When the colonists first settled in what is now Delaware most of them came as English indentured servants, of course later on there were African slaves. In the early 1800's the majority of the African population in Delaware were free, though there was not any official legislature declaring them free. Delaware remained in the Union during the Civil War. In 1861 Abraham Lincoln pushed for the remaining slave holders to be compensated in return of the freedom of the slaves, at the time there were less than 1,800 slaves in Delaware (mostly in Sussex county) and in 1862 slavery was declared unlawful in all U.S. territories
