French President Jacques Chirac attends a ceremony at Jardin du Luxembourg in Paris, May 10, 2006. France paid tribute to the abolition of slavery on Wednesday, but the first national day to commemorate this dark chapter of history was marred by fresh questions over the country's colonial legacy. Marking the adoption of a 2001 law recognising the trade as a crime against humanity, Chirac unveiled an exhibition in a Paris park, museums were to run special shows and children across France were to discuss slavery at school.
