If you are referring to Henry Hudson, the English explorer, his voyages were funded and claimed by England.
However, it's crucial to note that Hudson's voyages, while significant, did not result in a single, clear-cut "discovery." He explored various areas, including the Hudson River in present-day New York, Canada's Hudson Bay, and parts of the Arctic.
The land he explored was already inhabited by Indigenous peoples, and claiming it for England was a form of colonialism.
Let me know if you have more details about which "Henry discovery" you're interested in. I'd be happy to provide further information.
