Culture
1763

Royal Proclamation of 1763

Britain attempts to regulate colonial expansion westward, recognizing Indigenous land rights. The proclamation becomes a foundational document in Indigenous land law — and a source of colonial frustration.

TreatyDiplomacy
1763

Pontiac's War

A pan-Indigenous resistance movement led by Pontiac challenges British expansion in the Great Lakes. The Haudenosaunee largely remain allied with Britain, but the uprising demonstrates growing Indigenous opposition to colonial land grabs.

Conflict

His first marriage, to the daughter of an Oneida chief. She passes away around 1771. He later marries her half-sister Susanna and finally Catharine Adonwentishon.

Culture
1768

Treaty of Fort Stanwix

A major land-cession treaty negotiated by Sir William Johnson. The Haudenosaunee cede vast territories south and east of a line running through New York and Pennsylvania. Thayendanegea serves as interpreter. The treaty reshapes the map of Indigenous territory.

TreatyDiplomacy
1770s

Oquaga Mission Community

Diplomacy
1775

ConflictDiplomacy
November 1775

Diplomacy
June 1776

Returns from London

Thayendanegea returns to America with British assurances about land protection. He immediately begins organizing Mohawk and allied forces in support of the Crown.

Diplomacy
July 1776

American Declaration of Independence

The Declaration of Independence refers to Indigenous peoples as "merciless Indian Savages" — a phrase that reflects the racial attitudes shaping colonial policy and war propaganda.

Diplomacy
August 1777

Battle of Oriskany

A devastating battle pitting Mohawk and Seneca warriors (with British allies) against Oneida warriors (with American militia). Haudenosaunee fight Haudenosaunee — a moment of unimaginable tragedy for the Confederacy.

Conflict
October 1777

Battles of Saratoga

The American victory at Saratoga becomes the turning point of the Revolution, bringing France into the war. For the Haudenosaunee, it signals that the British may lose — raising the stakes of their alliance.

Conflict
November 1778

Cherry Valley Engagement

A controversial frontier engagement. Colonial accounts call it a "massacre," but evidence suggests Thayendanegea attempted to protect civilians. The event becomes a propaganda touchstone used to justify retaliation against Haudenosaunee communities.

Conflict
June–September 1779

Sullivan-Clinton Campaign

General John Sullivan leads a scorched-earth campaign through Haudenosaunee territory, destroying 40+ villages, burning crops, and leveling orchards. This campaign devastates the homeland and displaces thousands. It is one of the largest acts of deliberate destruction against Indigenous communities during the war.

Conflict
August 1779

Battle of Newtown

Thayendanegea's forces confront Sullivan's army at Newtown (present-day Elmira, NY). The Haudenosaunee and British forces are outgunned and retreat, unable to stop the campaign of destruction.

Conflict
1779–1780

Refugee Crisis at Fort Niagara

Thousands of displaced Haudenosaunee people shelter at Fort Niagara. The winter of 1779–80 is brutal, and many die from exposure, disease, and starvation. The British provide inadequate support to their allies.

ConflictCulture
1780–1781

Continued Border Raids

Thayendanegea leads raids across the Mohawk Valley and Schoharie Valley, targeting military and supply targets. These actions are part of the broader frontier war that devastates both Indigenous and settler communities.

Conflict
September 1783

Treaty of Paris — The Great Betrayal

Britain cedes its North American territories to the United States without any provisions for its Haudenosaunee allies. The treaty does not mention Indigenous nations at all — a devastating betrayal of people who fought and suffered alongside the Crown.

TreatyDiplomacy
1783

Thayendanegea Lobbies for Land

After the Treaty of Paris, Thayendanegea travels to Quebec to lobby Governor Haldimand for land grants to compensate displaced Haudenosaunee. His argument: they fought as allies, not subjects, and deserve sovereign territory.

Diplomacy
1784

Treaty of Fort Stanwix (Second)

The United States imposes a punitive treaty on the Haudenosaunee, forcing cession of most of their remaining lands in New York. The treaty is conducted under duress and Thayendanegea does not participate.

Treaty
October 25, 1784

The Haldimand Proclamation

Governor Haldimand grants the Haudenosaunee a tract of land along the Grand River — "six miles deep from each side of the river beginning at Lake Erie and extending in that proportion to the head of the said river." This becomes the foundation of Six Nations of the Grand River.

TreatyDiplomacy
1785

Chapel of the Mohawks Built

The first church in Upper Canada (Ontario) is built on the Grand River. Thayendanegea brings a silver communion set given by Queen Anne to the Mohawk people in 1712. The chapel still stands today as a National Historic Site.

Culture
1785

Resettlement of the Grand River

Approximately 1,800 Haudenosaunee people, led by Thayendanegea, resettle along the Grand River. The community includes members of all six nations plus allied peoples — a diverse new beginning in a new land.

Culture

Second London Visit

Thayendanegea returns to London to advocate for compensation, land rights, and the formal confirmation of the Haldimand grant. He meets with government officials and presses the case for his people's sovereignty.

Diplomacy
1790s

Land Sales Controversy

Thayendanegea sells and leases portions of the Haldimand Tract to generate revenue for the community. This generates opposition from other Haudenosaunee leaders and from the colonial government, which disputes his authority to dispose of the land.

DiplomacyTreaty
1793

Pan-Indigenous Confederacy Proposed

Thayendanegea proposes a broad Indigenous confederacy uniting nations from the Great Lakes to the Ohio Valley in defense of collective land rights. The idea does not fully materialize but reflects his vision of united Indigenous resistance.

Diplomacy
1795

Simcoe Patent Dispute

Lieutenant Governor John Graves Simcoe issues a new patent for the Grand River land that significantly reduces the original Haldimand grant. Thayendanegea protests vigorously, arguing the reduction is a violation of the original agreement.

Treaty
1797

Treaty of Big Tree

Seneca lands in western New York are ceded under the Treaty of Big Tree. The ongoing erosion of Haudenosaunee territory continues despite attempts at resistance.

Turning Points

Key Decision Points

History pivots on decisions. These five moments shaped the trajectory of Thayendanegea's life and the fate of the Haudenosaunee.

1763

Choosing Western Education

The young Thayendanegea enrolls at Moor's Charity School. This decision — likely influenced by Sir William Johnson — gives him English literacy, Latin, and a window into European culture. It also places him at a crossroads: he must now navigate between two complete systems of knowledge.

Impact: Created the bilingual, bicultural capacity that made him the most effective Indigenous diplomat of his era.
1775

Journey to London

Thayendanegea sails to England with Guy Johnson to make the Haudenosaunee case directly to the Crown. He meets King George III, sits for Romney's portrait, and secures promises of post-war land guarantees.

Impact: Internationalized the Haudenosaunee cause and established personal relationships with British power — but also deepened commitment to the Crown alliance.
1777

Siding with Britain in the Revolution

The Haudenosaunee Confederacy splits. Thayendanegea leads the Mohawk and most Cayuga and Seneca into alliance with Britain. The Oneida and Tuscarora side with the Americans. The Great Peace is broken.

Impact: Split the Confederacy for the first time in centuries. Led to devastating consequences for all six nations, regardless of which side they chose.
1784

Negotiating the Haldimand Proclamation

After the war, Thayendanegea secures a land grant along the Grand River for the displaced Haudenosaunee. Governor Haldimand promises land "six miles deep from each side of the river" — approximately 950,000 acres.

Impact: Created the largest First Nations reserve in Canada. But the scope and nature of the grant remains legally contested to this day.
1790s

Selling Portions of the Haldimand Tract

Thayendanegea sells and leases blocks of the Grand River land to raise revenue for the community. Other Haudenosaunee leaders oppose these sales, arguing land should be held collectively.

Impact: Generated short-term resources but created long-term disputes over land sovereignty that remain unresolved. The 950,000-acre grant has shrunk to approximately 46,000 acres.
