John Cabot, born Giovanni Caboto, received English royal authorization from Henry VII to explore westward across the Atlantic under the English flag.
The 1496 letters patent authorized Cabot and his sons to sail to lands unknown to Christian Europeans and to claim territories for the English crown.
Cabot sailed from Bristol in 1497 aboard Matthew with a small crew. The voyage reached land somewhere in the North Atlantic region, most likely in or near present-day Atlantic Canada.
The precise landfall remains disputed. Newfoundland, Labrador, and Cape Breton have all figured in historical arguments because surviving documents are brief and do not provide modern coordinates.
Cabot returned to England and was rewarded, indicating that the voyage was treated as a successful discovery from the English crown’s perspective.
A second expedition in 1498 is far less certain. Several ships sailed, but Cabot’s own fate is unclear in the surviving evidence.
Later English imperial claims sometimes invoked Cabot’s voyage retrospectively. That political use should not be confused with the limited practical occupation achieved in 1497.
For TransitSatellite, the route should show Bristol departure and a broad North Atlantic landfall zone rather than a falsely exact pin where the historical evidence cannot decide among competing locations.
