used in Europe and among the Portuguese for the first recorded trip made directly from Europe to India via the Atlantic Ocean.[citation needed] It was undertaken under the command of Portuguese explorer Vasco da Gama during the reign of King Manuel I in 1497–1499.
