CONSIGNOR, contracts. One who makes a consignment to another. 2. When goods are consigned to be sold on commission, and the property remains in the consignor; or when goods have been consigned upon a credit, and the consignee has become a bankrupt or failed, the consignor has a right to stop them in transitu. (q.v.) Abbot on Sh. p. 3, c. 3.
Only in December 1865, when the 13th Amendment went into effect on a national scale, did slavery cease in Delaware. By then there were only a few hundred left. Many male slaves had enlisted in black regiments during the war.
Slavery started long before the USA. The Portuguese and Spanish began the slave trade from Africa in the 1400's. They leveraged tribal warfare to convince various other tribes to sell them people captured in battle.
