Although the Transatlantic slave trade was made illegal in the 19th century, it was acknowledged that many forms of slavery persisted, so new laws against 20th century slavery were needed.

Below is a timeline of the main pieces of international and regional legislation against slavery that have been adopted in the last 100 years. The actual wording of many of the conventions listed below can be found at Human Rights Education Associates. |
