The Movement
People-led and permanent. The global campaign of Givingtide International, conducted in the International Decade of Strengthening of Peace for Future Generations, 2027–2036, to establish and propagate the Three Instruments of Peace: GIVA, Preemptology and Centory. 2027 is the Inaugural Year.
One Campaign. Three Instruments. Everywhere, and Permanently.
Give 100 is the sole and permanent campaign of Givingtide International, and the single vehicle through which the Three Instruments of Peace are established and adopted worldwide. Where a nation requires its own civic narrative, the campaign takes the form Give 100 followed by the country; in all global material it is Give 100 without qualification.
Its governing principle is the Rule of 100: one hundred per cent of humanity giving one hundred per cent of what each can give toward the complete elimination of preventable suffering, disease and extreme poverty.
Its present historic work is conducted in the Decade, the ten years from 2027 to 2036 proclaimed by the United Nations General Assembly for the strengthening of peace for future generations. Within it, Give 100 exists to establish three permanent instruments of peace — GIVA, Preemptology and Centory.
Give 100 is constituted by individuals, carried by institutions and civic actors, and organised city by city through Chapters. Anyone may begin. Any adult may register to convene a semidon; a gathering that is not registered in advance may still be recorded as a Give 100 Gathering.
It is a rule of participation and proportion, and not a demand that everyone possess or give the same amount. It asks no person for more than they have, and excuses no person on the ground that they have little.
Givingtide rejects the hierarchy of giver over receiver. Those whose suffering is relieved participate in the moral order of the movement as surely as those who contribute money, skill, time or influence; and because beneficiaries are participants, the future generations in whose name the Decade is proclaimed are participants too.
2027 is the Inaugural Year. The campaign does not end with it, nor with the Decade: the Rule of 100 is a standing call, and the Decade is the campaign’s founding period.
Give 100 answers the Decade’s invitation by establishing the Three Instruments of Peace.
The Rule of 100
One hundred per cent of humanity, giving one hundred per cent of what each can give, toward the one hundred per cent elimination of preventable suffering, disease and extreme poverty. Its primary meaning is the participation of everyone; the hundreds of the campaign are signs of the Rule and not substitutes for it.
A canonical semidon has a roll of exactly one hundred named adults, one hundred commonweal candles or lights, and a duration of no more than one hundred minutes. The host is one of the hundred, and the general form is ninety-nine and one. A complete registered roll of one hundred is the canonical count however many attend on the day, and the Registry records four numbers for every semidon: those registered, those confirmed, those who attended, and the estimated reach.
Its irreducible act is the Enkindling. Those present enkindle their personal commonweal lights; the host enkindles the hundredth; and any balance required to complete the hundred is enkindled in the Commonweal Candelabrum. All one hundred lights are then alight together for one hundred seconds, the Commonweal Acclamation is spoken aloud together — Common weal; common health; common peace — and the lights are set in the Candelabrum, where they form the Triangle of Light, before which the Silence of Inward Commitment is kept. The commitment is personal and is never a public oath.
The roll and the lights signify different dimensions of the Rule. The roll of one hundred named adults signifies the call to everyone; the hundred lights, completed even where fewer are present, signify total commitment, and stand for the fullness of a human life. Completing the hundred lights is no representation that one hundred persons were present, and only those present are recorded as attendees.
A semidon qualifies when it is registered before it is held, opened by the Enkindling and reported to the Registry; no outcome is required, and a semidon that produces only the Enkindling has fully qualified. A gathering of fewer than one hundred, or one not registered in advance, that performs the Enkindling and is reported is a Give 100 Gathering, recorded in the Register as a gathering rather than a canonical semidon. The year carries a hundred of its own: the Hundred Days to Zero, from 22 September to 30 December, in which the movement makes good what the Day of Account showed wanting.
The Rule is the architecture, not the burden. Participation by everyone does not require hosting by everyone: one host creates participation for as many as ninety-nine others; participants become hosts; hosts convene again.
A Civic Movement
Citizens on six continents are establishing three permanent institutions at once: a standard that orders generosity, a discipline that owns prevention, and a council that keeps completed leadership in service.
Give 100 is carried by its participants. It grows through the semidons and Give 100 Gatherings they convene; through GIVAs, the members of the Give 1% Alliance, who adopt the 1-1-1 Framework; through Chapters and their Circles, which organise a city; and through the Centory, the emeriti council in which a city’s completed leadership is seated.
In every city three Champions stand for the estates of Learning, Enterprise and Civic Trust, with Beacons as the recognised advocates of Give 100 in a city’s institutions and communities, and the LAMP as the philanthropist whose generosity anchors the founding. Every Champion advances all three Instruments within their own catchment.
Institutions host as persons do. A school, a club, a company, a hospital, a faith community or a Centory may register as a host, is named on the roll by its own name, and carries its own record. Host and Guest standing begin at eighteen, and no person under eighteen is counted toward a semidon, entered in the Registry, the Rolls or the Scroll, or named in any published list.
Any adult may register a semidon, convene it and report it. The Office of the Citizen is the premier office of Give 100, held by everyone who takes part, and every designated office in the order exists to serve it rather than to stand above it.
GIVA is the Give 1% Alliance. Persons and institutions join by adopting the 1-1-1 Framework, and are organised city by city in Chapters, with professions, companies, campuses and faith communities forming Circles, ordinarily of at least ten GIVAs, under their own Conveners.
A city constitutes a Chapter and, upon the election of its fifth Centorian, a Centory: the emeriti council of the city, of no more than one hundred Centorians, ten of whose seats are reserved for emeriti professors of its universities.
The Hundred Invited Cities
In the Inaugural Year Givingtide initiates the founding of Chapters in one hundred cities. They are chosen in nine categories by published data, applied in the order given; each city is counted once, and each carries the title of the category that seated it.
Invitation is not monopoly. From 1 January 2027 any city in the world may apply, and every city passes the same readiness gate on the same terms. A city that constitutes its Chapter during 2027 is an Inaugural City, whether it was invited or applied.
A city constitutes when it has a Founding Commission in place, a registered address and its constitutional instruments settled, five Centorians elected and approved, not fewer than twenty registered GIVAs, and one semidon convened. Cities pass at their own pace.
Each category runs down its ranking until it holds its number of cities not already seated; for a nation-level category the seat is the nation’s most populous city, or its capital where that city is already seated, or it passes to the next nation. The lists were computed in September 2026 from the tables then current, and where a dataset ceases or changes its method the Secretariat publishes a successor of the same kind.
The Chapter at Enugu, as the seat of the Institute, is founded without invitation and stands outside the hundred. Three numbers state the ambition beyond the Inaugural Year: in every year of the Decade Givingtide seeks to initiate the formation of Chapters in one hundred cities, drawn by the same nine categories running down their rankings past cities already founded together with the cities that have applied; it seeks the constitution of twenty Chapters in every year; and every city on earth is the horizon.
Invitation distinguishes the hundred. The gate is the same for every city.

The Three Instruments installed together at Oslo. The Institute founded at Enugu. Carried through cities on six continents.
On Founding GoodTuesday, the Day of Account, the International Day of Peace, 21 September 2027, the Global Founding Semidon is convened at the International Headquarters in Oslo, and the three Instruments of Peace are installed together as the architecture Give 100 is to establish. The Institute’s own founding semidon is convened at Enugu the same day. In every city the founding seeks the university community first: its retired professors for the Centory and its curatorship, its faculty and students for GIVA, and its medical and public-health schools for Preemptology, which is itself an academic discipline.
Why This Movement Exists
Three immense human resources are badly ordered: generosity exists without a common discipline; prevention is practised everywhere without one profession accountable for its whole; and the accumulated wisdom of completed leadership is too often treated as spent. Givingtide exists to give each a permanent institutional home.
Institutional giving is abundant, uncoordinated and largely blind to the poorest tenth of humanity. One per cent sits within the operational capacity of every class of member the Alliance gathers; what is wanting is that giving it should be ordinary. GIVA supplies the standard that orders generosity.
By the World Health Organization’s reckoning, four in five heart attacks and strokes, and between a third and a half of all cancers, could be prevented with what is already known. Yet prevention is dispersed across campaigns, departments, specialties and short-term interventions, with no clinical discipline responsible for it as one object. What is owned by everyone in general is owned by no one in particular.
The accumulated judgement of those who have carried the highest offices of a city and laid them down is treated as spent rather than as the civic reserve it is. The Centory gathers completed leadership into a standing council and returns its standing, judgement, influence and social capital to service.
Each Instrument unites a class of givers, and by uniting them makes peace. GIVA unites the givers of means, for the world’s prosperity; Preemptology the givers of health, for its longevity; the Centory the givers of wisdom, for its sagacity.
What the Movement Builds
Three permanent institutions, always in constitutional order: GIVA, Preemptology, Centory. GIVA orders what we have; Preemptology protects how we live; the Centory places what we have become at the service of those who follow.
The Give 1% Alliance. A GIVA is an institution or chartered individual that has adopted the 1-1-1 Framework. Core Equity Giving is one per cent a year directed to the world’s poorest tenth, and is the whole of the financial commitment. Cross-Continental Giving carries not less than one per cent of a member’s annual giving across a continental boundary, a rule on the allocation of what is already budgeted for philanthropy rather than a further ask. The Universal Project is one global project of civilisational significance; a GIVA may support it from within Core Equity Giving, and the choice to do so is free. A designated project continues until its completion condition is met or it is retired for cause; the Universal Project designated for 2027 is the Institute of Preemptology. One per cent is all that GIVA asks: three uses of one per cent, and not three per cents.
The discipline of eliminating the preventable dimension of disease: through primary, secondary and tertiary prevention, across every domain of medicine, for every demographic, in every context and at every scale. Its work is zeroward, directed toward zero preventable suffering and zero preventable disease, and it gives prevention a clinical home and an accountable practitioner, the preemptologist. The Institute of Preemptology, Instop, is founded at Enugu as a wholly independent establishment, with the capacity to train ten thousand preemptologists within the Decade. Givingtide founds it, funds it through the charitable architecture and advocates for it; from its installation it is not owned, governed or controlled by Givingtide.
The emeriti council of a city and the apex civic and ceremonial council of its Chapter: a gathering of completed leadership, founded on the principle of the greatest for the least. Centorians are elected, in confidence, to a lifelong civic dignity, and return accumulated standing, judgement, influence and social capital to continuing service. Every Centorian is a GIVA, and the Centory’s core vocation is to advocate and advance the 1-1-1 Framework. A Centory comes into being upon the election of its fifth Centorian; one hundred is a ceiling and not a target, and a Centory of twenty is as valid and as permanent as a Centory of a hundred.
Queen Elizabeth II Centre for Cervical Cancer Elimination
The Queen Elizabeth II Centre is the founding flagship of the Institute of Preemptology and Preemptology’s proof of concept. Its object is the World Health Organization’s 90-70-90 elimination strategy: ninety per cent of girls vaccinated by the age of fifteen, seventy per cent of women screened by thirty-five and again by forty-five, ninety per cent of women with precancer treated and ninety per cent of those with invasive cancer managed.
Cervical cancer is the only non-communicable disease for which the world has adopted an elimination strategy, and it is a disease of every country rather than of a region, so that every city on earth can begin on it at once. It is also the disease that best shows the inequity Givingtide exists to end, disappearing in the Global North while nine in ten of its deaths now fall in the Global South.
The dedication honours a life of service. Queen Elizabeth II carried the wisdom of a long public life to its final day and never retired from service, which is the model on which the Centory is built; and her reign made female authority visible at the highest level of public life, which is joined here to a centre for women’s lives. The designation is a programme name: the Royal Household is informed of the dedication as a courtesy, and the name implies no endorsement or control by it.
Elimination means elimination as a public-health problem — an incidence below four cases per hundred thousand women-years — and not the disappearance of the disease.
Opening. Renewal. Founding. Zeroward.

The Decade Opens
Registration opens across the world
Hosts register their semidons, cities apply, and the Founding Roll opens to chronicle the founding of every Givingtide city: its Founding Commissioners, Curators and inaugural members, office-bearers and honorees. The first Founding Commissions and City Centory Curators, appointed on 21 September 2026, begin work.

Givingtide Day · the 1·1·1 Day
Renewal: the recommitment of every GIVA to the 1-1-1 discipline
The Pause is observed for three minutes at 1:11 pm local time, kept as three silences of one minute — Remembrance, for those who did not make it into the new year; Solidarity, with those still living in extreme poverty; and Resolve, in which each dedicates their one per cent to a different year ahead. The constitutional year of every Chapter turns at the Pause, and the Chapter’s annual offices hand over.

Founding GoodTuesday · the Day of Account, the International Day of Peace
The Global Founding Semidon is convened at the International Headquarters, Oslo
The three Instruments of Peace are installed together as the architecture Give 100 is to establish, and the global count of semidons is announced. The Institute’s own founding semidon is convened at Enugu the same day. The Day of Account falls on 21 September in every year; the designation Founding GoodTuesday is historic and belongs to 2027 alone.
-
–The Hundred Days to Zero · in 2027, the Founding Hundred Days
One hundred days in which what the Day of Account showed wanting is made good
The Hundred Days to Zero follow the Day of Account in every year and close the financial year, which is the calendar year; every organ, standard-bearer, member and supporter of the order keeps them. In 2027 they are the Founding Hundred Days. Global GoodTuesday falls within them, on 7 December 2027, the first Tuesday of December and the annual peak of the weekly GoodTuesday.
-
The Close of the Inaugural Year
Three designations close absolutely
Inaugural Cities and their Founding Commissions; Founding Centorys and their Founding Centorians; Founding Hosts and Founding Guests, being the Hosts and Guests of semidons registered in the Inaugural Year. Each pair is conferred in 2027 and closes with it, and is recorded in the Founding Roll, which itself remains open for as long as cities are founded.
The Inaugural Year opens with the Decade on 1 January, renews at the Pause on Givingtide Day, installs the three Instruments together at Oslo on Founding GoodTuesday, and runs through the Hundred Days to Zero — which return in every year from 22 September to 30 December, the Founding Hundred Days being the first of them. The Decade runs to 2036; Give 100 continues beyond it.
The Three Champions
Champions are three to a city, in the triad Learning, Enterprise and Civic Trust. Each speaks for one estate of the city and enlists it, and each advances all Three Instruments within that estate.
The three estates describe the coverage of a city. GIVA is a discipline for universities and civic bodies as much as for companies; the medical and public-health faculties are where preemptology is taught, while the wider Learning estate contains the emeriti professors for whom ten seats in every Centory are reserved; and civic life is where most semidons are convened.
Beside the Champions stand the Beacons, the recognised advocates of Give 100 in a city’s institutions and communities, and the LAMPs. A designation confers honour, which recognises standing, and office, which gives that standing form; it carries no financial, legal or contractual obligation, and no standard-bearer ever receives or holds a gift. Every office other than the Centorian dignity is assumed at a Semidon of Assumption, a GoodTuesday semidon convened for the purpose, by the presentation of the insignia of office and the plighting of the Troth of Office after the Enkindling.
Three estates. Three Instruments. Every Champion carries all three.
The Academic Champion speaks for the estate of Learning: the universities, schools, learned societies and research institutions of the city. Universities are the first seedbed of the Instruments — their faculty and students for GIVA, their medical and public-health schools for Preemptology, and their retired professors for the Centory and its curatorship.
Ten seats in every Centory are reserved for emeriti professors of the city’s universities, in any discipline; where fewer than ten qualify, the seats remain unfilled.
The Business Champion speaks for the estate of Enterprise: the companies, chambers of commerce, professional bodies and industries of the city, enlisted as GIVAs under the 1-1-1 Framework and organised in Circles, ordinarily of at least ten GIVAs, under their own Conveners.
Each Chapter also has a Commission to Encourage Corporate Philanthropy, composed of the chairmen of the ten largest organised private-sector bodies in the city by number of institutional members.
The Civil Champion speaks for the estate of Civic Trust: the service clubs, foundations, associations, faith communities and neighbourhoods of the city. It is the catchment in which most semidons are convened, and Beacons of Faith carry the P.E.A.C.E. charge within faith communities.
A LAMP is one whose generosity anchors the founding of a city’s Chapter and contributions to the Institute of Preemptology. The First LAMP of a city is the first so recognised, and LAMP Companions are those who join a LAMP in that generosity.
The designation is metropolitan and personal, and carries no office of any municipality.
Enter the Founding
GIVA. Preemptology. Centory. Enter the three Instruments, the flagship that proves the discipline, and the case for taking part. 2027 is the Inaugural Year; the door does not close with it.
