# The first voyage returns to Lisbon as a completed round voyage

Date: 1499

## The fact

Public English prints return to Portugal with a surviving portion of the fleet. A completed round voyage is an industrial-route demonstration. Twin of scurvy deaths.

It is one event.

## Context

Shared crews and ships. High confidence on the received return.

[Vasco da Gama](/people/vasco-da-gama) Shared work with other named actors remains in the record.

Vasco da Gama’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

Conventional years are c. 1460s–1524.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Britannica — Vasco da Gama and A Journal of the First Voyage of Vasco da Gama — public English independently describe this instrument.

Official or archival record: Britannica — Vasco da Gama (https://www.britannica.com/biography/Vasco-da-Gama; Encyclopaedia Britannica).

## Significance

Printed 1499 return is not a modern AIS track.

## What is established and what is not

Established as a dated public record of this instrument.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Vasco da Gama.

They are not a public rating.

The driver `industrial-policy-activism` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Vasco da Gama did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. Driver `industrial-policy-activism` is attached because the Significance sentence names a mechanism from The first voyage returns to Lisbon as a completed round voyage at 1499-09-09, not because a standing driver list needed coverage.
