NEW YORK - Secretary of State Hillary Rodham Clinton and New York City Mayor Michael Bloomberg welcomed Dutch royalty to New York for the 400th anniversary of Henry Hudson's voyage up the river that now bears his name.

Tuesday's festivities included military vessels, Dutch barges and a replica of Hudson's Half Moon.

Willem-Alexander, Crown Prince of Orange, and his wife, Princess Maxima, visited the Intrepid, a World War II aircraft carrier that's now a museum. The prince said New York was built on the values of Dutch-American pioneers, including a passion for liberty.

The royals also were visiting the U.S. Military Academy at West Point, N.Y., and meeting with the governor.

Hudson, an Englishman, was working for the Dutch during his September 1609 sail.
