Henry Hudson begins his exploration of the Hudson River while aboard the Halve Maen.

Halve Maen (Dutch pronunciation: [lv man]; English: Half Moon) was a Dutch East India Company vlieboot (similar to a carrack) that sailed into what is now New York Harbor in September 1609. She was commissioned by the VOC Chamber of Amsterdam in the Dutch Republic to covertly find a western passage to China. The ship was captained by Henry Hudson, an Englishman in the service of the Dutch Republic.In 1909, the Kingdom of the Netherlands presented the United States with a replica of Halve Maen to commemorate the 300th anniversary of Hudson's voyage; the replica was destroyed in a fire in 1934. Fifty years later, the New Netherland Museum commissioned a second replica.

Henry Hudson (c. 1565 – disappeared 23 June 1611) was an English sea explorer and navigator during the early 17th century, best known for his explorations of present-day Canada and parts of the northeastern United States.

In 1607 and 1608, Hudson made two attempts on behalf of English merchants to find a rumoured Northeast Passage to Cathay via a route above the Arctic Circle. In 1609, he landed in North America on behalf of the Dutch East India Company and explored the region around the modern New York metropolitan area. Looking for a Northwest Passage to Asia on his ship Halve Maen ("Half Moon"), he sailed up the Hudson River, which was later named after him, and thereby laid the foundation for Dutch colonization of the region.

On his final expedition, while still searching for the Northwest Passage, Hudson became the first European to see Hudson Strait and the immense Hudson Bay. In 1611, after wintering on the shore of James Bay, Hudson wanted to press on to the west, but most of his crew mutinied. The mutineers cast Hudson, his son, and seven others adrift; the Hudsons and their companions were never seen again.
