The earliest evidence of lending money in the truest sense was documented in the early Agrarian societies somewhere around 4,000 B.C. Of course, paper and coin currency wasn't in use back then, however people in these societies would lend animals or crops to others in an effort to increase production of these items, which represented wealth during this time.
Paper money in the United States has a long and storied history. The U.S. Issued its first paper currency note in 1690 when the Massachusetts colonies began printing and using money to purchase goods. In 1775, the colonies issued paper money to the Continental Congress as a way to provide financing for the Revolutionary War.
