Abigail Adams was the wife of America's second president, John Adams, and one of the most influential women of the founding era. She exchanged more than 1,100 letters with her husband alone — part of a lifetime correspondence running into the thousands — full of sharp political opinions, most famously her 1776 letter urging him to "remember the ladies" as the new nation's laws were being written. Her letters give historians a rare, detailed window into life and politics during the American Revolution.
