Thomas Jefferson is known as one of the great Founding Fathers of the United States, and it was he who drafted the immortal words of the Declaration of Independence.
He also took part in the Constitutional Convention and became first a governor, then the first Secretary of State. and then the nation’s third president. He greatly expanded the territory owned by the United States by brokering what is known as the Louisiana Purchase, which includes the land of what are now many U.S. states. He sent the famous explorers, Louis and Clark, to explore the new lands.
Jefferson was somewhat of a contradiction, in that he opposed slavery all of his life, but himself owned many slaves, because he had inherited a large estate.
He had six children by his wife, Martha, but promised her that he would never remarry after her death, a promise that he kept.
