New York State celebrated the 225th Anniversary of the American Revolution from 2000 through 2009. The Hudson River Valley Institute focused on a significant historical event relating to the Revolutionary War in the Hudson Valley 225 years ago for each year through 2008 as a part of our Patriots’ Weekends. Re-enactments, public-oriented historical lectures by nationally known historians, and ceremonies honoring those who fought for America's independence were the Weekend's key features.

The weekend will kick-off with a lecture here at Marist College before moving to General George Washington's encampment at Fredricksburgh in 1778, between present-day Pawling and Patterson, New York.

Patriots' Weekend 2005 
In September of 1780, Major John Andre was captured in Tarrytown with proof of General Benedict Arnold’s betrayal. Andre was hanged at Tappan in October of the same year, less than a week after Arnold successfully defected to the British lines. We will begin with the Charlotte Cunneen-Hackett Lecture in Hudson River Valley History at Marist on Thursday, September 29th. There are lectures planned at the USMA West Point and the Tarrytown Music Hall for Friday, September 30th, and commemorative celebrations of these events will take place in both Westchester and Rockland Counties Saturday and Sunday, October 1st and 2nd.

Patriots' Weekend 2006 
The weekend will begin with the Charlotte Cunneen-Hackett Lecture in Hudson River Valley History at Marist College to be followed by events in Westchester and Rockland Counties to commemorate the march of the French Army under General Rochambeau to Philipsburgh, New York to join General Washington's Continental Army for the siege of New York City in July-August 1781. Both armies then marched south to win the Battle of Yorktown, Virginia.

Patriots' Weekend 2007 
Patriots' Weekend 2007 encompassed three weekends of events. The first commemoration occurred in April with General and Mrs. Washington arriving in Newburgh. Reenactors who marched the Washington-Rochambeau Revolutionary Route from Rhode Island to Virginia crossed the Hudson at Stony and Verplank Points on their way back in September, and the Continental Army established what would be its final encampment in New Windsor at the end of October.

Patriots' Weekend 2008 
There were three weekends of events in 2008, beginning with “Cease Fire – The War Ends, 1783” at the New Windsor Cantonment State Historic Site in New Windsor, NY, followed by events on the river and in Tappan and Constitution Island in Cold Spring.
