The Halifax Explosion of 1917
On December 6, 1917, one of the largest man-made explosions prior to the atomic age occurred in Halifax, Nova Scotia. A French cargo ship carrying explosives collided with another vessel in Halifax Harbor, triggering a massive blast that devastated the city. Nearly 2,000 people were killed, thousands were injured, and much of Halifax was destroyed. The disaster happened during the winter, leaving survivors exposed to harsh conditions.
Boston’s Immediate Aid
News of the explosion reached Boston quickly. Despite wartime shortages and difficult travel conditions, Boston responded immediately, sending doctors, nurses, medical supplies, and relief workers by train within hours. Boston’s assistance played a crucial role in treating the injured and supporting Halifax during its darkest days. This act of compassion left a lasting impression on the people of Nova Scotia.
A Gift of Gratitude
In the years following the disaster, Nova Scotia sought ways to express its gratitude. In 1971, the province began an official tradition of sending a Christmas tree to the city of Boston each year as a symbol of thanks for Boston’s aid in 1917. Since then, the tradition has continued annually.
The Tree Itself
-
The tree is typically a white spruce, balsam fir, or red spruce, harvested from forests in Nova Scotia.
-
It is usually 40–50 feet tall and selected with great care.
-
Each year, a different Nova Scotia community is chosen to donate the tree, often with local ceremonies marking its departure.
Lighting on Boston Common
Once transported to Boston, the tree is placed on Boston Common, America’s oldest public park. The tree lighting ceremony, held in late November or early December, officially marks the start of the holiday season in the city. The event includes music, public celebrations, and remarks emphasizing the historic bond between the two regions.
A Symbol Beyond Christmas
The Boston Common Christmas Tree is not just a festive tradition—it represents:
-
Gratitude across borders
-
Human compassion in times of tragedy
-
A century-long friendship between Boston and Nova Scotia
Even more than 100 years after the Halifax Explosion, the annual gift serves as a reminder that acts of kindness can create lasting bonds between communities and nations.
