Give 100
The Semidon
A cause-seeding gathering of exactly 100 named participants, convened during the Give 100 observance year to awaken, organise, and multiply support for the Sovereign Shield — the Commonwealth tribute to Queen Elizabeth II at 100 and the founding civic movement for the Institute of Preemptology.
The Gathering
What the Semidon Is
The Semidon is the repeatable civic unit of Give 100. It is not simply an event, and not merely a fundraiser. It gathers 100 named participants to seed practical support for the Institute of Preemptology, incorporating its Queen Elizabeth II Centre for Cervical Cancer Elimination — through gifts, pledges, advocacy, institutional alignment, partnerships, volunteer mobilisation, and public witness.
A Semidon may be convened during the observance by any person or body willing to gather 100 named participants in accordance with the formal criteria of Give 100. Each may be named for its City, convener, host, office, institution, or occasion. The Opening Semidon, convened on the International Day of Peace, marks the moment a City enters the observance.
The Purpose
Why the Semidon Matters
Give 100 is not only a commemorative observance but a civic founding with permanent institutional consequence. The Semidon matters because it turns symbolic tribute into disciplined public action: 100 Commonwealth Cities, each convening structured gatherings of 100 named participants, towards the establishment of Preemptology as a permanent shield against preventable suffering, disease, and premature death.
In Givingtide, 100 signifies total participation, total contribution, and total success: 100% of humanity called to give 100% of what each can give toward the 100% elimination of preventable suffering, disease, and extreme poverty.
The Charter
The Five Formal Criteria
A Semidon is constituted only when it satisfies each of the following five criteria without exception.
-
Exactly 100 named participants. A Give 100 Semidon gathers exactly 100 named participants, including the convener or host team where applicable.
-
Not more than 100 minutes. The discipline of time gives the Semidon clarity, dignity, and repeatability.
-
A cause-seeding purpose. A Semidon must seed substantive support for the Sovereign Shield: gifts, pledges, advocacy, partnerships, public commitment, institutional alignment, volunteer support, or other practical contributions.
-
Observance alignment. No Semidon may take place before Give 100 formally opens on 21 September 2026. Preparatory meetings before that date are permitted, but they must not be called Semidons.
-
Named civic responsibility. A Semidon may be named for its City, convener, host, office, institution, or occasion: a City Semidon, Presidential Semidon, Corporate Champion’s Semidon, Birthday Semidon, Natal Semidon, or another appropriate form.
The Observance
Ceremonial Sequence
Give 100 unfolds through a disciplined civic sequence — preparation before the opening, the Opening Semidon on the International Day of Peace, and a year of multiplication across the Commonwealth.
Before 21 September 2026
Preparation
Founding Commissions, Champions, Beacons, hosts, institutions, and citizens prepare the civic ground — issuing invitations, securing commitments, briefing participants, and identifying LAMPs and LAMP Companions. These are preparatory acts, not Semidons.
21 September 2026
Opening Semidon
On the International Day of Peace, each of the 100 Commonwealth Cities may open Give 100 through an Opening Semidon.
The Observance Year
Multiplication
From 21 September 2026 to 21 September 2027, each City aims to convene at least 100 further Semidons through the observance year.
On 21 September 2027 — the International Day of Peace — the Sovereign Shield culminates with the final Semidon in Toronto, convened for 100 LAMPs. Peace through preemption is the closing logic of Give 100 and of the Founding.
Stewardship
Philanthropic and Fiduciary Purpose
Where a Semidon generates support, it serves a single, clearly defined objective — the founding of Preemptology — governed by institutional trust and directed towards lasting public benefit.
Sovereign Shield
Support seeded through Semidons adds to the Sovereign Shield’s objective of US$100 million for the Institute of Preemptology.

These contributions help establish the Institute of Preemptology, of which QE2C is a part — alongside the training pipeline, mobile health systems, and Preemptive Health Zones.
Learn more →Trust & Trusteeship
Major project funds are held only through approved fiduciary trusteeship or authorised financial custody arrangements. A Chapter may raise modest local operational support, but a Semidon itself is not a separate fiduciary body.

Honour and Distinction
Give 100 recognises both those who mobilise the Commonwealth’s giving and those who carry its enduring civic dignity — without blurring the lines of governance.
A City’s Call
One Hundred Named Participants.
Not More Than One Hundred Minutes.
The Semidon is the disciplined gathering unit of Give 100: exactly 100 named participants, not more than 100 minutes, assembled to seed the common good. Through Semidons, the Commonwealth tribute to Queen Elizabeth II at 100 becomes a living shield against preventable suffering — common wealth, common health, and common peace in civic motion.
