Commonwealth at 70

Between April 2019 and April 2020 we are celebrating 70 years of the Commonwealth. The modern Commonwealth was born on 26 April 1949 with the signing of the London Declaration.

More about our history

In the 70 years since, the relevance and value of the Commonwealth has grown as the number of member countries has grown from 8 countries in 1949 to 54 in 2020.

Celebrations at the Commonwealth Secretariat

To celebrate the anniversary, the Secretary-General hosted a garden party at the Commonwealth’s headquarters, Marlborough House.

She said: “In celebrating 70 years of the Commonwealth we recall with pride and satisfaction the impressive record of impact and achievement which have brought sustainable development to the people of our diverse family of nations, with ever more inclusive progress and prosperity.

“Programmes such as the Commonwealth Connectivity Agenda on Trade and Investment, and the Commonwealth Blue Charter on ocean governance, are examples of recent agreement by our member nations to collaborate in new ways in response to the current needs of our countries and communities.

“As rising generations respond afresh and build together in the renowned Commonwealth spirit of goodwill, we can be assured that through the next 70 years and beyond this great family will rise to even greater levels of mutual support, conscious as always that independence and interdependence go hand in hand for the people and nations of a connected Commonwealth.”


Across the Commonwealth, organisations are celebrating the 70th Anniversary with a series of events, conferences, competitions and workshops throughout the year.
