Casimir Pulaski, or Kazimierz Pulaski in Polish (March 6, 1745 – October 11, 1779), was a Polish soldier, nobleman, and politician who has been called "the father of American cavalry".
A member of the Polish landed nobility, Pulaski was a military commander for the Bar Confederation and fought against Russian domination of the Polish–Lithuanian Commonwealth. When this uprising failed, he emigrated to North America as a soldier of fortune. During the American Revolutionary War, he saved the life of George Washington and became a general in the Continental Army. He died of wounds suffered in the Battle of Savannah. Pulaski is one of only seven people to be awarded honorary United States citizenship.
