On 6th of November 2009, President of the USA Barack Obama signed a congressional resolution conferring honorary U.S. citizenship to Revolutionary War hero Casimir Pulaski.

Casimir Pulaski was a Polish nobleman who is known as the ‘father of the American Cavalry.

Born March 6th 1745 in Warsaw, Poland. This was a time when Imperial Russia was exerting its influence across neighbouring countries, including Poland. Casimir Pulaski fought for the independence of Poland.

In 1772, combined Austrian/Prussian forces invaded Poland and Pulaski had to flee. He ended up in France where he met Benjamin Franklin. From there he travelled to America in 1777. Pulaski was now engaged fighting for the independence of America.

In Washington’s army he served at Brandywine, was made general and chief of cavalry by Congress, and fought at Germantown and in the winter campaign of 1777–78. The Pułaski Legion, a mixed corps of cavalry and infantry that he formed in 1778, exploited his experience in guerrilla warfare. In May 1779 he defended Charleston. Wounded at Savannah on October 9, 1779, he died aboard the Wasp.

In 2010, after a re-examination of his remains experts concluded that Casimir Pulaski was intersex – that is whilst he identified as a man, he did not conform to the binary definitions of male and female.
