When did Giovanni explore?

Giovanni Caboto, known as John Cabot, explored in the late 15th century, with his most notable voyage taking place in 1497. He sailed under the English flag, seeking a westward route to Asia. Cabot is credited with being one of the first Europeans to explore the North American mainland, landing likely in present-day Newfoundland. His explorations were significant in laying the groundwork for later English claims in North America.
