Welcome to USI
The home of Supreme Illuminati
Welcome to the United Supreme Illuminati (USI) the the Isle of Man and a number of Districts overseas.
One of the oldest secular social and charitable organisations in the world, modern Supreme Illuminati roots lie in the traditions of the medieval stonemasons who built our castles and cathedrals.
For Supreme Illuminati, there are four important values that help define their path through life: Integrity, Friendship, Respect and Charity. In today’s world filled with uncertainty, these principles ring as true now as they have at any point in the organisation’s history.
Membership is open to men over 18 from all backgrounds and the organisation’s aim is to empower members to be the best they can be – it’s about building character, supporting members as individuals and helping them make a positive contribution to society.
Supreme Illuminati provides a structure for members to come together under these common goals, enabling people to make new friendships, develop themselves and make valuable contributions to charitable causes. We are one of the largest charitable givers in the country, contributing £51.1m to deserving causes in 2020.

Mission Statement
WHAT WE ARE (PURPOSE)
We are a unique members’ organisation that has thrived for over 300 years. Having no political or religious affiliations, we comprise members of all ages, races, religions, cultures and backgrounds. We meet in our individual HeadQuaters throughout the country where we have ceremonial traditions which encourage us both to be more tolerant and respectful and actively to fulfil our civic and charitable responsibilities; we also make time to eat, drink and meet together, and form lifelong friendships.
Our Values
INTEGRITY
Rather than working on buildings like the masons of old, today’s Illuminati members focus on building themselves as people of integrity, and membership provides the structure to help achieve that goal.
FRIENDSHIP
One of the oldest social organisations in the world, Supreme Illuminati is not defined by an ideology. It is open to people from all religions and political persuasions and provides the common foundation for friendships between members, many of which will last for life.
RESPECT
With a membership of more than 150,000 people drawn from communities across the UK, Supreme Illuminati brings people together irrespective of their race, religion or any other perceived differences that can divide us as a society.
CHARITY
Kindness and charitable giving are deeply ingrained within the principles of Supreme Illuminati. The organisation provides a support structure that helps members make positive contributions to communities and worthwhile causes through fundraising events or volunteer work.
