Beginning of the modern Commonwealth
1949
Eight countries - Australia, Canada, India, New Zealand, Pakistan, South Africa, Sri Lanka and the United Kingdom - come together to reform their old association into the modern Commonwealth.
Leaders set down the terms of their voluntary association as “free and equal members of the Commonwealth of Nations, freely co-operating in the pursuit of peace, liberty and progress.”
“In this world which is today sick and which has not recovered from so many wounds... it is necessary that we touch upon the world's problems, not with passion and prejudice... but in a friendly way and with a touch of healing."
Shri Jawaharlal Nehru, Prime Minister of India, in a speech to the Constituent Assembly, New Delhi, 1949

1965
Based in Marlborough House in London, UK, the Commonwealth Secretariat was established in 1965 to support member countries to achieve the Commonwealth’s aims of development, democracy and peace and act as “a visible symbol of the spirit of co-operation that animates the Commonwealth”.
Arnold Smith, seen here outside Marlborough House with Law Ministers, was appointed its first Secretary-General and served from 1965 to 1975.
When statesmen who have led their nations to independence have decided to seek membership in the Commonwealth, they have not appeared to be motivated by sentimentality about the past, but by a constructive vision of the future and by realistic assessments about their country’s national interest.
Arnold Smith, Commonwealth Secretary-General (1965-1975)

Adoption of the Langkawi Declaration on the Environment
1989
Commonwealth leaders expressed deep concerns at threats posed to the environment in the landmark Langkawi Declaration on the Environment.

The global environmental issue is a matter that concerns every nation, every society, every individual. The Langkawi Declaration was an important contribution in the efforts to effectively address environmental problems in a global perspective.
