WASHINGTON (AP) - Officials are announcing a series of events to celebrate the 150th anniversary of District of Columbia Compensated Emancipation Act.
The anniversary of the 1862 federal law that freed more than 3,000 slaves in Washington is next month.
On April 16, the city plans to hold an Emancipation Parade along Pennsylvania Avenue in northwest, as well as a street festival at Freedom Plaza.
A march also will be held among the memorials on the National Mall on April 11.
Lectures, concerts and ceremonies related to slavery, emancipation and civil rights are also planned at venues across the city.
The compensated emancipation act was signed into law by President Lincoln, nine months before he issued the more famous Emancipation Proclamation.
