In 2011, President Obama proclaimed January 2012 National Slavery and Human Trafficking Prevention Month:
"With the start of each year, we commemorate the anniversaries of the Emancipation Proclamation, which became effective on January 1, 1863, and the 13th Amendment to abolish slavery, which was signed by President Abraham Lincoln and submitted to the States for ratification on February 1, 1865.
These documents stand as testaments to the gains we have made in pursuit of freedom and justice for all, and they remind us of the work that remains to be done. This month, I urge all Americans to educate themselves about all forms of modern slavery and the signs and consequences of human trafficking. Together, and in cooperation with our partners around the world, we can work to end this terrible injustice and protect the rights to life and liberty entrusted to us by our forebears and owed to our children."
