Title:
Kenya

Context:
A constitutional change was considered that would eliminate the position of Prime Minister and simultaneously reduce the powers of the President. A referendum to vote on the proposed constitution was held on 4 August 2010, and the new constitution passed by a wide margin. Among other things, the new constitution delegates more power to local governments and gives Kenyans a bill of rights. It was promulgated on 27 August 2010 at a euphoric ceremony in Nairobi's Uhuru Park, accompanied by a 21-gun salute. The event was attended by various African leaders and praised by the international community. As of that day, the new constitution heralding the Second Republic came into force.

Question:
When was the new constitution promulgated?

27 August 2010
